Message

At Grandway Technologies, I’m building KenPay, a React Native credit card payment app, with payment initiation, transaction status, receipts, and error handling integrated with backend REST APIs. I also built a RAG pipeline that retrieves relevant document context to ground LLM answers in sources.

At Ecaps, I built AEPS and DMT banking flows and integrated Mantra and Morpho fingerprint devices for customer authentication. I also shipped apps across logistics, healthcare, fintech, IoT, and Smart TV, including AtomIQ Fleet on Google Play and PulseVeda’s Bluetooth connection to Nadi Tarangini hardware.
