01 / About

Who I am

Fullstack developer with 5+ years delivering high-complexity projects for clients such as Itaipu Binacional, Tecnisa, Hospital Sírio-Libanês, and Grupo Fleury.

I work with modern architectures — React, Next.js, Node.js, TypeScript — and also the Microsoft 365 ecosystem (SPFx, Power Automate, Azure AD). I'm currently at Peak One Dev, an agency serving international clients in e-commerce, funnels, and SaaS, with 100% English communication.

I use AI tools (Claude Code, Cursor, Codex, Trae.ai) to speed up delivery without giving up code review, PR approval, and engineering best practices. Based in Matão, Brazil, working remotely with teams and clients around the world.

Reviews

I'm not exactly an impartial voice, but it's a pleasure to say this. I met Gabriel and since then he's been with me on several projects. He's an exceptional developer — not just technically, but in organization and execution too. What I admire most about him is his attitude toward challenges: he doesn't fear the unknown, he embraces it. He's a trusted partner and I hope we keep working together for a long time.

I got to know Gabriel's work as a Power Platform and SPFx developer, and I can say he's an outstanding professional. Beyond technical mastery of the stack and commitment to quality and deadlines, he has the analytical ability to spot strategic process improvements. He doesn't just execute tasks — he analyzes the whole process and proposes optimizations that generate real business value.
