Python & AI Developer with hands-on experience building scalable APIs and web applications, with practical knowledge of ML, DL, NLP, and Generative AI using tools like LangChain and FastAPI.
I'm a Python AI Developer based in Mumbai, focused on building scalable APIs, web applications, and practical AI systems that solve real problems.
At WerqLabs, I built backend APIs with FastAPI for AI-based workflows, developed RAG pipelines and agent-based systems using LangChain and vector databases, and worked on backend architecture, authentication, and AI workflow automation.
My technical base spans ML, DL, NLP, and Generative AI, alongside backend engineering with Django, FastAPI, PostgreSQL, and MongoDB. I care about systems that are reliable, useful, and easy to extend.
Built a Django-based web application that lets groups collaboratively decide what movies to watch. Integrated third-party REST APIs for live movie data and designed backend logic to match preferences across group members.
Built a full-stack AI agent platform for creating and managing agents with RAG knowledge bases, database integrations, and tool connectors. Implemented retrieval with MongoDB Atlas Vector Search and pgVector, integrated Gmail tools through Google OAuth, and built a browser-based chat interface.
I'm open to freelance projects, full-time opportunities, and interesting collaborations. Whether it's building an AI-powered backend or a full product — let's talk.
