What I'm looking for

I’m looking for a cloud-native team where I can build LLM/RAG systems, production AI pipelines, and strong MLOps with monitoring. I want to partner with product and business teams to turn complex problems into reliable automation and analytics.

I’m an AI Engineer with 5+ years designing, building, and deploying production-grade AI/ML, Generative AI, and data platform solutions across enterprise environments. I specialize in LLM-powered RAG applications, NLP pipelines, vector search systems, scalable ML inference workflows, and data pipelines.

At Aptean India, I’ve architected cloud-native AI and data workflows using Azure Data Factory, Databricks, Spark, Azure ML, and AWS services. I built end-to-end Azure ML inference pipelines for real-time lead scoring (100K+ leads), designed RAG and LLM evaluation workflows to monitor reliability for 50+ stakeholders, and improved large-scale processing performance by optimizing Spark and Databricks workflows.

Previously at Tech Mahindra, I delivered distributed Spark/Databricks telemetry pipelines and predictive maintenance analytics, while also automating ETL with Azure Data Factory and improving model retraining and deployment speed using MLflow. As a freelance Data Scientist, I built NLP pipelines, deployed ML services, and automated data labeling workflows that reduced manual annotation effort significantly.
