Through Contracts / Freelance, I built and deployed full-stack applications for e-commerce, real estate, POS, and booking. I translated Figma designs into responsive Next.js and Tailwind CSS interfaces that achieved 95+ Lighthouse performance scores.
At Numeral IoT Africa, I collaborated on backend services and API design, integrating hardware IoT endpoints with cloud services. I also maintained Linux server environments and configured deployment pipelines.
I built Inkwell, a publishing platform with rich-text editing, draft recovery, real-time reader telemetry, and automated social syndication. I added custom LLM discovery endpoints and an automated testing suite using Vitest and React Testing Library.
On Faulu POS, I architected an offline-first PWA that supports checkout during network dropouts and background sync. I integrated Safaricom M-Pesa payments and webhook listeners, cutting manual reconciliation time by 90%.
