Data Scientist \| Backend & ML Systems \| FastAPI, RAG, LLMs, Distributed Systems

## About

I build production ML and backend systems that turn complex workflows into measurable business outcomes\. I'm a Data Scientist at Mahindra & Mahindra focused on building production\-grade ML platforms, distributed backend services, retrieval systems, and intelligent enterprise applications\. I've worked across the stack—from PostgreSQL data models and FastAPI APIs to XGBoost/TCN models, RAG pipelines, Azure OpenAI, vector search, Celery/Redis, Docker, and Kubernetes\. A few outcomes I'm particularly proud of: 1\. Reduced manual effort by 70% through distributed backend automation for enterprise budgeting workflows\. 2\. Improved retrieval precision by 20% using Azure OpenAI embeddings and Azure AI Search, while cutting manual review turnaround by 50%\. 3\. Built production systems serving 500\+ users and contributed to an estimated ₹7 Cr\+ annual business impact through intelligent budgeting recommendations\. 4\. Built a vehicle\-simulation digital twin that saves an estimated ₹4 lakh per simulation by reducing dependence on physical test iterations\. What I work on 1\. Backend Engineering: Python, FastAPI, REST APIs, WebSockets, Microservices 2\. Distributed Systems: Celery, Redis, asynchronous processing, scalable APIs 3\. AI/ML: RAG, LLMs, XGBoost, TCN, TensorFlow, NLP, Computer Vision 4\. AI Applications: Azure OpenAI, LangChain, LangGraph, vector search, knowledge graphs 5\. Data: PostgreSQL, SQLAlchemy, ETL, data modeling, Azure AI Search 6\. Cloud & MLOps: Docker, Kubernetes, Jenkins, CI/CD, Azure, GCP I enjoy working at the intersection of software engineering, machine learning, and business impact—especially when the result can be measured in time saved, cost avoided, users served, or revenue generated\. If you're building scalable ML platforms, intelligent enterprise applications, or backend systems for AI products, let's connect\.
