Digital Transformation and Cloud Architecture Leader
Principal Cloud & Platform Architect · Enterprise Architect
I design licence-clean, evidence-driven platforms that run the same workloads on AWS or on-premises, from national government integrations to fintech event streams.
16+ years building enterprise systems across government, telecom, banking and IoT. I connect enterprise architecture (TOGAF, C4, DDD) with hands-on engineering: I write the decisions down, and I still read the code.

Decisions first, evidence always
Every significant choice is a written decision record. Licences are checked in CI. Static checks and live results are reported separately, and nothing is "done" until a tester signs it off. AI agents help me deliver, under human governance: no agent approves its own work.
