Summary
CTO and technical leader with almost 30 years of building and scaling technology organisations, from 10-person startups to £30M operations, and a track record of turning underperforming platforms and teams into growth engines.
As turnaround CTO and board member at M3 / Doctors.net.uk our team grew revenue 200% and EBITDA by over 1500%, rebuilding a near-technologically-bankrupt software platform and the team around it to full health. As co-founding CTO of Cognitant our small team scaled an award-winning healthtech from inception to 30+ staff, serving top-10 pharma (Bayer, Bristol Myers Squibb and others) and the NHS at >99.96% uptime under NHS DTAC. Deep regulated-industry experience throughout - GDPR, ISO 27001, NHS DTAC, SaMD.
Now, through Hikari Systems, I embed AI, graph and LLM capability directly inside client engineering teams - building the knowledge into the team rather than just doing the job. Current focus: agentic architectures, RAG/GraphRAG, knowledge graphs and organisational AI adoption.
A recent hands-on output is Slater - an open-source graph engine I built in Rust: bounded-memory, Bolt-speaking, read-only ISO GQL + Cypher, with disk-native vector search, benchmarked against Neo4j, Memgraph and FalkorDB. → github.com/Hikari-Systems/slater
