Profile

Four years building AI, web and mobile software, usually as the only engineer, after five years running climate and sustainable development programmes. I build AI agents that ask before they act, test what they claim, and write the docs people need to run them.

Experience

Independent contract engineer

EV Hive, an EV charging platform for a Nigerian operator · evhive.app

May 2026 to August 2026
  • Built the driver app (live on Google Play and the App Store), the operator console and the API as the only engineer.
  • Ran the first physical-charger test over OCPP 1.6J with the hardware team. Wallet top-ups count only after the server verifies the payment.

TheRadar

Product engineer

August 2022 to present
  • Deliver client products from brief to production, working directly with founders and client stakeholders on scope, architecture, release and support.
  • Audited the AI stack of a career-exploration platform: found model-routing and cost-tracking defects and modelled a 73 percent lower bill at 10,000 monthly users (USD 3,124 to 844 a month). Modelled, not measured.

Ecologistics Integrated Services

Programme and project manager

2017 to 2022
  • Delivered UNFCCC and COP-related climate programmes across Nigeria, Ghana, the UK, Spain and Egypt, with budgets up to USD 250K and teams of up to 50.
  • Designed data collection and reporting systems for a state sustainable development programme spanning 10+ government agencies and 13 local governments.

Projects

Selects

Open source, October 2026

A video clipper that explains every pick and renders nothing until you approve it. I pre-registered its eval and published the result: 0.56 against a coin flip's 0.50 on 19 videos.

Decision Room

Open source

Three agents, a validator written in code, a human approval step, 44 tests and a written autopsy of the claim that slipped through.

A government HR and performance platform

Client work, under NDA

Wrote six runbooks, about 40 release notes, a versioned maintenance procedure and a six-page trainer's guide, so the people running it don't need me in the room.
