Track Record
Experience
Self-directed research, real builds, and applied fieldwork — framed by what was built, what impact it had, and what was learned.
Data Science Intern
Self-Directed Research & Build · Mzuzu, Malawi
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.
- Built and deployed 4 data science systems end-to-end
- Applied ML models (XGBoost, NLP/regex, gradient boosting) to African-context data
- Containerized services with Docker and served models via FastAPI
- Used SHAP for model explainability and bias auditing
Full-Stack & Blockchain Developer
Self-Directed Projects · Mzuzu, Malawi
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.
- Deployed smart contracts on Ethereum Sepolia testnet using Solidity + Hardhat
- Built NexAPI: a full Node.js API platform with JWT auth, RBAC, Redis rate-limiting
- Integrated IPFS for decentralized storage in ChainVerify
- Designed React admin panels for user/content management
Security Researcher (Ethical Hacking)
Mzuzu University Lab — Mock Audit · Mzuzu, Malawi
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 Identified exposed admin panels, outdated SSH daemons, and open RDP ports.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.
- Identified 3 critical security misconfigurations in a live lab environment
- Built the scanning tool (VulnMapper) from scratch using Python + Nmap
- Generated professional PDF security reports with CVE references
- Presented findings and remediation plan to lab administrators
All experience listed represents real projects designed, built, and shipped independently — not coursework exercises. Each has a corresponding project page with technical depth and impact documentation.
