TheMovers • Full-time
Apr 2020 - Jul 2022 • 2 yrs 3 mos
Originally hired as a Java Developer to architect the core taxi-booking backend, I was promoted to Project Manager to lead a cross-functional team in delivering a full-scale logistics ecosystem. I spearheaded the strategic migration of our native applications to Flutter, successfully unifying the iOS and Android platforms into a single, high-performance codebase. Key Contributions: System Architecture: Designed complex logic for real-time driver dispatch and ride-hailing algorithms. Flutter Migration: Successfully converted legacy native apps to Flutter, reducing maintenance costs by 40%. Team Leadership: Managed developers and QA testers to ensure on-time delivery of the passenger and driver apps. Feature Integration: Implemented Google Maps SDK, GPS tracking, and secure payment gateways.
