ABOUT ME
Backend Engineer (6+ years)
Backend Engineer (6+ years)
I am a Senior Web3 Engineer at Chingari, contributing to building their NFT marketplace and auction features. I am highly skilled Blockchain and Backend Developer with extensive experience in building and managing applications and marketplaces. As a Senior Web3 Engineer at Chingari, I had played a pivotal role in developing their NFT marketplace contract in Aptos(move) chain and auction features for the Solana blockchain, and has integrated services like Livepeer and Filecoin etc.
At Aura, I led backend development for a gaming-focused NFT marketplace, architecting the product from scratch and implementing innovative features like an NFT Indexer and crypto/fiat swap payments. My technical expertise spans Node.js, Typescript, Nest.js, Aptos(move), Rust, various blockchain technologies, and both SQL and NoSQL databases, underpinned by a strong foundation in Java from her tenure at Oracle.
I have the ability to drive complex projects to completion and lead development teams effectively.

Fileverse is a Web3 file management and collaboration platform that focuses on privacy and on-chain functionality. It offers a suite of tools similar to Google Workspace and Notion but with an emphasis on decentralized storage, end-to-end encryption, and user control over their data.
I contributed in implementing a decentralized document collaboration system with real-time editing by leveraging Redis for caching user document lists and content with efficient invalidation strategies.
I contributed in building a hybrid commenting system combining WebSocket-based real-time comment broadcasting with on-chain confirmation via a custom indexing service.
Also, integrated IPFS for decentralized comment storage and used Pimlico APIs to verify on-chain comment status with a robust retry and failure handling mechanism.
Focused on performance, scalability, and data integrity by maintaining minimal storage and implementing detailed logging across verification flows.
