Abdul Rehman Baber — AI Engineer

AI and full-stack engineer with about four years building and operating production LLM systems. My lane is the reliability side — agents and MCP, including proactive, tool-using assistants on OpenClaw and Hermes — plus RAG, and the evals, observability and cost work that keep those systems honest, with a sharper edge in AI-search visibility (GEO).

Why you might hire me

evidence, not adjectives

Three things worth knowing.

I ship things that stay up

MapleScholar is live and I am its only engineer — paste a paper’s link, DOI or title and read it as a clean web page, then discuss it in your own language out of 70+. I also rebuilt a nonprofit’s site after it failed Google’s Ad Grants review; the resubmitted application was approved.

I keep AI systems cheap and honest

I compared ten vision models on one fixed test set, then ran the winner over 14,105 real documents for $18.15 — about a tenth of a cent each. On a live platform I found a monitoring blackout that had hidden production errors for months, and a billing error overcharging three to five times on some models.

I say so when something does not work

I spent two and a half months testing whether text on a page could be matched the way DNA sequences are. It failed, and I established why rather than quietly dropping it. The retrieval system I built answers “no match” instead of inventing one — checked against a deliberately unanswerable query across all 15 candidates.
