What I'm looking for

I am seeking a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a Senior Full Stack Engineer with a passion for building scalable, high-performance web applications. Currently, I work at ThinkFuel Inc., where I design and implement robust services using Node.js and NestJS, while also developing intuitive user interfaces with React.js and Next.js. My experience includes leading the adoption of CI/CD pipelines, managing cloud infrastructure on AWS, and mentoring junior developers to uphold high coding standards.

Previously, I have worked with Transsion Holdings and Absa Bank Kenya, where I engineered full-stack solutions that significantly improved user experience and system efficiency. My technical expertise spans across various technologies including TypeScript, PostgreSQL, and Docker, and I have a strong background in DevOps practices, automating infrastructure provisioning with Terraform. I thrive in collaborative environments and am dedicated to delivering elegant, user-friendly solutions.
