Bartosz Olszewski is a Software Engineer at Lufthansa Systems Poland. He is proficient in English. Colleagues describe him as "When I joined the Lufthansa mobile app project, Bartek had already been there for quite some time, and I quickly realized just how integral he was to the team. His encyclopedic knowledge of the product was nothing short of astonishing—he always had the right answer ready, and if he didn’t, he’d research it thoroughly, consulting only the most reliable sources. Bartek’s proactive approach in refinement sessions was a lifesaver on more than one occasion. His extensive product knowledge helped us avoid potential pitfalls, and he was the one we could always count on to ensure that tasks were well-thought-out and divided in a way that made them easy to tackle. On a more personal note, Bartek and I had many in-depth conversations over the course of the project, and his openness and willingness to discuss any topic helped build a solid sense of trust and camaraderie. Knowing that I could rely on him gave me a strong sense of security within the team. In fact, Bartek inspires such confidence in me that I’d feel ready to take on even the most serious project with him as my partner. Writing this recommendation comes from the heart—Bartek is a rare gem, and any team would be lucky to have him."
