Senior Web3/Evm/Stablecoin Full Stack Engineer

In the past 10 years I did (almost) nothing else than EVM development of our own startup idea: Ungravel Virtual Enterprises.

Travelling from chain to chain, I ended up on native stablecoin chains, s.a. ARC, STABLE and PLASMA, where the GroupWallet is very easy to understand and fully end-user-compliant. 

I worked on a stablecoin-native, truly distributed app to let anyone build a team on blockchain and to enable any informal team to emerge as a virtual company on USD. 

Virtual Enterprises can raise capital and they can invest into other groups, quite easily. This creates what we've coined "Cooperation Markets". External VC investors may bet on or invest into the entire "Ungravel Society", the sum of all virtual enterprises, as a whole, derived and pegged against market caps.

This was too much for European investors, I am too old for Y-Combinator. Today, I control a huge dApp stack that is 100% my personal property, consists of 120k lines of JavaScript and 6.5k lines of audited Solidity code.

I am still passionate, driven, unstoppable. Yet, our startup did not raise enough capital. Therefore, I apply for any coding job in this space, leveraging on what I have, hoping that it will save my customers a couple of years. On paper, I am old, in reality, I can only answer: Meet you at the market.

Lead Developer
Ungavel.com
2016 - 2026
Started to work on UNGRAVEL, right after buying the very first 2 Ethers on June, 9th 2016. Ungravel is a team building GroupWallet for virtual enterprises on stablecoin - creating a "Cooperation Market" to invest in - on stablecoin. #1 Designed and coded "CHAINSCRIPT" "ChainScript" is a x-chain abstracted middleware engine (100% JavaScript) to run mobile dApps fast and to deploy prototypes across chains rapidly. Uses a super fast crypt implementation (Noble) to load fast and highly modular on mobiles. ChainScript wraps API calls into single, atomic, highly composable commands. It is the missing link of dApp development today: a chain abstracting middleware for business logic that runs transparently across EVM chains. It does NOT rely on "Web3.js", "Ethers.js" or "Viem", it is completely independent, fast and slim. #2 Deployed Ungravel GroupWallet on 30+ different EVM compatible chains, s.a. Ethereum, BASE, Polygon, ArbitrumOne, BNBmainnet, Arc-testnet (native USDC stablecoin), STABLE.xyz mainnet (native USDT mainnet) and PLASMA mainnet. Optimism, Avalanche, Linea, Celo, Scroll, Gnosis, Blast, WorldChain, Taiko and many more. #3 Ungravel Unified Name Space covers 22+ EVM chains with a unifying Name Space: "vitalik.ethereum.eth" sends assets to "someone.on.base" across chain. This is also an additional security layer, 100% ENS compatible, highly customizable and live, today. Ungravel offers a simple front-end, mainly, this infrastructure is used to deploy and organize GroupWallets across 22 chains. #4 One-Click-Onboarding of entire groups - including account management and wallet files #5 VoiceWallet with an interactive user support. #6 PrePaid Accounts, Funding Auctions....
