What I'm looking for

I'm open to remote work or relocation opportunities.

I'm a Frontend Developer with 4+ years of experience building modern, high-performance web applications using TypeScript, React, Next.js, and Astro.

Throughout my career, I've worked on projects ranging from marketing websites and educational platforms to Web3 applications. I enjoy turning complex requirements and designs into scalable, maintainable, and user-friendly solutions.

Some of my key achievements include building a reusable component library that reduced landing page development time from two weeks to three days, optimizing assets to reduce their size by an average of 60%, and improving application performance through lazy loading and bundle optimization. I've also developed automated landing page generation systems and worked on SEO, accessibility, and Core Web Vitals optimization.

I'm particularly interested in frontend architecture, performance engineering, design systems, and AI-assisted software development. I actively explore AI coding agents and workflows that help automate repetitive tasks, improve code quality, and accelerate development while maintaining consistent architecture and coding standards.

I enjoy learning new technologies, solving challenging problems, and collaborating with engineers and designers to deliver meaningful products. I'm open to opportunities where I can contribute my frontend expertise, take ownership of features, and continue growing as an engineer, especially in teams that embrace modern development practices and AI-powered workflows.
