At INTROGROUP LIMITED, I focus on developing API endpoints and user-centric interfaces with Python (FastAPI), Flutter, and NextJS, contributing to digital projects aligned with the organization's goals.

At 247DoorDeliveryLimited, I built a Flutter web app integrated with FastAPI and MongoDB to automate payments and reduce delivery booking friction by 60%. I also optimized the web platform, increasing traffic by 25%, and developed an admin mobile app with package tracking and push alerts.

At Crayonics, I built FastAPI endpoints for authentication and resume parsing, implemented gamification features, and delivered an internal admin tool. At Doux Finance, I redesigned the mobile app and website and designed a centralized business dashboard.
