About

Professional summary

I am a senior full-stack engineer with more than seven years of experience delivering production software across the TypeScript stack. I build web, mobile, backend, and cloud systems with a focus on practical architecture, reliability, and maintainability.

At Quipu, I own a compliance microservice that files invoices with Spain's tax authority. I work end to end, from system design and implementation through production support, using Node.js, Prisma, PostgreSQL, BullMQ, Docker, and AWS EKS.

I also deliver product features for a SaaS platform serving approximately 17,800 paying businesses. My work includes React and TypeScript frontend development, as well as React Native features for iOS and Android applications.

I enjoy designing complete systems and documenting their technical trade-offs. My public architecture projects include a multi-surface events monorepo, a Redis-backed realtime multiplayer game, and a multi-tenant inventory and operations platform.

I am based in Maputo and work remotely with teams across Europe. As a Portuguese citizen with full EU work rights, I am open to senior full-stack and product engineering opportunities, including direct employment, EOR, and contract engagements.

I plan to relocate to Europe in 2027 and value roles where I can take ownership, solve production problems, and contribute across product and engineering disciplines.

Career history

Full-Stack Engineer Quipu

I own the Verifactu compliance microservice end to end, including design, delivery, and production support. The Node.js service uses Prisma, PostgreSQL, BullMQ, Docker, and AWS EKS to file invoices with Spain's tax authority (AEAT), processing more than 52,000 invoices since September 2025.

I improved retry and failure handling to make recurring jobs resilient to database failovers after the service migrated from self-managed Kubernetes. I also ship React and TypeScript features for a SaaS platform serving about 17,800 paying businesses, build React Native features for iOS and Android, and resolve production issues with product and support teams.
