Full-Stack Developer — React, Next.js, TypeScript, NestJS, Python. I build corporate systems and put AI agents to work inside real business processes.
Currently a development intern at AIONS (Manaus, AM), where I've shipped a whistleblower channel with TOTP + facial validation, a medical-report platform with digital signature, and an EPI lifecycle tracker — plus the n8n automations that connect them to the company's HR system.
| Project | What it is | Stack |
|---|---|---|
| SisVac 2.0 | Vacation & leave management for the public sector, implementing Amazonas State Law 1.762. Hierarchical RBAC, native PDF, daily-reset live demo. | Next.js · NestJS · Supabase · Turborepo · GitHub Actions |
| TranskriptorSec | Whisper transcription running inside the browser via WebGPU — audio never leaves the user's machine, zero API cost. | Next.js · WebGPU · Web Workers · Prisma |
| Queimadas AM | Wildfire hotspot dashboard on INPE open data. No back-end, no API key — the hard part is the data, which arrives dirty and changes without notice. | Angular 22 · Signals · Zoneless · Vitest |
| FitSec | Offline-first workout PWA: optimistic writes, sync queue, and rest timers handed off to the iPhone's native timer. | Next.js · Supabase · IndexedDB · Service Worker |
Every one of them is deployed and clickable. I'd rather you open the demo than read my CV.
I document decisions, not just code — each README has a section on what I chose, what I rejected, and why. When something doesn't work, it goes in the README as a limitation instead of being sold as a feature: TranskriptorSec's speaker diarization scored 57.2% against a 50% baseline, and it says so.
The parsers and sync queues are tested — 104 tests in FitSec, 57 in Queimadas (22 on the CSV parser alone), plus a contract test that fails on purpose if INPE changes its header.
