What I'm looking for

I'm looking for a software engineering role where I can build full-stack and AI-powered products, strengthen backend and frontend skills, and contribute to reliable, high-performance user experiences.

I've built full-stack web products and AI-powered research workflows using React, Node.js, Express, PostgreSQL, and REST APIs.

At EnDecarb.ai, I developed 10+ APIs and optimized quiz workflows across PostgreSQL and MongoDB. I also built a RAG chatbot with OpenAI APIs and Pinecone for context-aware educational document retrieval.

At Infrawave Solutions, I shipped React, Redux, Node.js, and REST API features, improved load and fetch latency by 9%, and resolved 20+ production UI and integration issues. My projects include PaperMind AI and DevTinder, where I built semantic research tools and real-time developer matching with sub-200ms messaging.
