About Me

Passionate
about crafting
great software

Full-stack developer who loves building things that are fast, reliable, and polished. From low-level systems in Go to React interfaces - I care about both the engineering underneath and the experience on top.

I've shipped competitive platforms used by 200+ learners, built UI component libraries that cut integration time by 30%, written HTTP servers from scratch, and designed real-time systems that hold under load. I'm demanding about quality at every layer.

Engineering Philosophy

Not just features -
systems that last

I'm demanding about what happens after the code ships: latency under load, what breaks when an auth token is forged, whether two goroutines race on shared state. Performance, security and reliability are design constraints - not afterthoughts.

Concurrency & Low-level
Goroutines, channels & mutexes in Go. TCP chat server handling 10+ simultaneous clients, UDP game server at 50+ fps - single-process, zero data races.
goroutines channels UDP / TCP sync.Mutex
Security
bcrypt password hashing, session & cookie management, context-scoped HTTP calls with hard timeouts. I think adversarially before I ship.
bcrypt sessions OWASP
Real-time Systems
WebSocket servers in Go with pub/sub broadcast, throttle & debounce on the client, message history pagination - built for high-frequency events.
websockets pub/sub gorilla/ws
Algorithms
Implemented multi-path shortest-route optimisation (lem-in) to move N ants through a colony graph in the minimum number of turns.
graph theory pathfinding BFS/DFS
Containerisation
Multi-service Docker architectures - separate images for backend & frontend, exposed ports, DB migrations on startup, full reproducibility.
docker migrations sqlite3
Reliability Under Load
Built an HTTP/1.1 server in Rust (epoll, single-thread, non-blocking I/O) that holds 99.5% availability under siege stress testing. Code that never crashes.
