I’m Michal Zalecki. I work as a Senior Software Engineer at Tooploox in Wrocław. Cryptography and developing smart contracts on Ethereum blockchain became my main focus although I’m still actively invested in JavaScript/TypeScript ecosystem.

I have previous experience working on projects in Python, Elixir, and Ruby. I run BlockchainPro workshops for Ethereum/dApps developers and organize a local ReactJS Wroclaw Meetup.

You can find me on GitHub, LinkedIn or Twitter.
