What I'm looking for

I’m looking for a team where I can own end-to-end feature delivery with React/TypeScript and Node.js, integrate RESTful APIs, and drive performance optimization with clean, component-driven code—collaborating cross-functionally to ship enterprise-grade products.

I’m a Full Stack Developer with 5+ years of experience building scalable, high-performance web applications using React, TypeScript, and Node.js. I focus on clean, component-driven development and measurable performance optimization.

I’ve delivered enterprise-grade dashboards, influencer marketing platforms, and data-intensive applications. I integrate RESTful APIs, build data-driven UX, and help teams ship reliable features end to end.

I’m experienced in performance optimization techniques like code splitting, memoization, and lazy loading to improve page load times and Core Web Vitals. I also help maintain quality with Jest and Cypress testing practices, reducing production bugs.

From React/Next.js work to backend APIs with Express.js, plus hands-on Symfony/Twig template development, I enjoy turning complex designs into pixel-perfect UI components. I’ve also worked self-employed on landing pages, email templates, checkout pages, and CRM-integrated marketing flows.
