Achievements
A selected list of projects and achievements
Blockchains, Smart Contracts, Decentralized Finance and Dapps
- Instrumental in creating the DEXTF protocol model for Decentralized Asset Management, from the design stage, to mainnet deployment on the Ethereum blockchain. The project was able to receive two separate grants from the Singapore MAS resulting in funding of more than 400,000 USD.
- Instrumental in the design of the tokenomics, and deployed the DEXTF token on the mainnet. The DEXTF token at one point was traded at 4USD with a total supply of 100,000,000.
- Deployed the UMA -DEXTF-$ which provided weekly income in excess of 10,000 USD/week.
- Developed a DEXTF prototype on the Algorand blockchain that resulted in a grant of 150,000 USD.
- Currently working on various DeFi projects, including the use of the blockchain-independent Reach Dapp language which ensures formal verification of smart contracts.
Data Science, Quantitative Finance, And Risk Management
- Created a model to measure the market risk of a centralized/decentralized exchange with focus on the long/short positions.
- Experienced risk-management quant with a focus on numerical risk simulations.
- Created original quantitative models to numerically compute risk measures, risk contributions, stress tests, sensitivity analysis, and liquidity risk (liquidity score and market impact).
- Oversaw the software implementation of quantitative models in software (StatPro Risk Factory) and their link with market data.
- Designed and implemented the risk engine currently used by the StatPro analytics (StatPro Risk API used by Revolution).
- Created several robot-trading portfolio to take advantage of certain statistical-arbitrage opportunities in the crypto-currency markets.
- Revised and improved a model for the computation of the time-to-liquidate and the market impact of bonds, in compliance with US regulation.
