A remote senior full-stack or product engineering role (UTC+1 friendly) on a product team that ships to real users, ideally in health tech, fintech or AI. I want ownership from data model to UI, a team that values design docs, testing and safe deploys, and room to grow into technical leadership.

Founder and Product Engineer at Medix, building a hospital EMR and claims platform that recovered ₦203M in leaked revenue.
What I'm looking for
At Medix, I built and operate a hospital EMR, billing, and HMO-claims platform, from its data model through its user interface and payment rails. It is live at a specialist hospital and a diagnostic centre.
I restored a hospital’s 7.9 GB legacy database, reverse-engineered its ledger, and built seven detectors that recovered ₦203M in leaked revenue. They now rerun nightly against live billing data.
I also integrated two HMO payer APIs into the consultation workflow, replacing phone-based eligibility checks with live calls. The patient app I shipped in Flutter supports secure enrollment, queue updates, Paystack payments, and medication reminders.
At UpRecruit, I owned recruiter- and candidate-facing interfaces for AI matching and screening, and introduced server-side rendering. Earlier, at Traction Apps, I led a modular banking dashboard and a cross-functional team delivering a loan-application system.
