I've redesigned legacy systems at Native Code, cutting a critical page from 120 seconds to 7 seconds and building a real-time location endpoint that sustained 1,000+ requests per second.

I design modular monoliths, performance-critical paths, and reliable backend primitives in Python, Django, FastAPI, and Go. I also extended Litestream to support encrypted SQLite replication and designed an ASTM-over-TCP protocol for bidirectional lab and medical-device communication.

For Original Software, I built a single Django backend supporting a B2C storefront, B2B reseller API, and marketing CMS for 100k+ customers. I delivered self-service reseller tooling, idempotent Celery fulfillment, and AWS deployments with Docker, Nginx, and GitHub Actions.

At Etqan Agency, I build and maintain Django and PostgreSQL backends for client products, collaborating directly with project managers and designers across time zones. My open-source work includes FluxCore and GoRing, where I focus on state synchronization, RBAC, WebSocket signaling, and distributed race-condition prevention.
