Principal Full Stack Engineer

I am a seasoned Full-Stack Engineer with deep expertise across the entire software development lifecycle, specializing in web, AI/ML, and blockchain technologies. On the frontend, I craft high-performance, user-friendly applications using React, Next.js, Angular, TypeScript, and TailwindCSS. On the backend, I architect scalable systems with Node.js, Nest.js, Express.js, and Python (FastAPI), alongside advanced AI/ML solutions powered by TensorFlow and Keras. My database experience spans PostgreSQL, MongoDB, MySQL, and vector DBs like Pinecone and ChromaDB.

In blockchain, I've designed and deployed smart contracts (ERC20, ERC721, ERC1155), integrated dApps with Ethers.js and Web3.js, and delivered NFT-enabled platforms using Truffle and Remix on Ethereum testnets. I am AWS-certified, with proven DevOps skills in Docker, Kubernetes, CI/CD (GitHub Actions, Jenkins), and Infrastructure as Code, enabling secure, cloud-native deployments. Known for bridging innovation with reliability, I thrive in agile, cross-functional teams to deliver impactful, production-ready solutions at scale.
