Security Researcher, Decentralization nerd, zk enthusiast!

Biography

Started my career as a web2 solution-oriented builder. I've helped over 20 startups to build their products and scale beyond MVP. Over the years I've gone from full-stack, DevOps to Architect roles before moving to Web3 in 2019. At first, interacted mostly with BTC and their UTXO model before moving into the EVM ecosystem.

2020 was the year I fell in love with DeFi when I started to help projects build their products by adopting the following methodology: secure by design. Through 2020, I've been active in the white-hacking community and after participating in a few confidential white-hacking operations I fell in love with security and started to offer my expertise to various projects as a security researcher.

Back in 2021 I've joined EthernautDAO's council with a goal: to bring more developers into web3, by leveraging my knowledge accumulated over the years to effectively onboard new web3 developers.

I've been an active Smart Contract developer as well, helping various confidential protocols build their smart contract architecture, emphasizing the importance of building the right architecture by combining both web2 and web3 components.

In 2022 I joined the Spearbit crew after Devconnect Amsterdam as a Security Researcher and worked alongside my colleagues to help the projects I worked with to release their products safely.

In my spare time, I started Soldeer, the first solidity-centric package manager built in Rust.
