Experience

  • Velocity | Meaning from Motion (Development)
    https://vlcty.net/

    This is a platform which leverages machine learning and generates users insights from their motion data.

    For this project, I developed a Go-based platform API. We developed this application to handle millions of users daily, manage high loads while still having low latency, and at the same time, process hundreds of gigabytes of data every day.

    My role here wasn't limited just to the Go programming language, I also performed a great deal of system administration on AWS and because of that now I'm a certified AWS Developer.

  • Vinted App for iOS (Development)
    https://www.vinted.com/app

    This app is now probably the biggest second-hand fashion marketplace iOS app in the world with thousands of people using it every day. In this company, new features were delivered by cross-functional teams so iterations of new features were much faster due to the fact there were no bottlenecks.

    I, as a member in one of those teams, developed multiple new features as well implementing a lot of A/B testing. I also played a role in deciding which way or which feature provides the best results. During my time there, I was also continuously working with the QA team to make sure that our app was bug and crash free.

  • doo GmbH OS X App (Development)
    https://doo.net/

    When I joined the company, it was still in its startup phase and had only recently raised funding. In the beginning, I was blown away by all the constant activity and energy around me.

    My first project was providing support for the scanner peripherals in the app. After that task was completed successfully, I began working on many other areas of the application from C++ library integrations to a concurrent sync service which was based on Core Data.

    Sadly, the initial idea didn't generate enough traction and now the company has shifted gears to a different direction and our app isn't available for download anymore.

  • IDVector (Development)
    https://www.idvector.net/

    This is a VPN client application, it provides an easy way to secure your internet connection. You can buy credits via in-app purchases which later on can be used for secure connection minutes; users also can create a custom VPN with custom ingress and egress locations.

    I worked on both application versions (iOS and Android). While developing this application, I became very familiar with the VPN frameworks for the Android and iOS platforms.
