Independently designed and built multiple end-to-end data science systems addressing real-world problems in Malawi — from financial inclusion (SmsSava, CreditIQ) to agricultural forecasting (AgriPulse) and public health data engineering (DataFlow MW). Each project followed a full MLOps lifecycle: data collection, model training, API deployment, and monitoring.

Designed and shipped full-stack web applications and a blockchain-based credential verification system (ChainVerify). Developed a production-quality REST API platform (NexAPI) with auth, rate limiting, and documentation. Gained deep practical experience in system design, API architecture, and smart contract development.

Conducted a mock network security audit of a university computing lab using VulnMapper, a custom-built vulnerability scanning tool. Identified exposed admin panels, outdated SSH daemons, and open RDP ports. Produced a structured security report with risk ratings and remediation recommendations.

A machine learning system that builds credit scores from non-traditional signals — mobile money history, airtime top-ups, and social utility patterns — for people without formal credit histories.

Predicts maize and soybean crop yields in Malawi using rainfall, soil type, and historical FAOSTAT data, with a Streamlit advisory dashboard for extension workers.

End-to-end data pipeline that ingests, cleans, and visualizes Malawi public health datasets (DHIS2) into a live analytics dashboard — updated daily via scheduled jobs.
