At Pamodzi, I worked on an aggregator platform connecting smallholder farmers in Zambia with wholesale buyers. I researched and validated the problem, then designed the platform’s branding, wireframes, and web and mobile interfaces.
I developed the informational website and designed a relational database schema using PostgreSQL. I also built a USSD produce-listing flow with Africa’s Talking API so farmers could submit supply without smartphones.
For Pamodzi, I developed a Flutterwave payment integration and refund logic for unmet campaign demand or buyer requests. I contributed to the admin dashboard and developed a mobile app that lets buyers launch demand campaigns and make payments.
On ClauseCite, I built a retrieval-augmented generation system that answers commercial contract questions using retrieved text and cites the source for each answer. I created the contract-processing and retrieval pipeline, added safeguards against unsupported answers, and evaluated the system on an expert-labelled test set.
