Do you have practical experience in developing or implementing blockchain-based projects?

I have basic practical experience in developing projects using blockchain technologies in Go. Specifically, I have worked with libraries for interacting with Ethereum, created smart contracts in Solidity, and integrated them with a Go backend.

The main tasks included:

• Connecting to blockchain nodes via JSON-RPC.
• Sending and tracking transactions.
• Handling smart contract events.

An example of simple connection to an Ethereum node in Go using the go-ethereum library:

import (
    "context"
    "fmt"
    "log"

    "github.com/ethereum/go-ethereum/ethclient"
)

func main() {
    client, err := ethclient.Dial("https://mainnet.infura.io/v3/YOUR-PROJECT-ID")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println("Connected to Ethereum network")
    // Further work with the client
    _ = client
}

This experience allows understanding the specifics of working with blockchain and integrating it into Go applications.
