About Ambika Sadh

I am a passionate software engineer with experience in Blockchain, Agentic AI, and Python development. Since July 2022, I’ve been working at Tata Consultancy Services (TCS), contributing to PoCs using Hyperledger Fabric and Ethereum, writing smart contracts in GoLang and Solidity, and building backend APIs with Node.js.I’ve also worked on Agentic AI projects, creating Python-based agents that can read, query, and manage data from PDFs, images, and text files. My work includes integrating decentralized storage using IPFS and PostgreSQL.I enjoy solving complex problems and exploring emerging technologies in AI and blockchain. Always open to new challenges and collaborations in software engineering.

Experience

1. Software Engineer

   Tata Consultancy Services

   Jul 2022 — Present · Indore, IN

   Led multiple blockchain Proof of Concepts (PoCs) on Ethereum and Hyperledger Fabric, improving supply chain visibility for 300+ vendors and receiving client recognition for innovation. Designed and developed smart contracts in Solidity, integrating with backend APIs, resulting in 25% improvement in system efficiency. Built and deployed 15+ chaincodes in GoLang on Hyperledger Fabric using Docker-based containerized environments, ensuring high reliability and ~99% functional accuracy. Developed scalable backend APIs in Node.js to enable seamless interaction with the Fabric network for enterprise-grade applications. Integrated IPFS-based decentralized storage solutions, improving data retrieval speed by 40% and enhancing data integrity. Collaborated with cross-functional teams to deliver end-to-end blockchain and AI solutions, reducing logistical bottlenecks by 15%. Managed and optimized PostgreSQL databases and deployed applications on AWS EC2, ensuring high availability, scalability, and security. Built RAG pipelines and multi-agent AI workflows using vector databases and a multi-layer Agent Memory Framework (episodic, semantic, procedural, working memory), improving contextual accuracy and response consistency by ~45%. Designed LLM-driven document intelligence systems for PDFs, images, and text, achieving 90%+ structured data extraction accuracy, and developed enterprise chatbots with long-term memory for personalized, context-aware interactions. Developed scalable backend APIs (Python – FastAPI/Flask, Node.js) integrating LLM agents, memory services, and workflow automation, and engineered end-to-end blockchain solutions using Hyperledger Fabric, smart contracts, and IPFS, enhanced with RAG-based AI for intelligent, domain-aware systems.
