Systems I have architected and deployed across fintech, AI, indoor spatial intelligence, and social impact.
An agricultural equity tokenization platform that turns Kenyan farms into on-chain investable assets. Built the Motoko backend and Rust token factory on the Internet Computer, with escrow-oriented investment flows. Live on mainnet.
An indoor navigation platform powered by a Rust positioning engine. Engineered a vector-native mapping layer and a 2.5D isometric interface to handle complex indoor spatial data where GPS fails.
A platform connecting tech volunteers with nonprofits, streamlining project management and volunteer coordination. I built the Django REST API, the Next.js dashboard, and an Android app, backed by Google Cloud Run, Cloud SQL, and Firebase.
A production campus marketplace with verified transactions, Daraja (M-Pesa) and GavaConnect payment integrations, and AI-assisted discovery, helping students do business safely and legally.
The intelligence backend behind Mshamba. A Python API for farm valuation using a discounted cash flow model, risk-adjusted crop recommendations via Sharpe ratio, and machine-learning yield prediction.
A low-code AI orchestration platform for building, deploying, and automating generative AI pipelines. Features a visual drag-and-drop builder, multi-agent workflows, and a RAG-powered knowledge base.
An AI-powered medical advisory system that helps users understand conditions, get localized recommendations, and estimate treatment costs through a price prediction model tuned to the local healthcare context.
An accessibility-first suite built with the Ability-Allies team, including a core web app for digital inclusion and an educational extension, with adaptive and assistive interfaces for students with diverse needs.
