What I'm looking for

I’m looking for a product-focused team where I can build scalable Node/React services and ship AI workflows (RAG, LLMs) that automate real business work.

I’m a Software Development Engineer specializing in MERN-stack systems and AI-powered solutions like RAG, LLMs, and automation. I focus on building scalable backend services, optimizing APIs, and deploying reliably on AWS.

In my internship at Whuff India, I built e-commerce features (catalog, cart, checkout, orders) for 1K+ monthly users. I designed 12+ REST APIs with JWT and RBAC, optimized MongoDB queries to cut latency by ~30%, and developed an admin dashboard that reduced manual processing time by ~40%.

I also built an AI Workflow & Decision Engine (“Althea”) using MERN + RAG + OpenAI, cutting manual query effort by ~60% and reaching ~85% response relevance with integrated LLM APIs. With “Nextflow,” I built an AI workflow automation platform using AI agents, reducing manual intervention by ~50% and supporting 100+ workflows/day using async systems.
