What I'm looking for

I’m looking for a role where I can build user-focused, high-performance web apps, collaborate in agile sprints, and ship reliable frontend features using React/Next.js, GraphQL, strong testing, and scalable practices.

I’m a software engineer passionate about building interactive, efficient web applications that prioritize user experience. My expertise spans TypeScript, React.js, Next.js, GraphQL (Apollo and Relay), and Python/Django, supported by UI frameworks like Material UI, xStyled, and Shadcn. I thrive in collaborative, agile environments where I help design and deliver solutions that make a real impact.

In my recent roles, I spearheaded a React.js to Next.js migration, cutting page load times by 50% and improving Core Web Vitals. I also integrated ImaliPay APIs for secure M-Pesa and bank transactions, built an Admin dashboard that reduced admin task time by 30%, and strengthened performance and reliability through code-splitting, testing (Jest/Cypress), and automation via Vercel CI/CD.
