About

Frontend engineer based in Vale de Cambra, Portugal, with about eight years building React and React Native products. Employed at Mobiweb since 2018. Currently outsourced to Vodafone as a Senior Software Developer Specialist on a renewals digitalisation squad.

Until 31 July 2026, outsourced to Celfocus on Jawwy — a telecom platform sharing business logic across a web portal, a mobile app, and a dedicated library. Started as a junior on the mobile app and grew into a tech lead across those three repositories: reusable components, centralized API clients, custom hooks, and a zero-warning TypeScript codebase. In 2023 helped stabilize Ooredoo’s frontend under a tight timeline.

At Mobiweb also shipped government and retail apps (Junta+, GamingReplay, marketplace dual apps) and mentored juniors on architecture and code quality. Focus: clean, readable code, shared libraries, and making complex systems easier to work on.
