The unfolding AI revolution presents us with unique opportunities, challenges and responsibilities for designing our future. Learn how to exercise your critical thinking skills when it comes to integrating AI in your design craft, and how to build a solid ethical mindset around making design decisions in the Age of AI. Guided by Ioana Teleanu, the Lead Product Designer for AI at Miro, we'll explore the main themes that we need to reflect on as designers participating in shaping the future of humanity.

Anyone who worked in tech, for any amount of time, knows that the landscape is in constant motion. The technologies of today are obsolete tomorrow. The tools of the trade are in constant motion, and continuous upskilling is the bread and butter of all software engineers who survive the passing waves. The software engineers of the future are those who mastered 1 skill: adaptation. In this talk, I will address the evolution of our craft, and my predictions for the core competencies of the future.

Building a business is a slugfest to see who gets more customers first. You have to adopt that mindset when writing code. As an old boss told me once: Clean code won't matter if we're dead. You have to shift your mindset from best practices to getting shit done. But you can't go too wild or the tech debt will kill ya. 

Gear up for a speed competition, it's ChatGPT versus yours truly, racing to build a data visualisation platform from scratch at top speed. Who will win? We’ll be taking on the challenge of reconstructing an energy generation visualisation platform, drawing inspiration from the likes of GridWatch and the Energy Dashboard.

In Star Wars, Pit Droids are repair droids designed to maintain racing vehicles "podracers". These droids are 1.2 meters in height and can fold when not in use. Their funny behavior is explained in a way that they were programmed with a sense of urgency but without enough processing power to perform some complex tasks.I will show you how I built a realistic Pit Droid and empowered it with NVIDIA Jetson Orin Nano. The droid can perform AI object detection, move its head toward the objects, and more. You will also see some other droid projects I worked on.NVIDIA Developer post: https://blogs.nvidia.com/blog/2023/08/03/goran-vuksic-pit-droid/Hackster project: https://www.hackster.io/gvuksic/nvidia-jetson-orin-nano-powered-pit-droid-7da0e8Through this session, you will:- hear how this robot was assembled,- learn about Azure AI Studio & Azure Custom Vision- learn how to easily prepare and tag images for model training,- see how to train a model for object detection,- analyse images from the camera of the robot,- control motor and other IoT devices connected to the robot,- and much more.I hope this session will give you a great introduction to AI and IoT, and inspire you to build similar projects on your own!"

Back in the late 90s, I worked as a radio newscaster and used computers as a hobby. First writing pretty pointless programs, then playing games, being bad at them and analysing the games how to give myself endless lives. Then I got access to the web and everything changed. I knew, this was the medium to support for the rest of my career. Here is a recount of 25 years of professional web development. The technologies that came and went, the struggles to get the resources I need and the wonderful, wild and bonkers things and people I encountered. And you also get an outlook why some products and technologies succeeded and why others failed.

Being pragmatic and understanding the tasks are crucial for effectively achieving your activity as a software developer. Unfortunately more is needed to acquire successful software. At this point, you need to go beyond and understand the strategy and tactics of the software engineer.Good software is closer to business and needs to be ready to change often. Rewriting the whole system from scratch becomes a real temptation. New shiny solutions like microservices pretend to solve this problem using new technology. But is there any guarantee that this feeling won't come up again after some time?It does not matter if it is a micro, nano, or even atomic service; no new buzzword or trend can help us with this problem.So here's the answer you've been looking for: you must explore multiple tactics and strategies in software engineering practices, such as documentation, testing, domain-driven design, persistence, cloud adoption, and the different design and architecture styles.This interaction will cover the ultimate guide to making the best use of architecture and design to guarantee a better, maintainable, and evolutionary solution. You'll also learn how to avoid complex systems and fight against legacy to achieve the desired innovation with stability.

