Engineer, architect, advisor · London & remote
I’ve been writing software for 25+ years. The last few have been about production AI systems, ML platforms, and the architecture that keeps them running — in retail, supply chain, and IoT.
I work hands-on across the stack and prefer being close to the code. I’ve led teams and architectures, but my best work happens when I’m still in the editor — shaping a system, fixing what’s slow, and shipping something useful at the end of the week.
Over 25 years across freelance, permanent and contract — from start-ups and scale-ups through to large enterprise. Mostly Python, mostly on backend, data, ML and infrastructure problems. Recently the work is increasingly AI-shaped: LLM applications, retrieval over real-world knowledge, agents that call tools, and the eval and ops discipline that keeps any of it running. Alongside that, ML platform engineering and forecasting at scale.
Available for contract through my limited company, shipit.ltd.
Two pillars at the moment: production LLM systems — assistants, chatbots, multi-step agents, document/workflow automation — and ML platforms / forecasting at scale. The model itself is rarely the hardest part; most of the engineering sits around it: retrieval, tool integration, evals, observability, cost and latency, and integration with the rest of the team’s stack.
