03 / AI-native, engineer-led

AI throughout the workflow.
Judgement at every step.

AI supports research, implementation, and review. I set the technical direction and check the work against the requirements of your application.

Understand & plan

Turn requirements and research into technical specifications, defined tasks, and agreed delivery checks.

Delegate & build

Coordinate Codex and development agents on defined tasks, including parallel implementation.

Connect & integrate

I build API and MCP integrations that connect applications, assistants, and business data.

Test & review

Automated testing and independent reviews check changes against the specification and the wider system.

Release with care

Controlled deployments, monitoring, and rollback planning support the change in production.

My work covers both AI-assisted software delivery and bespoke integrations that connect AI tools to your systems. We choose the approach around the application and the work it needs to do.

Beyond writing software

I build tool-connected assistants and custom MCP integrations for business operations, including work across publishing platforms, email, CRM, and task management. For clients, I offer workflow assessment and scoped implementation.

An engineer who operates businesses, too.

I founded Planet of the Vapes in 2012 and built it and Drum & Bass UK from scratch. Developing and operating these platforms gives me practical context for software that businesses depend on every day.
