Over the past 15+ years, I have worked with a number of programmers and participated in or led dozens of major web projects. But I’ve never met a bigger pro. Jan is Mr. Programmer. Absolute top in the field.

Roman Kučera

Chief Executive Officer, LESENSKY.CZ s.r.o.

When creating the new face of the web sites of the individual institutes of the faculty, Mr. Polzer applied and programmed the Drupal system to the original graphic design and his colleague graphically modified everything according to the assignment to our full satisfaction. Throughout the cooperation, communication was at a high professional level. We appreciate especially the willingness, helpfulness and speed.

Ing. Petr Valenta

Faculty of Electrical Engineering and Communication, BUT

Mr. Polzer is a peculiar professional who is very good to work with. He responds quickly when an unexpected problem arises. In seven years I have learned many new things thanks to him, both in working on two versions of the site and in customized training.

Petr Vendera

IT department
Bidfood Czech Republic

We have been cooperating with Mr. Polzer for many years. He has programmed not only websites but also e-shop websites for our company. We have always been very satisfied with his work. He responds quickly, we also appreciate his practical approach and ability to offer new functional solutions without having to discount our own ideas.

Mgr. Tomáš Pokorný

Company founder, ALERION s.r.o.

In 15 years of online marketing I have never met a programmer as good as Mr. Polzer. He will solve any assignment to 100% satisfaction. He responds immediately, proactively makes suggestions for improvements. I can recommend Mr. Polzer with a clear conscience, he is a great professional in his field. We thank him for his cooperation.

Ing. Tomáš Čupr, PPC Profits

CEO, Digiadvert s.r.o.

We are a small e-shop and we have a simple and clear website which has been working well for several years. If anything needs to be modified, updated or an extra tweak added, there is always a quick and workable solution. I am met with precise work and a willingness to help at all times. I am very happy for our cooperation.

Daniela Fraňková


The development of the website went smoothly and within a short timeframe. The editing and debugging was seamless and the documentation detailed. The site management was thoughtfully designed without me having to interfere. Thank you.

Mgr. Marek Piliarik, Ph.D.

Head of the Nanooptics scientific team, ÚFE

I’m fascinated by how Jan can connect Drupal modules and create something new that wasn’t there before. He doesn’t layer features on top of each other, but thinks like an architect building a cathedral out of bricks. No code gluer could ever do that. Honza really understands Drupal.
We were building a small blog, but he approached the work as responsibly and professionally as if he were coding a million-dollar contract.

Pavel Hodál


I’m glad that in preparing the new site I was referred to professionals who understand what they are doing. Jan Polzer did a great job. He was able to hear what we wanted, gave advice, communicated effectively and got the site to the shape we wanted.

P. Zdík Miroslav Jordánek, O.Praem.

Doksany Parish

Thank you for the excellent website, I am extremely satisfied. The cooperation with Jan Polzer was excellent. Fast communication, well done work and precision. This describes the overall result. Thank you!!

MUDr. Jana Kupka Maděránková


Mr. Polzer was recommended to me by my webmaster at a time when my website needed to be fundamentally changed and updated and the original webmaster was not up to the task. The response to communication was super fast and the site is problem free. I just hope that Mr. Polzer will last me until (my) grave, which is likely given our age difference.
