Architected the decentralized solution to add a self-sovereign identity layer to the internet using decentralized identifiers (DIDs) that gave users full control of their data and let them choose exactly what they want to share with other users or websites. Worked directly with Craig Sellars, co-founder of Tether, and co-wrote the whitepaper for the DID system called Multi-Dimensional Identity Protocol (MDIP), a W3C Decentralized Identifier (DID) & Verifiable Credential (VC) Standards compliant protocol that was easy to integrate with any system. Spearheaded the development of MDIP reference implementation – Keychain, and played a pivotal role in creating the Keychain & Self ID DID ecosystem that helped Self ID, Inc. raise $7.5M in funding. Pioneered the solution to derive deterministic Interplanetary Name System (IPNS) keypairs from the seed phrase (BIP-39) by modifying the libp2p-crypto library to handle an optional private key parameter that aided the users to only remember the seed phrase. Led the development along with Bitmessage maintainer, Peter Šurda to decouple Bitmessage payload signing and broadcasting from the daemon such that signing can happen entirely at client-side and daemon is used only to broadcast, supporting the app to securely communicate messages with Integrators (Attesters). Developed an initial proof of concept that gave enough confidence to the founders & investors and served as the foundation to incorporate Self ID, Inc. Rewarded with a USD 90k annual compensation for cracking the DID system implementation.

Led the development of Intraday & Temporary OverDraft feature for one of India’s largest private sector banks that automated the entire process and reduced turnaround time from 1-2 days to a few minutes by integrating Finacle and TechExcel systems into the corporate banking app. Led the development of the Goods and Services Tax Identification Number (GSTIN) feature that allowed easy linking and delinking of GSTINs with a specific bank account that reduced complexities and automated deduction of charges & fees by developing APIs on top of bank’s data.

Implemented page turning effect on the web app to give users the experience of reading a book. Architected NFT marketplace on Palm Ethereum sidechain for selling brand NFTs to game developers/publishers that can be used in the games. First blockchain developer to deploy the 1st ever ERC-721 smart contract on Palm sidechain that gave us an edge in marketing the product and making it more lucrative. Optimised the Solidity smart contracts to be compliant to NFT standards that allowed it to be easily listed in global marketplaces like OpenSea.

Built the trading engine to execute high number of buy and sell orders by maintaining a queue and order books that resulted in quick trade execution. Built 6+ cryptocurrency exchanges with support for multiple cryptocurrencies (12+) by directly connecting to full nodes and creating APIs tailored to requirements that allowed users to easily deposit the cryptocurrency of their choice.
