About

Hi!

I'm Murillo, a developer born in Londrina - PR (Brazil). I hold a Computer Science degree from UniCEUB and I'm passionate about building digital products end to end.

Software engineer with 10+ years of experience delivering web and mobile solutions. Recently I've worked as a Frontend Engineer on AI-powered products (Next.js, shadcn/ui, Vercel), as a Full Stack developer on industrial platforms (Next.js, PostgreSQL, AWS, and CI/CD), and at Solfácil with Vue.js, Python, PostgreSQL, Kafka, and GraphQL. I have 5+ years with React Native (Kodiak app at CASSI), state management with Redux/Redux Toolkit and Zustand, and building responsive layouts with modern CSS since the start of my career.

I keep leveling up with new technologies, combining modern frontend, AI integrations, and continuous delivery practices across personal and professional projects.
