I’m a Senior Software Developer with years of experience building scalable web applications using the MERN stack. I focus on clean UI, performance optimization, and intelligent application design, especially AI-powered features like RAG pipelines and LLM integrations.

At STFX (Feb 2023 – Present), I rebuilt and optimized a Web3 dApp frontend with Next.js and Jotai, improving rendering performance by ~30%. I also designed and implemented an internal MERN analytics dashboard monitoring 100K+ user data points in real time, and built an AI-powered search tool using a RAG-based keyword extraction pipeline.

Previously at Fiserv Inc. (Jul 2021 – Feb 2023), I implemented a micro-frontend architecture using Webpack Module Federation to support 150+ banking clients with independent deployments. I also proposed and developed a blockchain-based proof of concept for secure customer loyalty point tracking, and evaluated LLM-based document retrieval solutions to kick-start internal AI engineering initiatives.

Earlier, I delivered production web experiences as a MERN Stack Developer and Frontend Developer—handling booking and payment dashboards with 10K+ monthly transactions, and building a food delivery web application with QR-based menu access and integrated payment workflows. I bring a product-minded engineering approach that ships reliable, maintainable systems.
