Led the decoupling of a monolithic application into independent frontend and backend services, cutting deployment friction. Re-architected platform infrastructure across multiple cloud providers and built REST APIs for clinic, vendor, and patient portals.

Contributed to a high-traffic, customer-facing console where accuracy of customer-facing figures and reconciliation were critical. Aggregated data from multiple internal services to compute customer charges reliably at scale.

Inherited a half-built real-time telemetry platform and took ownership of the backend, carrying it through to production. Built the data ingestion and processing layer in collaboration with data analysts, and engineered scalable backend services on FastAPI, Redis, and PostgreSQL for a UK-based water utility.

Built developer-facing software and tooling for other engineers, alongside bespoke client engagements. Architected a multi-tenant SaaS infrastructure using Node.js and MongoDB, and led frontend architecture across React.js and Tailwind CSS.

Managed a twelve‑engineer team across web, customer, and supply‑chain squads while mentoring developers. Built an offline mapping system for low‑bandwidth users to locate nearby KOKOpoints. Created a unified frontend bridge across major frameworks. Built a microservice linking core platform, Odoo, and delivery. Improved load times via DB and frontend optimisation.
