About me

Full-stack developer with 2.5+ years building production web applications — REST APIs in Laravel and Node.js, Angular front ends, relational and NoSQL databases, Docker and CI/CD. I care about readable code, automated tests and shipping things people actually use.

  • 💼 Full-Stack Developer at AGTech Soluções — remote, since March 2024 (mid-level since January 2026). Laravel + Angular + MySQL products (HidroMeter, Topes, PremoPlan) used by clients in Brazil, Singapore and Panama. I designed and own HidroMeter's automatic-trigger module end to end.
  • 🚀 Founder of Kodem ABNT — a SaaS that formats Brazilian academic papers to the ABNT standard: reference auto-fill from DOI/ISBN/URL, a CrossRef-backed reference checker and Word (.docx) export. Angular 20 + Laravel, 500+ active users since its June 2026 launch.
  • 🌍 Open-source contributor — 19 merged pull requests in Laravel, Symfony, Angular, Swashbuckle.AspNetCore and Super Productivity: framework fixes and documentation corrections (see below).
  • 📜 145 TreinaWeb certificates (12 learning paths, 133 courses), each with a public validation link.
  • 🎓 B.Sc. in Computer Science at UNIP (expected December 2027).
