Virtual Test Rig
My master's thesis. A digital twin of a drone wing that forecasts wing-tip deflection, watches its own prediction error, and retrains and promotes a new model on its own when the predictions drift from reality.

Seven years of backend work across telecom, applied research and cyber-physical systems: REST APIs, third-party integrations, event-driven data pipelines and the databases behind them. Python most days, Postgres and Docker close by. I like systems that stay up, fail loudly, and are boring to operate.
Where I have worked and what I actually did there. Most of this code is not public.
Backend and systems integration for cyber-physical systems research, built around a drone wing digital twin. I designed an MQTT-based event-driven pipeline that joins streaming sensor data, time-series storage, ML inference and monitoring behind one API layer, containerised the whole stack, and deployed it to a Raspberry Pi with GitLab CI handling builds, tests and rollouts. A lot of the job was translating vague requirements from domain experts into something that runs.
Owned the backend for client-facing digital applications end to end, from requirements discovery through architecture, implementation, testing and deployment. The emphasis was on things that make handover painless: clear API contracts, documentation, and fewer regressions.
Built and ran telecom-facing web services and REST APIs at national scale, owned deployments, and was the third-level support when production broke. Among the systems: a personalised offers engine fed in near real-time from billing records, the authentication API in front of Vodafone Cash mobile money, and a Push USSD gateway that exposes an SMPP client as JSON over HTTP.
Operated Huawei's Service Delivery Platform underpinning MTN Ghana's network. Delivered API integrations for third-party service providers, led upgrades and server maintenance on high-availability systems, and scripted away the manual checks.
Code that is public. One is my master's thesis, the other is what I use to read the news.
