Mehul Chauhan

I am working currently working a protocol Engineer at Karnot which is a Rollup as a Service company.
I mostly code in Rust and Cairo here and some typescript.

I am working as a Blockchain Developer at Hashstack, which is a Defi protocol. During my time here we have built 2 products from scratch and one has been released and is on Mainnet and one is yet to release. I have been an active participant in the iterations and designing of the protocols.

I have written contracts in solidity with Diamond (EIP 2535 pattern), and have written extensive testcases for the same. I worked in Cairo(the first language to write provable programs) which is inspired by rust. It is the smart contract scripting language for Starknet (layer2).

I also have worked in the web3 interactions using starknet.js and Starknet react hooks in the frontend.

Previously I have worked as a freelance blockchain developer at multiple places.
I love to and regularly participate in web3 hackathons, winning some
