Full-Stack Developer | React, Next.js & Node.js | Building Scalable & High-Performance Web Apps

About

I’m a full-stack developer specializing in React, Next.js, and Node.js, with hands-on experience building scalable, high-performance web applications. I love turning complex problems into simple, elegant solutions, whether it’s crafting seamless user experiences on the frontend or building robust APIs and system architectures on the backend. Over the course of multiple internships and projects, I’ve optimized performance, led end-to-end development, and collaborated with cross-functional teams in fast-paced, agile environments. My stack includes TypeScript, MongoDB, PostgreSQL, Docker, AWS, and FastAPI, among others. Curious by nature and always learning, I’m passionate about building products that blend creativity with code. If you're working on something innovative or looking to collaborate—let’s connect!
