JMHB LTD · AI Engineer & Full-Stack Developer
Full-stack developer and solo founder, now focused on applied AI engineering. Over four years with LLMs — orchestrating agents like Claude Code and Codex across frontier models (Claude, GPT, Gemini, DeepSeek) to design, build and operate live web, mobile and API products, end to end.
Data-driven betting insights that surface positive-expected-value bets across sports markets — built on real-time odds ingestion and a fair-odds model.

Shipping production software with Claude Code, OpenAI Codex, Gemini and DeepSeek — real products, not demos.
Designing agent pipelines that plan, edit, test and verify across a live codebase — with the discipline of a working developer.
Steering frontier models against real repositories: context management, tool use, and turning model output into shipped code.
A comparative, hands-on sense of where Claude, GPT, Gemini and DeepSeek excel and where they fail — and which to reach for.
Anthropic and OpenAI APIs wired into production systems, plus familiarity with SWE benchmarks like SWE-bench.
From wireframe to deployed product: React/Next/RN, Node/FastAPI, Postgres, Linux/Nginx/Docker, CI/CD — built and operated solo.

GitHub"Build small things, well. Ship them. Maintain them. Repeat."
I'm a full-stack developer and solo founder with a BSc and a PGCE (Qualified Teacher Status), now focused on applied AI engineering — building production software with AI coding agents and frontier models.
I've independently designed, built and operated multiple live web, mobile and API products, including a published Android app and public REST APIs of my own. The teaching background still shows up daily: judging work against clear criteria is exactly the habit I apply to reviewing and steering AI-generated code.
I'm looking for applied-AI / AI engineer roles where deep hands-on agent and model experience meets the ability to ship complete, production-grade software.
Tell me about the role or what you're building. Replies usually within one working day.
