KenyaWhat I'm looking for
At Deloitte, I build and maintain enterprise web applications with React, .NET, SQL, and Azure DevOps after being promoted from QA Engineer to Software Engineer within six months.
I bring a quality-first approach shaped by designing and executing 150+ manual test cases for Deloitte's Levvia auditing platform, which supports 10,000+ users annually. I investigate production issues, verify REST APIs, and work closely with product owners, developers, QA engineers, and support teams to deliver stable, production-ready features.
Earlier, I improved a customer-facing React website's page load time by 40% at Rana Auto Selection and delivered 10+ responsive web applications as a freelance developer. I'm AWS Certified and continue building cloud- and AI-powered application skills.
