What convinced me about this project was, above all, the team's approach. … What I value most is exactly this combination: technology + experience + knowledge of the market's real needs.

I'm happy to recommend Andrzej Klimek as an outstanding technology expert specialising in apps, automation and AI. I've had the chance to work with Andrzej and can confirm his exceptional commitment to projects. Andrzej has extensive, up-to-date knowledge of artificial intelligence and the practical ways of implementing it in applications and organisational structures. His expertise lets him design the solutions of the future effectively. What sets him apart is an exceptional drive to reach his goals and determination in getting things done. That trait made our cooperation exemplary, and every project was brought to a successful finish, to the benefit of both sides. I wholeheartedly recommend Andrzej Klimek to any company looking for a partner who can combine advanced technological knowledge with high effectiveness and reliability in delivering projects.

Andrzej made me look at the world of apps from a different angle. I already know that, thanks to our conversations, I'll move from being a user to being a creator of business solutions built on apps. Complete professionalism, knowledge and a broad perspective. I recommend him without reservation.

Assessing the potential of a start-up building AI-powered applications is a complex process that has to take many factors into account. Vision and business model, the team's experience, the technology used, competitor analysis, customer feedback, market opportunities, and the approach to ethics and sustainability - all of it matters. Andrzej has been active in the market since 2010 and has extensive experience in building AI-powered applications, which is why it's worth drawing on his experience and passion for creating apps.

Andrzej understands both business and the IT industry. It's a perfect mix. Whenever I work with Andrzej on a website, an online store or a web app, I know it will not only be polished in terms of technology and security, but also built with business goals in mind. Add to that great energy, proactivity, the ability to ask the right questions and to connect the dots quickly, and IT projects run efficiently, on budget and with a big smile. I recommend working with Andrzej to companies that know there is potential in digitalisation but have no idea where to start. Andrzej will know and will point you in the right direction.

When I look for an illustration of the word "professionalism", I picture Andrzej. Understanding, acceptance and willingness to help, while his expectations never go beyond what the other person can actually do. He can clearly define what he needs and show how to get it done. He helps you spread your wings and believes in the steps you take to reach your goal!

Andrzej is an open person with a head full of ideas! In short: professionalism and industry knowledge. It's great that we got to know each other and that our professional paths crossed. In fact, the ideas for cooperation between our projects came about on his initiative. It's clear that Andrzej approaches partnerships very professionally!
