About Me

Professional summary

Full-Stack Software Engineer with 4+ years building web applications end to end — responsive front-ends, scalable APIs, robust databases, and cloud deployments. Experienced across healthcare, agriculture, and enterprise systems, having delivered ERP platforms, traceability systems, and laboratory information management software.

Comfortable across React and Angular on the front-end; Node.js, Python, and Java (Spring Boot) on the back-end; with PostgreSQL, MySQL, and MongoDB, deployed on AWS and Azure using Docker and Kubernetes. I deliver clean, testable, maintainable code and collaborate closely with cross-functional teams.

Currently pursuing an MSc in Artificial Intelligence at The Open University of Kenya, deepening my expertise in machine learning, deep learning, and NLP.
