Developer, now studying AI engineering

I'm a developer who builds web and mobile products with React, Next.js and React Native. Now I'm studying AI engineering — learning to build with large language models and bring into real products.

About Me

I'm a developer with over three years of professional experience in IT and systems maintenance. At Leader Group I looked after hardware, networking and databases for retail systems — both the cashier front line and the back office — across Leader Hypermarket, Leader Mart, Cement Timor, Auto Timor Leste and Lisun Timor.

Since 2025 I've been an IT Collaborator in the Software Development department at Viettel Timor, Unipessoal, Lda. (Telemor), one of Timor-Leste's leading telecommunications companies, building real applications used by staff and customers.

Skills

I work with AI coding agents like Claude Code every day — and I use with responsibly. I review every line they produce and keep architecture and judgement in my own hands. For me they are a way to ship better work faster, not a substitute for knowing my craft.
