Iterating really quickly on my new website - went through 200+ iterations in the last month or so thanks to AI-assisted tooling like OpenCode, Stitch, and Subframe.

Really enjoying coming back to the code, after I have to give up on it because the tech stacks got too complicated for a designer to follow and remain sane.

A London agency needed to scale output without adding headcount. I designed a multi-agent AI system: three specialized agents (WordPress, support, marketing), each with confidence scoring, escalation logic, and a human review gate before every output.

Not just prompts — real architecture: FastAPI + Redis Streams, Pydantic state machines, multi-channel integration (web, email, WhatsApp). Governance aligned with ISO/IEC 42001 and NIST AI RMF.

· 45% faster content delivery

· 58% faster campaign turnaround

· 41% automated support resolution — humans in control at every step

The real design challenge: defining AI behavior. Autonomy boundaries, trust signals, and when the system defers to a human.
