Description

Senior full-stack engineer with 30+ years of experience building and delivering complex systems across telecom, media, finance, and digital platforms. I work hands-on (Node.js, React, Flutter, PostgreSQL) while bringing CTO-level thinking where needed (7+ years overall as interim CTO).

I specialise in turning unclear ideas into working, scalable products, and in stabilising or fixing systems and teams when they become complex or unreliable. Recent work includes AI-enabled applications, integrating LLMs (OpenAI, Claude), building RAG pipelines, and implementing secure, compliant API-driven architectures.

Strong background in system integration, streaming platforms, billing systems, and mobile/web applications. Comfortable working directly with founders and stakeholders, bridging business and engineering to deliver practical results.

Best suited for startups and organisations that need senior technical ownership, fast delivery, and someone who can both build and lead without overhead.
