Muhammad Abubakar

Full Stack AI Engineer & Automation Architect

I build AI systems that actually work in production — RAG pipelines, autonomous agents, and workflow automation that saves teams hundreds of hours.

LinkedIn Email


🧠 What I Do

I specialize in two intersecting domains:

  • AI Engineering — RAG architectures, LLM-powered agents, and multi-modal AI systems using LangChain, OpenAI, and Anthropic APIs
  • Automation Engineering — End-to-end workflow automation using n8n, Vapi, and browser automation tools that eliminate repetitive manual work

My work spans healthcare, legal/compliance, real estate, sales, and media industries.
