Do you take equity?

Yes and no. For our initial contract I don't take equity and most companies shouldn't give away either. However, if we continue our collaboration it's a possibility we can consider.

What's the ideal contract length for you?

Anything ranging from 1 week to 6 months. For longer contracts we can discuss it after a first successful collaboration.

What's important to you?

What technical skills do you have?

I've been practicing full-stack Javascript since 2012. My go-to front-end framework is React.js since 2016. On the back-end I have experience with Node.js and MongoDB but nowadays I'm building GraphQL API with PostgreSQL. I practice DevOps and my preferred cloud provider is Firebase with Google Cloud Platform. On mobile I've built native, hybrid and cross-platform apps with Java, Kotlin and React native. Recently I've started investing in Flutter and Dart as my main mobile toolkit. I'm interested in Go and Rust for my personal projects.
