Developed blockchain from scratch, based on substrate
I work as a Rust Developer, I have skills in PSD, Bootstrap 4, JS, CSS, HTML, Sass, Less, Rust, Substrate Developer Hub, Elrond, Near, Solidity, NodeJS, NestJS. Basic knowledge of PHP.

Has experience in testing software, games (active participation in beta tests), as well as testing site performance. Half a year of testing experience.

Performed various tasks, from the usual Landing Page layout, with cross-browser compatibility and adaptation for mobile devices, to a little help with databases (registration, balance on the site itself, etc.).

I have experience in building my own blockchain based on Polkadot-js and pure Substrate. The blockchain is already on the testnet.

Finished work on a wallet for some cryptocurrencies on the NodeJS and NestJS frameworks.
Finished work on the bridge between Realis.Network and Binance, on Rust, using the substrate-api-client and web3 libraries, and Solidity.

Developing microservises for interaction games with blockchan, creating services for messaging from bsc to substrate and substrate to bsc with http and websockets. Creating microservises using tokio, PostgresSQL, messaging from servises with NATS (RPC API), also, working with Docker and docker-compose for deploying services into Kubernetes.

Due to memory issues in Solana, I wrote my own solution for handling data in the contract. A certain number of accounts were made for one large structure. Also, I wrote my little math, because of the difference in math on Solidity and Solana.

There is little experience with Elrond (creation of a basic, ERC-20 similar, smart contract).

Wrote an analogue of Excel spreadsheets for the base of smart contracts Near. The main problem was in handling data between the smart contract and the front. The problem was solved by the fact that the data was transmitted via json.

Development of a microservice architecture for interaction between the blockchain and the game. Through the rest api, a request is made from azure, processed by the gateway, then it goes to the services, and the services are sent to the blockchain. Also, store transactions, new wallet e.t.c. in PostgreSQL, ZooKeeper and Vault.
Definitely not Blockchain
