Hi, I am

Full Stack
Developer

With a strong focus on the MERN stack, I have experience working on different web applications and possess a comprehensive understanding of building robust, scalable, and high-performance web solutions.

In addition to my core stack expertise, I have honed my skills in NestJS and Next.js Frameworks.

My journey in web development started with a strong foundation in computer science, and I've since specialized in building modern web applications using cutting-edge technologies.

I'm passionate about creating clean, efficient code and developing user-friendly interfaces that make a real impact. My experience includes working with diverse teams and delivering solutions across various business domains.

I'm particularly interested in performance optimization, scalable architecture, and implementing best practices in software development.

Beyond traditional web development, I also specialize in Generative AI and Large Language Models (LLMs), building intelligent applications, optimizing AI workflows, and implementing robust security practices in AI-driven systems.
