Words from teammates

What people I've worked with say.

I had the pleasure of working closely with Andrzej during a critical project delivery under a tight deadline. His deep expertise in Flutter, combined with his ability to quickly understand business requirements and translate them into effective technical solutions, was key to our success.

During this intense period, no challenge was too big for Andrzej. He consistently approached every obstacle with a positive attitude and a collaborative mindset, always willing to support and mentor others along the way.

He’s a strong tech lead who combines technical excellence with true team spirit. Any team would be lucky to have him!

It's been a pleasure working with Andrzej during his time as Head of Mobile. His expertise in Flutter and architectures is truly impressive, but it's his leadership skills that truly set him apart. From effectively managing a dynamic team of Flutter developers to spearheading the creation of the architecture and advanced CI/CD pipelines for our app, he's shown he can handle anything. But perhaps most importantly, he's got a knack for translating complex business requirements into actionable technical tasks. I would wholeheartedly recommend Andrzej

Andrzej embodies the qualities of both an outstanding software architect and an exceptional team leader. Working on a project designed by him was not only a pleasure but also a tremendous learning opportunity for me. Andrzej possesses a deep understanding of all the elements that make a mobile app work: clean software architecture, best programming practices, comprehensive knowledge of the underlying technology, as well as continuous integration and delivery, thorough testing, and backend integration.

Moreover, he skillfully balances short-term project needs with long-term goals, effectively minimizing tech debt while still driving the project forward rapidly. Last but not least, he has proven to be a compassionate leader who genuinely cares for his teammates' well-being and growth, always finding time to clarify doubts and assist in addressing bugs or architectural challenges.

Janusz Dziedzic

Andrzej is the best it gets. From day one, he demonstrated his great software architectural and team leadership skills.

Furthermore, he is a great mentor, and I am fortunate and grateful to work with someone of his calibre. Highly recommended.

Daniel de Oliveira

Software Engineer @ Electra Vehicles, Inc. | Flutter, Angular · Electra Vehicles, Inc.

I met Andrzej a couple of months ago and I can safely say that he made me a better developer since then.

He is definitely a technical specialist with vast knowledge of the entire mobile development industry, while also being able to write complex automation scripts for CI/CD. There was not a single issue thrown at him that he did not have a solution for.

On top of that, he is also a great leader and gained my trust immediately.

I cannot speak highly enough of Andrzej—top professional and the true definition of an expert in his field.

Paul Pasc

Senior Flutter Developer • Contractor • Freelancer

I am thrilled to recommend Andrzej, who I had the pleasure of working with. During our time working together, I was thoroughly impressed with his dedication to his work and his exceptional ability to architect and improve CI/CD processes.

As a DevOps engineer, I worked closely with Andrzej to set up the necessary CI for the Frontend. I can say with confidence that the requirements he provided were well-elaborated and thoughtfully crafted. He took great care in ensuring that the CI process was not only functional, but efficient and effective as well. Andrzej didn't stop there—he was also actively involved in identifying areas for further improvement and implementing changes on his own.

Working with Andrzej was a pleasure, as he was always approachable, collaborative, and willing to go the extra mile to ensure that our team's needs were met. I would not hesitate to work with Andrzej again, and I highly recommend him for any future roles he may pursue.

Sviatoslav Dumchenko

I'm an engineer with almost 10 years of experience and I would like to just say one sentence here:

Andrzej is the best Head of Mobile whom I have ever had the opportunity to work with.

There is not enough space in this text field to describe his advantages.
