My skills:
- Typescript without `any` & OOP
- High level expertise in Web3 & blockchain
- Crypto wallets architecture
- Algorithm contests experience (codeforces profile), knowledge of structures & algorithms
- App containerisation (Docker, docker-compose)

What i've been working on:
- multiple crypto wallets cores development (integrated over 20 blockchains). Interaction with smart contracts, including ERC-20, ERC-721 using web3.js.
- native libraries for react-native (made heavy crypto operations 5x faster)
- node.js backend development using express.js / nest.js, relation databases (wrote some business logic, optimised queries)
