I'm a solo founder and full-stack engineer running JMHB LTD (jmhb.dev). I architect, build and ship production software single-handedly, with multiple full-stack products live in production across gaming, fintech and consumer mobile. These days I build with large language models as much as I build software — 4+ years working with LLMs, including daily hands-on use of Claude and Claude Code — and I'm as interested in evaluating model output as generating it: prompt engineering, structured evals, judging against clear standards.

• 🚀 I deliver products end-to-end — product design, full-stack development, deployment and ongoing operations
• 🧠 Full-stack across web and mobile, with applied AI, automation and real-time data pipelines
• 🎓 BSc, plus a PGCE with Qualified Teacher Status (QTS) — years spent assessing work against standards and giving structured, criteria-based feedback
• 🛠️ TypeScript-first: Next.js & React Native on the front end, Supabase / Postgres on the back
• 📫 Open to interesting work — contact@jmhb.dev
