About Me

My name is Nandhan Varma. I'm a Computer Science and Engineering graduate from the Institute Of Aeronautical Engineering (IARE), Hyderabad, and I'm currently working as a System Engineer at TCS.

A passionate and experienced Backend Developer with 2 years of hands-on experience in Generative AI and Data Engineering. I have a proven track record of designing, building, and deploying scalable solutions on the AWS platform using AWS Bedrock, Lambda, Glue, and CloudFormation. My work involves creating robust backend systems and developing end-to-end data pipelines. I am a lifelong learner committed to continuously improving my skills and applying them to solve complex technical challenges.

My motto is: "Learn, Develop, Excel".

System Engineer

2+ yrs · Present

Tata Consultancy Services

  • Built production-ready Generative AI APIs and AWS Lambda functions using AWS Bedrock with a RAG architecture, delivering conversational AI chat and intelligent document Q&A that reduced manual data analysis time by 70% across business operations.
  • Played a key role in building a Customer Support Intelligence Platform on AWS Bedrock with a Retrieval-Augmented Generation (RAG) architecture, designing document ingestion pipelines, vector embeddings, and semantic retrieval over the knowledge base to deliver accurate, context-aware responses.
  • Developed a Text-to-SQL system powered by large language models on AWS Bedrock, enabling non-technical business users to query complex databases through natural language.
  • Architected scalable ETL pipelines using AWS Glue, Athena, and Step Functions to process terabytes of data into analytics-ready products, cutting processing time from hours to minutes and enabling real-time ML model training.
  • Managed the full application lifecycle with GitOps principles via ArgoCD and automated infrastructure deployment using AWS CloudFormation.
  • Engineered a synthetic data generation system to automatically produce production-like relational test datasets while preserving referential integrity and foreign key relationships, enabling safe ML development and testing.
