I enjoy turning complex ideas into practical software. My focus is on building scalable full-stack applications, integrating AI into real products, and creating tools that people actually use.

I'm a Full Stack Developer passionate about building scalable web applications and AI-powered products that solve real-world problems.

Currently, I'm building Abhyas, an AI-integrated examination platform that helps educational institutes create, evaluate, and manage exams using AI.

I enjoy designing robust backend systems, building intuitive user experiences, and integrating modern AI capabilities into production-ready applications.
