Experience

1. System Engineer

   Tata Consultancy Services

   Aug 2025 — Present · Hyderabad, IN

   As a System Engineer at TCS, I work on building and deploying AI-powered cloud solutions for enterprise clients. My role focuses on integrating AI/ML, agentic AI systems, cloud platforms, and automation to create scalable and intelligent applications. I develop AI services using LLMs, embeddings, vector databases, and RAG pipelines, and deploy them using cloud-native ML tools.I design and manage cloud infrastructure on AWS/Azure/GCP, including compute, storage, networking, CI/CD pipelines, and Infrastructure as Code. I build automation workflows using serverless functions, Docker and Kubernetes-based microservices, and event-driven architectures. I also create secure and optimized data pipelines for ETL/ELT, model training, and inference.My work involves collaborating with AI, Cloud Ops, DevOps, and product teams to deliver end-to-end AI solutions. I handle system analysis, debugging, performance optimization, and ensure cloud security through IAM, monitoring, and compliance best practices.Key achievements include designing agentic AI automation systems that reduced manual operations by up to 50%, optimizing AI inference using RAG and distributed compute to improve performance by 2–3×, and developing cloud-native AI microservices with Docker, Kubernetes, and CI/CD. I also contributed to modernizing legacy systems by migrating them to cloud-based AI architectures.Skills: LLMs, RAG, embeddings, LangChain, OpenAI APIs, AWS/Azure/GCP, Lambda/Functions, S3/Blob, EC2/AKS/GKE, Docker, Kubernetes, CI/CD, Terraform, Python, Node.js, SQL, microservices, serverless, distributed systems.
