KenyaWhat I'm looking for
I am a mechanically trained engineer turned QA/QE software developer who bridges factory operations, equipment maintenance, and software quality assurance. I apply hands-on mechanical troubleshooting and process optimization experience to deliver reliable digital and physical systems.
My background includes machine operation and repair in production environments, preventative maintenance that reduced breakdowns, and formal training in software testing and automation (manual and Cypress). I have developed web applications, written test cases, tracked defects, and collaborated with developers to validate fixes.
I mentor and train interns and junior staff, document workflows and reports, and champion safety and quality compliance. I seek roles where I can combine mechanical systems knowledge with software QA to improve product reliability and operational efficiency.
