I have 7 years of software development experience. I have started as a native iOS developer, then switched to Flutter and in parallel have been developing my smart-contract development skills. I have learned Solidity, deployed my custom implementations for ERC-20 and ERC-721 standarts, created a contract that allows staking any ERC-20 tokens and withdraw them with reward after some period of time (the greater the period - the bigger reward). I also had some experience with Hyperledger Fabric. Now I am working on the NFT project for my Web3 portfolio.

Bitcoin Olympics Hackathon winner.
Fully developed the smart contract part of the project on Stacks (a Bitcoin layer for smart contracts) using Clarity lang.
You can find the project on devpost.
Title of the project: bitcomp-p2p-apy-btc-defi-lending
Currently creating from scratch EVM-compatible protocol based on ERC-721 and ERC-6551 using the Foundry toolkit. The project is in the active phase of development and is protected by a non-disclosure agreement, so I am limited in my ability to discuss the details of the project. However, I am open to discussing details about my knowledge, skills, and experience.

From the beginning of 2022, I independently began to study the theoretical part of blockchain technology with an immersion in the mathematical part of the issue.
In the middle of 2022, I began to develop on the Ethereum platform using the Solidity programming language and JavaScript + the React.js library. During this time, I have developed:

- Supply chain DAPP with a native token (ERC-20)
- Staking contract                              - Token vendor contract
- Gambling DApp                               - DEX contract
- State channel contract                   - Multisig wallet contract
- SVG NFT contract (ERC-721)       - Escrow contract
- Simple Betting game contract      - Batch transfers (ERC-1155)

Tech stack to develop these smart contracts and DAPPs:
Solidity, JavaScript, React.js, Web3.js, Ethers.js, Assembly
Testing:
HardHat, Truffle, Ganache, Mocha + Chai
UI:
Scaffold-eth

Additional upskilling activities:
 - OpenZeppelin standards
 - OpenZeppelin's Ethernaut challenges (smart contract security)
 
As a side task, I developed the Spot trading bot and tested it on the Binance Spot test network.
Tech stack: Python, Binance API, asyncio.
- Deepening and expanding knowledge
- Career prospects
- Decent compensation
