Built a Flutter-based public transport navigation app for trip planning, route discovery, and map-based transit exploration across Android and iOS. Processed 1,000+ stop and route records to support structured public transport trip planning and transit discovery workflows. Integrated OpenTripPlanner hosted on Google Cloud Run and introduced Redis caching to reduce repeated routing queries and improve trip search efficiency. Enabled offline browsing of routes, bus stops, and stop sequences using OpenStreetMap-based map flows for low-connectivity scenarios. Implemented map interaction and coordinate selection using OpenStreetMap, Nominatim, and Geolocator-based location flows while reducing reliance on paid geolocation services. Implemented local persistence for saved routes and favorite locations to improve repeat access and user convenience. Prepared and submitted production builds to Google Play and the App Store on client-managed accounts, and delivered technical documentation and fu

Architected a scalable Flutter-based warehouse and business management system supporting inventory control, stock movement, barcodes, sales history, and low-stock monitoring. Built core modules for POS, inventory tracking, barcode handling, sales history, and operational reporting. Developed business workflows for supplier management, purchase invoices, customer management, and operational reporting. Engineered the system to handle 100,000+ invoice records while maintaining usability and reliability. Built responsive and reusable UI flows for mobile and web, with a modular code structure for maintainability and future feature expansion. Added automation testing to improve reliability and support safe feature iterations.
