AI-assisted workflows let me deliver in weeks what traditionally takes months, with full ownership of every architectural decision.

05 · Why hire me

Ex-commercial banker.
Ships the engineering.

Two years inside a UK high-street bank taught me what money, risk and regulated environments actually feel like — fraud reviews, KYC, audit trails, the cost of shipping the wrong thing. Now I bring that judgement to the build: clean architecture, honest scope, and code that survives contact with real users.
