I have experience with .NET (C# and VB), Cloud (Azure and GCP), Docker, Kubernetes, some frontent (JS and TS, mainly ReactJs) and SQL & NoSQL Databases. For the blockchain experience, we (with some colleagues) tried to launch a project but we didn't do it because of the team commitment. I've been learning the web3 stack (Solidity, EthersJs, Web3Js, Hardhat..), taking some courses and reading some books and articles. I've already implemented some personal projects for learning purposes which are available on my Github profile. I've been working with Solidity (Truffle and Hardhat), ERC20,ERC721, DEX Interaction (through interfaces/routers), DAO, forking mainnet for testing... I'm currently looking for a company to give me the opportunity to start in the Web3 World professionally. Ideally I'd like to become a Smart Contracts developer but I also love fullstacking (backend oriented if possible) so, creating Smart Contracts or interacting with them would be awesome for me.

I'm senior Java developer and I want to get into blockchain

Hi, I'm Java developer with almost 6 years of professional experience. I live in Poland and I work remotely for 2 years. Now I work as blockchain developer in Future Processing. I started this new role on April 2022. So far I created small smart contract for storing footprint hash. It is implemented using Hardhat framework. My next task was to bring back old project (betting app for World Cup, this is completely internal application). This app is using Ethereum but is not deployed to mainnet - we have our own, private network. Technologies: React, Solidity, web3.js, Express.js, Truffle. Now I started learning Hyperledger Besu. My previous role in Future Processing was senior Java developer. I was working in small team (up to 4 developer and one PM) with our British client. I was responsible mostly for developing new features. I was very independent, almost every time I had to contact with client for more details about tasks. Before Future Processing I worked: - Objectivity (01.2020 - 08.2020) - Java, Spring 5, Spring Boot 2, Angular, Typescript, Postgres - Ultimo (01.2019 - 12.2020) - Java, Spring 5, Spring Boot 2, Angular, Typescript, MongoDB, Oracle DB - Sii Poland (05.2015 - 12.2019) - Java, Spring 2 - 5, Spring Boot 2, Web Sphere As you can see, my previous experience is mostly Java-oriented. Last year I decided to change career direction to blockchain developer so I started to learn this new technology. I started with reading "Mastering Bitcoin" and "Mastering Ethereum". I tried Corda (as Java-based blockchain technology), in Future Processing I'm learning Ethereum and related technologies. At home I learn Rust and Polkadot/Solana blockchains.
