payment tracking system, mobile SDK, file management system, digital current regulator and
hands-on experience of neural networks and machine learning. I participated in projects of
various sizes between 2-5 and 10-15 team members. My current profile is Ruby backend. My
previous area of expertise was C++ application development together with Java, Kotlin and
Objective-C minor tasks during some of my previous projects. Python is an additional knowledge
for me, which I used for personal small projects. My skills include also practical experience in
JavaScript and PHP, mostly in code refactoring and creating small components. I worked both
under Kanban and Scrum methodology in long-term projects.
I always aim for the best solution to be implemented and challenge myself to provide a high-quality
result of my work. I am able to learn and appreciate possibilities to make myself
familiar with new topics and activities, which I accept with enthusiasm.
