I engineered the backend infrastructure for an Acquisition International AWARD-WINNING platform trusted by Fortune 100 companies. On Upwork I am TOP-RATED with a perfect 100% Job Success Score across every client I have worked with. I am a senior AI engineer whose code is running right now inside companies you have definitely heard of. My record includes $25 MILLION in documented client savings. I build RAG pipelines, full-stack SaaS platforms, and AI infrastructure that ships and scales. I was the founding engineer of a legal-tech SaaS platform where I designed the entire architecture from scratch: multi-tenant PostgreSQL with row-level security, LangChain RAG pipeline with HNSW-indexed pgvector search, Claude and OpenAI API integration with Pydantic output contract enforcement, and a three-tier RBAC system. In legal-tech, a single hallucination can create client liability. I built the system so it could not happen. I engineered the backend data infrastructure for LaborAI, recognized by Acquisition International as a Top Innovator in Labor Management Software in 2024 and trusted by Fortune 100 companies. I built the ingestion pipelines, idempotency controls, and query optimization layer that power real-time labor intelligence across thousands of warehouse touchpoints globally. My work reduced API latency by 40% and directly expanded the platform's throughput capacity. I have contributed production-grade tooling to Composio, an open-source AI integration framework now used by engineers worldwide.
