Fullstack Developer
React · Next.js · Node.js · TypeScript

Building responsive and modern web interfaces with a strict focus on User Experience, Performance, Web Accessibility (A11y), and Clean Architecture.

I am a Fullstack Developer with a primary focus on building polished, user-centric web applications using React, Next.js, and TypeScript.

While I am capable of architecting entire applications from the database up, I am currently dedicating my expertise to the Frontend layer. My background in backend development (Node.js, Express.js, MongoDB, Prisma, PostgreSQL) gives me a unique edge — I don't just build UIs; I build "API-aware" interfaces that are robust, scalable, and easy for backend teams to integrate with.

Currently deepening my expertise in Web Accessibility (A11y/ARIA), SEO Optimization, Feature-Driven Architectural Design, and Advanced Server Components Patterns.

• Scaled folder maintainability by implementing Feature-Driven Architecture for precise domain isolation.
• Reached high-end SEO and Accessibility (A11y) scores via semantic layouts, programmatic header-section mapping, strict screen-reader handling (aria-label, aria-hidden), and native HTML <dialog> components.
