Team project. Engineered the core storage and diffing engine for a Git-inspired distributed version control system handling 10,000+ file repositories. Designed the content-addressable object store using SHA-256 and built the parallel diff computation engine with goroutines and buffered channels. Achieved 40% storage reduction through deduplication across 1,000+ commits and reduced diff computation time by 65%.

Team project. Architected and implemented backend infrastructure for a real-time chat and voice platform supporting 100+ concurrent users. Developed the Go + Fiber WebSocket signaling server, integrated Redis for caching, and containerised the backend for AWS ECS deployment. Established sub-200ms messaging latency and 99.5% uptime across 50+ simultaneous WebRTC peer connections.

Solo project. Built a scalable e-commerce backend managing 500+ products with atomic checkout workflows. Architected a 3-layer Go backend with PostgreSQL — custom JWT-based RBAC across 25+ REST endpoints. Guaranteed data consistency across 100+ concurrent transactions, reduced coupling by 60%, and kept API responses under 150ms.
