I've built production backend systems for Overseas Network, Hyperspace AI, and Alqanun AI, spanning B2B travel bookings, decentralized AI inference, and legal research. My work combines Node.js, TypeScript, PostgreSQL, Redis, AWS, and clear API contracts.

At Overseas Network, I architected microservices and booking APIs for a multi-product travel platform, integrated four external travel providers, and built reliable order workflows with AWS Lambda, SQS, SNS, and inbox/outbox patterns. At Hyperspace AI, I helped scale a decentralized inference network that processed 400M+ requests during a peak week and created distributed reward, queueing, caching, and real-time event systems.

For Alqanun AI, I owned backend architecture for a legal assistant that retrieves across 120,000+ legal documents and delivers multilingual responses in Arabic, French, and English. I designed multi-agent RAG workflows using LangGraph.js, LangChain.js, Azure AI Search, OpenAI, and Anthropic models.

I've also led small engineering teams, reviewed code, supported deployments, documented APIs, and taken products from system design through production support. I enjoy building maintainable services that make complex integrations and asynchronous workflows dependable.
