About
I'm Bruno Costa.
Full-stack engineer and designer. I've been building software with React and Node.js for over 7 years. I'm a tech lead at BEES, part of AB InBev, and mentor other developers. I draw, invent, and take things apart. Sometimes I put them back together.

Stack
Building software that solves real problems
Highlighted is what I use day to day.
typescript.ts
// An annotation widens. `satisfies` checks the shape// and keeps the literal types, so routes.case stays a// template literal, not string.const routes = {home: '/',case: '/projetos/aurem',} satisfies Record<string, `/${string}`>;
Backend
Scalable APIs, concurrency and transactional integrity.
Platform & SRE
Pipeline, infrastructure as code and observability.
Architecture & Quality
Decisions recorded in ADRs, explicit module boundaries, coverage that catches regressions.
Mobile
Cross-platform with React Native, without inventing depth.
Projects
From the problem to the deploy
Context, technical decision, and what changed afterwards.
