My name is Andrei and I am a senior digital marketer. I have over 6 years of experience in digital advertising, mainly focusing on PPC advertising, Social Media Marketing, and SEO.

I am a Web3 native person.

Smart contracts security experience
- I am registered as a security researcher at Code Arena, Sherlock DeFi, and CodeHawks.
- I recently participated in my first competitive audit, where I found a High severity bug, 2 Mids and 2 Lows.
- When I am auditing I am generally using Foundry, Slither, Aderyn, Echidna, and Solodit’s database.
- I am accustomed to the most common attack vectors like reentrancy attacks, DoS, Access Control, Oracle/Price Manipulation, Flash Loans, Mishandling of ETH, Weak Randomness, Storage Collision, and MEV to name some.
- I know how to write a professional findings report.
- I’m accustomed to smart contract development patterns like CEI and FREI-PI.
- I have experience writing Fuzz tests and Invariant tests.

Blockchain development experience
I deployed smart contracts on 20+ blockchains. Everything that you can find inside Chainstack’s docs (https://docs.chainstack.com/docs/protocols-tutorials) from Ethereum to Polygon, zkSync, Aptos, Solana, StarkNet, Fantom, etc.

Worthy mention:
- Decentralized investments ecosystem based on NFTs. The project involves 3 contracts.
1 - WealthWarriors, an NFT collection that uses Chainlink's VRF when minting NFTs in order to ensure a fair distribution. The NFTs have different rarities which will impact the allocation during IDOs in the 2nd contract.

2 - DemoIdo contract. It checks a user's balance and allows him to whitelist himself to participate in an IDO as long as he holds at least 1 NFT from the WealthWarriors collection. Depending on the number of NFTs a user holds, and their rarities, the allocation will increase/decrease. The more NFTs you have and the rarer they are, the more you can invest.

3 - ToTheMoonToken -- a dummy ERC20 token contract, that looks at the amounts invested by each participant during the IDO phase, and has a mechanism to distribute the tokens at TGE based on that. I also added a tax there, because I wanted the dev to win something when people trade his token. You can try the contracts below on the Sepolia Testnet.
