I've been working with Marcin for over six years, and he's never let me down. He always finds a solution to any problem—not just the typical "turn your computer on and off" kind of thing. He always responds quickly and reliably to requests, which is crucial in everyday work and in emergencies. He's also able to select and advise on the right equipment for the job and propose customized solutions for the company. I wholeheartedly recommend him 😊
