Blockchain developer / Software Engineer, NFT platform
Duration: 05.2020 - 07.2021
Summary:
- The NFT platform, the idea of the facilities themselves is baseball, they will also be divided into several seasons
- A platform token has been introduced (NFT can be bought only for this token)
- The token itself is algorithmically regulated, that is, an algorithm is embedded inside the smart contract that controls the supply/demand of the token on the market
Responsibilities: Blockchain development; Backend development; Maintaining and updating the smart contract code and documentation as needed; Analyzing and improving the efficiency and speed of transaction processing within the blockchain network; Setting up monitoring of AWS resources and services using AWS CloudWatch; Configuring AWS EC2 instances; Conducting comprehensive analysis of token inflation models and their impact on the ecosystem; Optimizing and securing smart contracts involves refining code efficiency, reducing costs, and fortifying against security risks; Add new feature to existing Solidity part; Solving security problems in existing contracts; Optimizing performance and gas usage; Deploy NFT on Ethereum Network; Blockchain testing and integration
Technologies: Solidity, Python, Django, Django Rest Framework, HardHat, ProxyContract, Uniswap, OpenZeppelin, Ethereum, IPFS, ERC-20, ERC-721, web3.py, Wallet integrations (Metamask, Trust), AWS(Lambda, S3, SNS, SQS, CloudWatch, CLI, ECS, EC2, etc.), PostgreSQL, Docker, Docker Compose, Github
Blockchain developer / Software Engineer, NFT project
Duration: 08.2018 - 05.2020
Summary:
- An NFT project includes a collection of 10k randomly generated characters with smart contract-side complications like referral system and price growth that depends on the number of tokens purchased
- Future plans include GameFi logic implementation
Responsibilities: Consulting on tokenomics and marketing; Complicated smart contracts structures development; Optimizing API performance and scalability through monitoring, load testing, and performance tuning; Create technical and API documentation using required standards; Participate in the entire application lifecycle, focusing on coding and debugging; Blockchain development and integration; Develop custom algorithms; Smart contracts protection
