What I'm looking for

I'm open to contractor or Employer-of-Record engagement, with remote work and full overlap with European hours.

At Wintoo, I build and maintain a production social-commerce app with more than 100 screens, including storefronts, checkout, wallet payments, and real-time chat. I also shipped an in-app AI assistant for job search and matching, and instrumented user journeys with Firebase Analytics and Crashlytics.

I built Hisab end to end as a multi-currency accounting and remittance SaaS, with offline-first sync, a double-entry ledger, and financial reporting. Earlier at Hexa ICT, I shipped more than 50 Android and iOS apps and led 19 projects through architecture and app-store delivery.
