Hi, I'm Heng-Seng Ting
Building high-performance
mobile apps.
Selected Works
I built a comprehensive order and POS system allowing users to order and make payments, featuring a dedicated admin portal.
I led the architectural migration of a gig-economy platform for freelancers and hirers from legacy native Android and iOS apps to a unified React Native codebase.
I developed custom parsing algorithms in .NET to decode raw telemetry protocols from Teltonika GPS hardware into actionable data for mobile enterprise clients.
I built and deployed field-service mobile modules featuring digital signature capture and real-time photographic evidence uploads, eliminating paper-based workflows.
I built a custom fleet tracking mobile app for quarry logistics. Developed natively in Android (Java) and later migrated to React Native.
