Robert Tulek

Software engineer

Summary

I am a curious and warm person, an IT professional for whom It is important that both business needs and technology challenges are taken into consideration. 

Working in an agile team(s) as a troubleshooter, team leader, scrum master and operation product owner in the last few years I was steering the team toward highly set goals. My strengths in those roles were communication skills and drawing on team members individual strengths to benefit end results of the whole team. I enjoy mentoring and I am not shy in asking for advise when I need it myself.

As an operational product owner for the verification team one of my responsibilities was to perform a early study of a feature and then drive and coach the team toward creating a verification test scope with a proper test coverage that would ensure a good quality of a feature and a final product. I had to be self-driven to initiate the work and then coach a team to perform test analysis, document test cases and automate most of them in java. My daily task was to coach a team how to apply the test strategy in the continuous delivery environment.

I had an opportunity to be part of the onsite team that supported customer with the first field release of a software product on several occasions. Problems and tasks that arose during assignments were unpredictable. That experience thought me to embrace challenges for which I could not be prepared in advance.

I strongly believe that the visualization of any data gives attractive and important insight in how complex systems behave. That helps to identify the improvements and bottlenecks. It also presents data in a way to be understood more easily.

During my work in Ericsson mainly as a system tester and troubleshooter I was focused on finding significant faults early and made sure that the products were not released before the faults were corrected. I would say that finding anomalies in the behavior of a system is my natural knack.
