Deep focus on API design, systems optimization, and resilient infrastructure. Active competitive programmer (ECPC participant, Codeforces, LeetCode) and CTF participant.
Architected a nine-service multi-tenant ERP with TypeScript, Express, Prisma, PostgreSQL, React, and Cloudflare Workers; enforced tenant isolation with PostgreSQL RLS and role separation, added Hyperdrive connection pooling, Grafana Cloud/Prometheus observability and alerting, Redis-backed rate limiting, and a bidirectional Shopify integration with HMAC webhooks, idempotency, inventory sync, product export, and retries.
Open source Arabic-first ERP for small and mid-sized businesses: sales, inventory, purchasing, production, fulfillment, shipping and accounting. The whole platform in one tree, so the architecture can be read end to end.
