Dev Lead & Senior Frontend Engineer. 6 years building and shipping web and mobile products end-to-end, mostly in fintech and retail. I lead a team of 4 under Scrum, own the frontend architecture and code standards, and ship to production — App Store, Play Store and web.

Cross-platform products where one codebase serves web, PWA and native — React Native (Expo) and Next.js, always TypeScript. I own the whole surface: design systems, i18n, offline-first data, auth, releases. When the bottleneck is the team rather than the code, I own that too: sprint planning, code review, technical mentoring.

Leading — a team of 4 developers under Scrum: sprint planning and tracking, code standards and a review process that cut rework, onboarding and mentoring, frontend architecture decisions across the mobile app, web portal and back-office.
Fintech surface I've shipped — IBAN account opening, SEPA transfers, physical and virtual Mastercard cards, Apple and Google Wallet, biometric authentication, QR payments, admin back-office. Mobile app live on the App Store and Play Store.
Before that — DiBanka's frontend from 1.0 through the full 2.0 redesign, plus its admin panel; Workiando and MoneyMarker at Fox Solutions; digital products for the D1 retail chain (KOBA D1, Tiendas1500, Cocinando con D1) at Heinsohn.

- Design system first. Tokens before components, components before screens — it's why these apps look intentional instead of assembled.
- Ship to real users. Everything above is deployed and in use, not a tutorial repo.
- Multilingual by default. No hardcoded strings; several of these ship in three languages.
- One codebase, many platforms when it makes sense — native-only when it doesn't.
Building Parlo — an English tutor that explains corrections in Spanish; currently shipping the B2 curriculum. Keeping Bowlify and Spendia in production with real users.
