I am a passionate Full-Stack Web Developer with 1.5+ years of hands-on experience building and maintaining real-world, production-ready web applications using modern JavaScript technologies.

My core strength lies in frontend engineering with React and Next.js, where I focus on creating clean, intuitive, and high-performance user interfaces. On the backend, I have solid experience working with Node.js and Express, designing RESTful APIs, managing authentication, and integrating databases such as MongoDB and PostgreSQL to build reliable and scalable systems.

I enjoy breaking down complex business problems into simple, maintainable solutions and collaborating closely with product requirements to deliver meaningful user experiences. I care deeply about code quality, performance, and long-term maintainability, not just making things work.

What I Strongly Believe In

• Designing efficient and secure backend architectures
• Building responsive, accessible, and user-friendly interfaces
• Following best practices, proper folder structures, and reusable components

I am highly motivated, detail-oriented, and always eager to take on new challenges that help me grow as a developer while contributing real value to the product and the team.
