What I'm looking for

I am seeking roles where I can build user-centered web and mobile products, mentor teams, solve performance challenges, and drive end-to-end delivery in a collaborative, product-focused environment.

I am a Senior Software Engineer focused on building high-performance web and mobile applications with strong attention to UI/UX design and usability. I design and implement end-to-end solutions, optimize application performance, and drive feature prioritization between engineering and product.

At Upview Technologies I architected scalable systems, reduced load times through performance optimizations, and implemented APIs and third-party integrations. I have hands-on experience with ReactJS, Next.js, React Native, NestJS, GraphQL and MySQL across multiple production projects.

I mentor junior developers, lead code reviews, and introduce best coding practices to improve team quality and delivery. My projects include warehouse management with QR scanning, a scalable entrepreneur platform, a cross-platform chess application, and children's learning apps.

I hold a BEng (Hons) in Software Engineering and have a track record of delivering user-friendly, visually appealing, and highly functional digital solutions that meet business goals.
