I’m a Front-End Developer focused on building responsive, accessible web experiences with measurable performance improvements. In my current role at Eye4Media, I built and optimized React/Next.js web platforms, improving performance and load time by 40–50%.

I translate product needs into clean, user-focused UI, integrating features via APIs and automated workflows to speed up delivery and reduce manual effort. I also implement mobile-first and accessible design to increase mobile engagement and retention.

Before that, I worked as a self-employed Full-Stack Developer (Eddy Tech), delivering complete client web applications with React, Node.js, and TypeScript. I improved application performance by 50% and boosted SEO rankings from lower pages to top search results, while introducing testing and CI/CD pipelines to reduce regressions and streamline deployments.

I’ve also strengthened teams and product quality through mentorship during my time at Engagia, where I improved review processes and raised team productivity by 20%. My projects reflect this same mindset—shipping real value like a no-code chatbot builder for 500+ businesses, a geospatial real estate platform with 10k+ monthly listings, and an e-commerce storefront processing $150k+ annual GMV.
