I ship production AI-backend systems end to end, from APIs to RAG agents.

What I'm looking for

I’m looking for a role where I can build end-to-end AI backends—Kafka microservices, FastAPI/Spring Boot APIs, and RAG/LangGraph agents—owning architecture, quality, and deployment while shipping to production.

I’m a Software Engineer focused on shipping production systems end to end—FastAPI and Spring Boot backends, Kafka event-driven microservices, React/Next.js frontends, and LLM-agent + RAG layers.

As Co-Founder at Zaylon AI, I led engineering across architecture, reviews, roadmap, and DevOps, building a multi-tenant FastAPI backend with Docker and CI/CD. I built a single LangGraph tool-calling agent with around 30 scoped tools and engineered DialectBridge for tri-lingual NLP across English, Egyptian Arabic, and Franco-Arabic.

I also hardened the backend with argon2id authentication, row-level tenant isolation across about 80 tables, and a Postgres checkout saga—bringing reliability, safety, and clean isolation to real production flows.

Beyond startups, I’ve worked as an AI Coding Expert reviewing and ranking code repositories for RLHF pipelines and building test suites for correctness, efficiency, and edge cases. My internships span Spring Boot + Redis + OAuth2/Kafka integration for core banking, and automotive cybersecurity work including CAN bus/ECU threat modeling and attack simulations in Dyna4/CARLA with ECU validation via Vector CANoe.
