About Me

Yatheswar - Full Stack Developer

I’m a Software Engineer with hands-on experience across full-stack development, cloud technologies, and Generative AI. I’ve built web applications and backend systems using JavaScript, React, Node.js, PHP, Python, MySQL, and MongoDB, while also working with AWS services and big data technologies such as EMR, Hadoop, and Spark.

My experience spans both product development and cloud support, giving me exposure to building applications as well as troubleshooting real-world systems. I’m now focused on building practical AI and LLM-powered applications, exploring areas such as RAG, AI agents, APIs, and cloud-based AI solutions. I enjoy understanding a problem end-to-end and turning it into a reliable, maintainable solution.
