What I'm looking for

I’m looking for a product-driven team where I can build accessible React/Next.js interfaces, optimize Core Web Vitals and load times, and take ownership of frontend architecture within an Agile/Scrum workflow.

I’m a UI Developer and Frontend Developer with 5 years of experience building, scaling, and optimizing responsive, high-performance web applications. I focus on accessible, modular, reusable frontend codebases—bringing together React.js, Next.js, JavaScript (ES6+), and Tailwind CSS to deliver clean UX and strong performance.

In my most recent role, I architected and deployed modular interfaces for enterprise-grade casino and betting platforms. I built an atomic component library that cut front-end development turnaround time by 30%, added canvas loaders and micro-interactions that improved engagement metrics by 15%, and led frontend architecture reviews while managing clean Git-based production integration.

Previously, I shipped UI components for high-traffic business applications and drove file footprint optimization and lazy rendering pipelines that reduced asset load times by 20%, strengthening Core Web Vitals performance. I also implement WCAG accessibility standards, translating high-fidelity designs into pixel-accurate, cross-device experiences while working in Agile/Scrum with Jira and Trello.
