What I'm looking for

I’m looking to build scalable, high-performance web applications with React/TypeScript, improve performance and delivery velocity, and grow into a team-lead role—working in Agile/SCRUM with strong mentorship, code review, and cross-functional collaboration.

I’m a results-driven Frontend Developer with 3+ years of experience building scalable, high-performance web applications for global brands. I’m proficient in React, Redux, TypeScript, and modern CSS frameworks, with a solid foundation in Node.js and RESTful API integration.

In my current role, I led frontend architecture using React, Redux, and Webpack, shipping 5+ production applications for international clients across beverage, fintech, aviation, and agribusiness. I reduced application load time by ~35% through code-splitting, lazy loading, and bundle optimization, and improved client Lighthouse scores; I also mentored a team of 4 developers, raising code review pass rate by 40%.

I focus on measurable velocity gains by driving component-based design systems and reusable UI libraries, cutting feature delivery time by an estimated 25%. I’ve also established code review standards and pair programming practices that reduced post-release bug reports by 30%, collaborating closely with PMs and designers in Agile/SCRUM workflows.