In the field of software development, collaboration is key. Yet, many developers find themselves working in teams without ever being taught how to effectively express their opinions and ethically influence their colleagues to align with their vision and goals.In this practical and enlightening session, we delve into the science of influence. By understanding the psychology of why people say yes and how to apply these insights ethically in business, we explore the psychological triggers that drive human behavior. Participants will learn how to communicate considerately yet persuasively, inspire cooperation, and foster a culture of collaboration within their team.Whether you're leading a project, seeking buy-in from stakeholders, or simply aiming to improve team dynamics, mastering the art of influence can lead to smoother workflows, better decision-making, and ultimately, greater success. This session will share proven practical strategies and techniques for harnessing the power of influence to create a more productive and harmonious work environment.

Recently I was asked: “but Rita, aren’t you a Software Developer? Isn’t you job to write code? Why do you keep pondering about people?” My answer was simple - “because it is not up to a person to build quality software. It takes a village”. Software Development and People can not be seen as two separate concerns by companies. There is a natural entanglement between the two of them that I would like to explore a bit in this session.

In an AI-driven world where information overload is the norm, it's all too easy to rely on ChatGPT or Google Search for quick answers, only to forget them just as quickly. But what if there's a smarter approach that not only helps us retain what we learn but also enhances our workflow and productivity?
We will explore why and how constructing a Second Brain can revolutionize the way developers work. By shifting our perspective and relying on our internal knowledge base, we can forge connections that enhance memory retention and improve our overall workflow. This presentation aims to delve into the core of the developer workflow, addressing commonly shared questions that are typically googled or answered using ChatGPT. Instead, we will focus on how adopting the habit of turning to our Second Brain can yield better results by providing answers in the context of our previous learning.

“Hell is other people.” There are many talks on how to get started as an engineer and how to step into management, but there are few talks about how to be an adult in (professional) relationships. I’ve spent my career in small companies and startups, FAANG organizations, and opensource communities. Each of these spaces demands different things of the people in them, yet across these spaces all succeed and fail along the fault lines of a core set of soft skills: regulating emotions, setting boundaries, framing experiences productively, and letting go. In this talk, I share everything I’ve learned in my career that has helped my colleagues, mentees, and friends so that you may navigate the most difficult part of tech—people—with grace, empathy, and safety.

Probably the most noticeable change engineers experience when they become leaders is the increase of day-to-day chaos. The moment you become responsible for the work of a team or a large area, tasks start coming at you. Dozens of them! Sometimes, per day. And also, questions. From everyone and their dog! And finally, meetings. Lots of them, long and short, exciting and boring... Does it sound familiar?
To me, very. And it took me quite some time to figure out what to do with that. I'm going to share my recipe for taming the chaos with you. I'll talk about the components of that chaos, of reasons that they occur, and about solutions for avoiding it.

Additionally, it delves into identifying seniority traits beyond technical expertise, promoting diversity, and continuous improvement through feedback. Participants will gain insights to transform interviews into meaningful engagements that find talent and potential future leaders.

We all have our very own wellbeing processor.It influences how you feel and act. It leads to every outcome you’ve ever had or will have…For most of us, our wellbeing processor is primarily fed by our very own AI.Unfortunately, our AI often seems to work against us.In this talk, you’ll learn how to take back control and train your AI to work with you to promotes a growth mindset and optimise wellbeing.

Join me for "Pixels, Promises, and Panic" as we delve into the world of frontend mishaps. We'll share 4-5 real-life horror stories from the trenches of web development. From baffling browser bugs to cringe-worthy code catastrophes, these tales are a mix of humor and caution. Whether you're a seasoned developer or just starting out, these stories will entertain, enlighten, and remind us all of the unexpected twists and turns in the world of coding.

After years of rapid growth, the winds have changed in many tech companies, with strategy changes, budget cuts, restructurings, and layoffs. Productivity and efficiency have become the business buzzwords of the season, and while pressure towards “more engineering productivity” is mounting in many organizations, it can be difficult to apply these abstract concepts to engineering teams and turn them into concrete actions that don’t alienate your team and lead to lasting impact that aligns with your stakeholders’ needs. I’m here to help. In this talk, we’ll go: - Beyond buzzwords: What do productivity, efficiency, and effectiveness mean? - Beyond “implementing DORA metrics”: How can you understand and improve your team's productivity as a technical or people leader?- Beyond your team: How can you manage up effectively to keep your bosses informed and ensure alignment with organizational goals?Having led dozens of teams through times of high change, I know that leading during a tech downturn presents unique challenges. You will take away actionable steps to help you improve on your team, and lead successfully through uncertain times.

