At Clinifix, I lead engineering for a healthcare technology platform, designing Node.js and PHP microservices and REST APIs for secure healthcare data processing. I introduced AES-256 encryption and role-based authentication, and integrated M-Pesa Daraja and banking APIs for digital payments.

At Reaction Wellness Ltd (WeMove), I built and launched a React Native app published on the App Store and Google Play, and developed web applications for corporate subscriptions. At Lillup, I delivered AI-powered career recommendations using the OpenAI API; through my personal project Ndunyuvendor, I built an e-commerce platform that grew to 100+ active vendors within six months of launch.
