🏢 Work experience

Software Mansion - 3 years

Software Mansion is a well-regarded, publicly listed software house based in Cracow, Poland, which is especially known for its vast contribution and presence in the React Native community.

I worked there as a software engineer, working mostly with:

• React Native (TypeScript/JavaScript)
• Swift
• Kotlin
• Python
• C++

And for the following clients:

• Amazon: Collaborated with Amazon’s US engineering team (details are under NDA).
• Starkware: Israeli blockchain scaling startup. I worked on building developer tools around Starknet blockchain. The ones I contributed to the most are:
  • starknet.swift: Starknet SDK for Swift language
  • starknet-jvm: Starknet SDK for JVM languages, written in Kotlin
  • starknet-foundry: Toolkit for developing and testing Starknet smart contracts, written in Rust.
• Mos.com: a SF-based neobank for students, that helps them finance their studies. We built the app, maintained it and made it to the third place in the US AppStore charts!

Visla.co - 1 year

During my first software engineering job I worked as a React Native engineer, and developed a mobile application for a time management SaaS.
