At BAO Systems, I led delivery of ConneX, an enterprise IoT diagnostic platform, defining its React 19 and TypeScript architecture and guiding two developers. I built monitoring interfaces for connected devices and automated TypeScript SDK generation from OpenAPI specifications.

For Dharma Platform, I owned technical delivery of an offline-first React Native app for low-connectivity field environments. I developed synchronization using SQLite and RxJS, including peer-to-peer data sync over Bluetooth Classic.

At HODL Media Inc., I rebuilt a cryptocurrency portfolio app in React Native and launched it on the App Store and Google Play. Earlier, I developed customer self-service portals for MEO, MOCHE, and PT Empresas at Portugal Telecom.
