Lopes
Fullstack TypeScript engineer in Curitiba, Brazil. I build products for the financial market and work across the whole stack, from the database to the interface.
01 / About
I build the whole product, not just the code.
I work as a fullstack TypeScript engineer at Quantum Tech Ventures, in the financial market. Architecture, UX and business constraints are part of the job, and I ship end to end.
Lately I have been deep in AI agents and developer tooling, and in software architecture: domain-driven design, clean architecture and modular monoliths. I also build and run my own product on my own infrastructure.
02 / Work

Delivery Platform
Ordering app for a beverage distributor: a REST API with JWT login and role-based routes, where customers place orders and sellers move them through their statuses. Team of five; I wrote about 30% of it, almost all on the API. Later I started a solo rewrite in TypeScript, Fastify and Prisma.
