About this gig
Looking for a reliable full-stack web developer to bring your idea to life? Youre in the right place! I create custom web applications with secure backends, responsive frontends, and seamless API integrations tailored to your business needs.
I specialize in Node.js & Express.js for backend development, ensuring speed, scalability, and security. For data handling, I integrate powerful databases such as MySQL, MongoDB, or PostgreSQL.
