Muhammad S.

AI Engineer with 9+ years and $200K+ earned on Upwork. I build AI agents, AI automation pipelines, RAG chatbots, voice agents and OpenAI/Claude integrations, and run the AI operations that keep them reliable in production. I also build the mobile apps (native Swift/Kotlin or React Native) and React/Next.js/Node.js web apps around them, or add AI to the apps you already have.

I built a workflow runtime with ~26 step types (LLM calls, extraction, SQL/HTTP, knowledge queries, loops, human approval, PDF/XLSX/PPTX output), permission-aware retrieval that checks access before the search runs, and a 10-stage ingestion pipeline for ~15 source types. Self-hosted Milvus with GPU reranking cut retrieval costs and enabled on-premises installs.
