I was managing new and nearly all existing products’ entire life cycle,and responsible for the proper test designes (both manual and auto-matic), handling user reports, development, work estimation and taskenumeration, proposing enhancements and identifying projects’ weak-nessess. Some of the bigger tasks required application of project man-agement skills. Almost all of the development work done there is OpenSource and published on Github. Working with legacy code; integrat-ing other Open Source projects into company’s products; doing code re-views; improving development workflow; sharing knowledge with peersthrough weekly talks - these were just a couple of my responsibilities. Idesigned and proposed Nitrokey Webcrypt - an open standard, which al-lows to use FIDO-compatible devices to allow webservices’ to run cryp-tographic operations on the USB security key, instead of the users’ PChost’s memory. I have authored an OpenPGP.js modification using it.Furthemore I was auditing internal code with dynamic and static analy-sis tools, deepened cryptographic knowledge, created an in-house usedproduction tool for reproducible, safe flashing and tests of the produceddevices. I was working on Nitrokey 3 support for static passwords andone-time passwords in Rust. Finally I was developing and supportingmultiplatform GUI clients for the USB security keys based on Qt5 andElectron. Technical leader for the most of the time.

This position involved testing the latest mobile phones, its software andinteractions with the local cellular operators. It gave me a deep under-standing about the life cycle of a product, priorities of its development,and risk management, which was confirmed by earning an ISTQB Cer-tificate. Multinational environment.Here I was designing a test automation framework from the ground up,to be used for rewriting the manual tests we have into an automatic or-dinance. A C# GUI application for managing the tests was developed,with a Python driver-client executing low-level moves on the mobile de-vices. Leader in a team of 6 Test Engineers, creating automated testsuites for the requested variants.
