Applied AI Engineer
full-stack developer & data analyst by background

I build production LLM systems and data platforms that ship — RAG pipelines, conversational agents, multi-LLM orchestration, and ingestion systems. I own the product process end-to-end: architecture, evaluation, deployment, monitoring, and cost tracking.

My background in full-stack development and data analytics — the two things that make my AI systems hold up in production.

About

Shefiu Adeyemi

I'm an AI engineer. I build systems end-to-end — RAG pipelines, multi-provider LLM orchestration, and conversational agents processing thousands of updates daily — and I own them from architecture and evaluation through deployment, monitoring, and cost tracking.

Two backgrounds make me better at it:

  • Data analytics taught me rigour. Don't trust a number until you know where it came from, measure against a baseline, and notice when a metric is quietly lying — which is most of what evaluating an LLM system really is.
  • Full-stack development taught me ownership. The model is one part of the product. I can build the API, database, interface, and deployment around it, so what I ship works for real users rather than just in a notebook.

End-to-End Ownership

Architecture, evaluation, deployment, monitoring, and cost tracking — not just the model.

Evaluated, Not Assumed

Eval sets, regression tests, and validation gates catch failures before users do.

Agents with Guardrails

Approval gates and human review keep autonomous agents accountable without slowing them down.

Cost-Aware

Per-provider, per-model LLM usage tracking so spend stays visible and predictable.
