Resume

Eleven years, one direction — deeper into the stack.

I started as a PHP developer in 2015 and moved steadily down the stack — web scrapers and Flask microservices, then CNN image categorisation, then chatbots, and now multi-agent LLM systems. Every layer left a fingerprint on how I build.

    Lead Data Scientist

    HP Inc. · Gurugram

    Leading a team of five engineers building an internal multi-agent chatbot that connects Sales and Marketing to the company's own data warehouses in natural language. Tool-augmented agents plan, call SQL and Python, reason over warehouse-scale data, return charts and explain how they got there. Also shipping a B2B sales-intelligence platform that vectorises third-party signals on enterprise accounts and serves a multi-agent reasoning layer that proposes outreach plays.

    Senior Data Scientist

    R-Systems (a Blackstone company) · Noida

    Built a talking-head Avatar Video Chatbot end to end — Stable Diffusion XL and GFP-GAN for face generation, BARK for voice, Llama 2 with LangChain and PEFT/LoRA for the conversational core. Shipped the Tunein voice assistant on Skullcandy's Skull-iQ platform (Rasa NLU, Dialogflow, Flask, Docker on GKE). Designed a custom diffusion image-generation pipeline from scratch on UNet2D + DDPM, and led a Dataiku CI/CD migration that lifted team productivity by 20%.
