Personal Profile

I believe in: Bridging people, technology, and purpose.

profile

I'm 44 with more than two decades in technology. After years coding in Java, PHP, Ruby and C#, I've shifted from the keyboard to the boardroom. My focus is now on connecting technology with business outcomes: partnering with senior leaders across Eastern Europe and global tech hubs to drive digital transformation, resilience and continuous improvement.

In addition to the software development I am interested in IT management. I have been introducing and leading projects utilizing agile and waterfall techniques. I've been building and working in the true Scrum teams as a Certified Scrum Master. I was delivering as a mentor, manager and engineer.

Privately I am the father of two smart boys. I’m also a former president of the Warsaw’s Rotaract Club which is a Rotary’s International program for youth.
