Neil C.
Senior Full-Stack Developer | AI Engineer
I'm a Full-Stack Developer and Technical Team Lead with 20+ years building secure, scalable web applications for startups, SMEs, and enterprise clients — using ColdFusion, Python, PHP, JavaScript, React, and SQL. Over the past year, I've been applying that engineering foundation to AI: building with Claude, OpenAI, LangChain, and RAG pipelines. I'm not claiming to be a long-time AI specialist — I'm a senior engineer bringing real production discipline (security, scalability, maintainability, clean architecture) to a space where most practitioners are still learning to code. That combination is rare: plenty of people know the AI tools, few have 20 years of experience making software actually hold up in production. What I bring to AI projects: Senior engineering judgment: knowing when RAG is the right tool, when an agent is overkill, and how to avoid common architecture mistakes Strong integration skills — connecting AI into existing systems, databases, and workflows cleanly, not as a bolted-on demo Full-stack range to own a project end-to-end: backend, frontend, APIs, deployment 20+ years of enterprise software delivery, technical leadership, and clear communication Also available for: Legacy ColdFusion modernization and migration — a specialty area where I have deep, proven expertise (architected and led a multinational operations platform serving thousands of daily users; migrated legacy ColdFusion apps to modern, containerized MVC architectures). Why clients work with me: ✔ 20+ years of enterprise software experience ✔ Honest about where I am — strong fundamentals, growing AI specialization ✔ Clean, secure, maintainable code ✔ Clear communication, reliable delivery If you need someone who brings real engineering rigor to an AI project — not just tool familiarity — let's talk.
