What I'm looking for

I am looking for a role that challenges my skills in AI and full-stack development, fosters collaboration, and offers opportunities for professional growth.

With over 7 years of extensive experience in the Software Development Life Cycle (SDLC), I have honed my skills in requirements analysis, system design, development, integration, deployment, and testing for various applications. My journey has led me to specialize in full-stack development, leveraging modern frameworks such as React.js, Angular, and Node.js, along with a strong command of databases like MySQL and PostgreSQL.

One of my proudest achievements was developing an AI-powered performance review system at Walmart, which utilized OpenAI’s GPT to streamline feedback collection and improve review accuracy. Additionally, I built an AI-driven HR assistant platform that significantly reduced response times for employee inquiries. My passion for AI development is evident in my hands-on experience with generative models and Retrieval-Augmented Generation (RAG) pipelines, which I have successfully implemented in various projects.
