Lead Engineer/ Developer

Deutsche Bank

Apr 2023 till date

As the blockchain SME lead to integrate with the bonds issuance of the Bank on the DLT. The Bank was apprised of the new way Asset Management methodology of keeping the assets on blockchain distributed ledger technology.

This solution of DLT is architect by me and the entire architecture layout has been presented to the management with the option of various blockchain protocols like hyperledger, DAML, sawtooth and Ethereum. After evaluation Ethereum mainnet is chosen for its wide decentralized network of nodes. There are several on-chain and off-chain processes required to keep the cloud based MongoDB databases to support this effort. The data on the Ethereum blockchain is kept in synchrony with the bank’s legacy infrastructure for bonds using oracles as smart contracts.

I have deployed the smart contracts consisting of the Digital Bond, the Cash Token, along with the DvP (Delivery vs Payment) & DeFi smart contract to enable atomic swap between the tokens. Cash Tokens are integrated with the cloud based Cash positions of the bank’s legacy system. I have designed and developed the smart contracts and led the team to code them in Hardhat, tested it on Remix. Gas optimization is done, threat modelling was done, vulnerability assessment was done internally, security audit was done internally by creating hacking smart contracts that can potentially cause loss of assets. The most important aspect of the effort was to protect the keys on a wallet, I have introduced an HSM solution along with MPC so as to enable 4Eye/6Eye on the SSO, for access and administration of these assets on the blockchain. At Deutsche Bank we will be implementing Thales/Luna HSM being supplied by Taurus. Created Multi Party Compute using JIFF for a threshold signatory functionality Laid the foundation for the banks and financial institutions to create a market place in the lines of opensea for trading in tokenized assets in the Taurus effort for the same Employed Blockcerts as a means to create certificates to bond holders using admin credentials by W3C Verifiable Credentials specification

Performed creation of sequencers to align with polygon proposed layer2 with decentralized sequencers. My efforts involved making presentation to eWPG and BaFin regulatory authorities in Europe where the bond token issuance have been done on the mainnet. Further I have been the part of the team that did the Digital Asset Custody solution for the bank customers.

July 2022 March 2023

Built trading platform that have several trading Bots that engage with multiple DeX, Binance, Kraken etc. Led the team which built the entire platform on mobile and web. Provided consultancy for building decentralized exchange for crypto included AMM for popular trading pairs, in production. Completed security audit of each of the contracts, Worked on Aave, Compound and Uniswap protocols to connect to them through Crypto Trading platform to leverage trades.

Created Perp protocol and deployed it.

The Decentralized exchange is built both on Ethereum Mainnet and on BSC using CosmoSDK for transaction on crypto pairs using DApps

Worked on Substrate for Protocol engineering for optimal blockchain using Rust for Fintech. Tech Stack: Rust, Solidity, TypeScript, Python and GoLang With Credit Suisse Bank -

Jan 2022 to July 2022

with Credit Suisse Bank The bank has implemented tokens to capitalize real estate in some of thestates with in United States using Homium tokens. II was instrumental in assessing the viability of the proposal and the architecture .

This project led by consisted of Homium tokens issued to the Lenders in consideration of loan against the home owners equity are ERC1155 tokens rendering support to both ERC20 and ERC721. Project involves integration of various technologies like Fireblocks, Kaliedo, Securitize and others. My role is to build the smart contracts and write the client code in GoLang along with others as well as to bring up the blockchain on those environments. Fireblocks is a MPC Wallet implementation, the requirement was to integrate Fireblocks to the Credit Suisse environment using solidity and nodejs. Kaliedo provided the private ethereum on clique protocol which maintained the digital assets. These digital assets were accessed through the Fireblocks using mobile app and backend Multi Party Compute wallet.

Dealt extensively with blockchain security related work in collaboration with EEA.

Uncovered unknown security vulnerabilities and code flaws in programs, validated vulnerabilities, and prepared security hardening reports.

Worked extensively on DeFi contracts
