About this gig

  • I build cross-platform mobile apps with Flutter that run on both Android and iOS from a single codebase, backed by a real database and a proper backend.

My most recent project is an offline-first inventory app now in live use at a commercial construction site. It tracks materials and stock movements, captures photos, and keeps working when there is no network, syncing automatically once the connection returns. That is the standard I build to: software that holds up in real conditions, not just in a demo.


WHAT I CAN BUILD FOR YOU

  • Business and productivity apps (inventory, booking, tracking, internal tools)
  • - Apps with user accounts, roles and permissions
  • - Offline support with automatic sync
  • - Photo and file capture, dashboards and reports
  • - Clean database design with Supabase, Firebase or PostgreSQL

WHY WORK WITH ME

I am a Computer Science graduate with professional software QA experience, so what I deliver arrives tested and documented. You get the full source code with every package.


Please message me before ordering with a short description of your idea, and I will tell you honestly whether it is a good fit and which package suits it.
