As a key member of a 4-person Android development team, I contributed to the development and maintenance of 6 production-grade enterprise applications serving over 10 electricity distribution companies nationwide. I took full end-to-end responsibility for several applications, handling everything from architectural design and feature implementation to deployment and production support. My work focused on architecting robust applications, refactoring legacy codebases, and implementing “Offline-First” solutions. Additionally, I spearheaded the creation of a shared UI Toolkit used across all applications, optimized data synchronization for unstable network conditions, and collaborated closely with the backend team to design and improve API integration.
