# Educator & Speaker — Johnny Fekete > Conference talks, a free browser-extension course, and free mentoring through GitNation. Canonical URL: One of the most rewarding parts of my career has been helping others level up their skills. Whether it's speaking at conferences, writing technical tutorials, or creating free courses, I love breaking down complex concepts into something approachable. ## Talks & speaking ### Context Is a Team Sport — Claude Meetup for Builders, 2026 Your team's AI is only as smart as what you teach it together. Most teams teach it nothing. July 21, 2026, Barcelona, ~200 people. One codebase, a whole team, and everyone quietly running their own private AI setup. You don't get a smarter team that way — you get a pile of clever silos. The conventions everyone shares belong in the repo, negotiated the same way you'd negotiate code style. Personal workflows stay personal. The hard part was never the tooling: it's deciding which rules become law and which stay judgment. ### Building Browser Extensions with React That Don't Break Browsers — React Summit US, 2025 Architecture patterns, performance optimizations, and debugging techniques for production-ready extensions. November 18–21, 2025. ### Rebooting Joy: Harnessing Playfulness and Hobbies to Redefine Work in the Tech World — TechLead Conference, 2024 The role of playfulness and hobbies in preventing burnout in the tech industry, and how integrating joy and creativity into work routines enhances innovation and well-being. ### The Freelancer's Dual Role — Toptal Global Talent Conference, 2023 Clients seek both contractors' work and their expert opinion, leveraging their broader industry knowledge and external viewpoint. The key is finding the balance between adding strategic value and delivering the right work. ## Courses **Web Extension Tutorial** — a comprehensive free course on building browser extensions, covering everything from basic setup to production-ready extensions, based on years of building real products. ## Mentorship I offer free mentoring sessions through GitNation.
