Coding Agents are here: how can we make the most of them?
Agentic AI is reshaping how we write software, but not every agent is suited for every task and they don’t all behave the same way. I’ll share what I’ve learned as a Software Developer trying to keep up with the latest tools: what actually helped me, what didn’t and guidance on surviving this constantly changing environment. All demos and examples are based on GitHub Copilot, including the latest features announced at GitHub Universe 2025.

Better Together: Giving and Learning through Open Source
Being part of open and collaborative communities means giving without expecting anything in return. When everyone does that, you end up receiving far more than you could ever imagine. In this session, I’ll share my journey of becoming an Open Source maintainer and the invaluable lessons I'm still learning along the way. I wish I had known some sooner! You’ll discover how contributing to a global community not only improves your technical skills but also helps you grow as a better human being.

Coding Agents are here, keep your sunglasses on
Agentic AI is reshaping how we write software, but not every agent is suited for every mission and they don’t all behave the same way. I’ll share what I’ve learned from hands‑on coding sessions, tool comparisons and personal research: what actually helped me, what didn’t and guidance on surviving this constantly changing environment. I’m sharing my secrets with you, just in case I get neuralyzed. (yes, the conference was themed on Man in Black)

TanStack Start: a fresh take on React full-stack applications
It’s time to meet TanStack Start, a full-stack React (and Solid) framework with a client-first philosophy and an unprecedented developer experience. Built on Vite, it lets you forget about confusing APIs and clunky mental models (use server/use client, I'm looking at you). With this framework, you can colocate your server logic alongside your client code, do some Server Side Rendering, and still keep all the benefits of a Single Page Application. Let's see how TanStack Start rethinks the full-stack React workflow and why it might just become your new favorite tool for building modern, production-ready web apps.

These 4 services let you pick from a list of LLMs and use them for free, I found them as I'm developing some AI features on a side project for learning purposes and thought was worth sharing. Going in production clearly requires a paid plan with higher limits but for learning or evaluating purposes these work great.