You're working as a developer, and one day - BAM, you're offered the chance to lead a team, to step into a managerial or leadership position.What now? If I accept the offer, will I forget how to code? Will my skills depreciate? Is there a way back to a specialist path? Can I really be a “manager by day, developer by night”? Will I still be a technical person?I've been at this point! At Atlassian, I undertook an experiment and moved from a senior developer position to a manager role for 15 months... and then I went back to coding.Will my experience help you make a decision if you're facing one - I don’t know. But it will be food for thought 

No developer is an island and no developer is perfect. This means that you cannot create anything without using components written by someone else and these components will have defects or missing features. At some point in our life we all asked for support to someone else.But being a maintainer is not an easy task at all. Think about receiving tons of reports with partial or missing information, or being yelled by strangers for not being responsive or fast enough.For the health of our industry we must love our maintainers more: in this talk I’ll show how to politely ask for help and how to make sure you provide all the necessary informations.

In high-performance environments, the pace is relentless. While it's easy to make quick technical decisions in smaller developer teams, the dynamics shift drastically when dealing with a team of 100 developers. Making significant technical decisions, especially those concerning architecture, without impacting other teams becomes nearly impossible.In this talk, I'll share my experience of structuring an RFCs process at QuintoAndar. We'll delve deep into RFCs, uncovering why they're an indispensable tool for companies aiming to maintain technical excellence, even with a sizable workforce. We'll explore how RFCs facilitate high-level technical decision-making, providing a clear roadmap for changes and empowering everyone to navigate risks with precision.

We all had a manager who doesn’t seem to listen to a single word we say, and if we don’t, it’s probably because we are that person. I’ve been on both ends, but I found a way out of the vicious cycle. The answer is active listening.As leaders, we have a lot of influence and power to make changes. We owe the team the responsibility of taking care of the team members, helping them grow, and supporting them in tough times, and we cannot do this effectively if we don’t know how to actively listen. Why would someone listen to us if we don’t listen to them?Active listening is a communication skill that involves going beyond simply hearing the words that another person speaks, to seek to understand the meaning and intent behind them. Listening builds trust, builds shared understanding, and puts the people on the same side to work toward a solution.Explore with me the meaning of active listening, how it can help us be more effective and empathetic leaders, and how to practice it.

In this presentation, we explore the role of playfulness and hobbies in preventing burnout in the tech industry. Discover how integrating joy and creativity into our work routines can enhance innovation and well-being. Join us for insights and strategies to embrace a more balanced and fulfilling approach to technology work.

There's lots of information out there about reducing cognitive load for users, but what about developers? This talk will cover Cognitive Load Theory, how some disabilities affect it, and designing a development environment around it.

Learn how to create and share professional web development content to expand your reach, advance your careers and establish expert status. This talk will tech you how to share your knowledge effectively through blogs, videos, and social media posts, helping you stand out and connect with others.

The time has come: the DevOps revolution is winding down, and we’re entering the post-DevOps era. We’re at the precipice of a massive generational shift in how we build and understand our software, and CTOs need to prepare.In the past, we were only interested in basic metrics on how we operated our software: reliability, uptime, MTTR, MTTD. Observability 1.0. Companies that settle for these basic data points will not survive in this new era.As engineering best practices around separating deploys from releases, testing in production, observability-driven development have become standardized, the approach to telemetry has stalled, and it’s time for a new version: Observability 2.0.Learn what this new version means for your engineers, and how to embrace this breaking change to:- Save them from drowning in symptom-based alerting- Help fewer people work together to build better software- Create fast feedback loops throughout the entire organization through highly granular visibility into all their systems

Join me on a musical journey through the world of open source software as I share the story behind crafting from scratch an online guitar tuner with Javascript.In this talk, we'll explore the delightful intersection of mathematics and development, where a simple curiosity led to the creation of an open-source tuner using React and Next.js.I'll share insights and challenges into the implementation of the tuner, navigating through the algorithmic landscape of autocorrelation and frequency calculations.
