About

Servant of God. Husband. Software Engineer.

I’m a software engineer and full-stack developer based in Minas Gerais, Brazil (UTC-3), with 12 years of experience building and deploying applications, from e-commerce platforms to SaaS products.

Nine years as a business partner and co-founder have shaped how I approach both development and business decisions. Security, performance, reliability, and maintainability guide that work.

My technical background includes 9 years with Laravel and deep expertise in its ecosystem, 7 years with Vue.js, and 5 years with React, Next.js, and TypeScript. Production infrastructure experience includes 7 years with Docker and 3 with Kubernetes.

Since June 2025, I’ve been building open-source prediction market infrastructure at Kuest, working with React, Next.js, TypeScript, and PostgreSQL.
