Hi, I am Jan and I develop websites and web applications while surfing the world.
I cooperated with tens of businesses during my 16 years in the field and I still enjoy it.
WordPress, Magento, custom builds on Laravel and Vue, setting up Linux webservers, security, bug-fixes, APIs, SEO, tailor-made scripts. Been there, done that, got the t-shirt.
I love clean code, follow best practices and enjoy seeking most efficient ways. My work is my hobby, delivering top-class results is my pride. Check some of the testimonials below to see I am not kidding.
I have fluent English, respond within 48 hours, give estimates upfront and suggest alternative approaches where relavant. Clients get real-time dashboard of all tasks done and time spent.
Paper books, Twitter, StackOverflow, Laracasts subscription and daily coding keep me up to date. Attended a few conferences and will do more. In my free time I tinker with new ideas to expand the toolbox even further.
I've worked hard to master the tricks involved in modern web development. No matter if you want a website, an e-shop or a custom built application, I got you covered. I can program it, integrate it, host it and keep an eye on it to run nice and smooth.

We had a great experience with Jan over multiple web development projects. Highly knowledgeable, skilled, and detail-oriented, he delivered top-notch code and exceeded all deadlines. Communication was excellent, and his insightful suggestions elevated the projects. We would highly recommend Jan for any web development work.
Jan has worked with us on a plethora of various web development projects over many years. He always went above and beyond on every project, sharing his professional opinion and findings in detail so we were always fully informed. His knowledge and experience surpassed any other web developer we have worked with previously. No task was ever beyond his skill set. Highly recommended and I hope we can work together more in the future.
Jan has that rare combination of both a brilliant developer, and 100% devoted attitude. When it comes to Magento, he's probably one of the best out there. A true professional, always committed to smart and optimal solutions. Working with him has provided me with priceless peace of mind. I will definitely cooperate with him again.
I have been working with Jan Zikmund on various projects for over six years and would highly recommend him. When I started my own marketing company three years ago I approached Jan about being our web development contractor, thankfully he agreed and has been working as a crucial part of my business ever since. Jan is extremely knowledgeable and always offers the best solution for my clients. His communication is second to none and I have complete confidence in his work. I am actually not sure how I would run my business without him.
Jan has provided excellent work and is always reliable, we'd recommend him highly.
I have been working with Jan for over 3 years now and have always found his work to be exceptional. I have no trouble recommending him for web and dev projects and will continue to use his services for years to come.
Jan is fantastic to work with. He has helped me develop my website over the last year+, his code has helped implement my ideas which has increased sales. My investment in Jan's assistance has paid for itself easily.
He has always been prompt with his work, provided great documentation, his ideas on how to best implement what I'm trying to achieve are enormously beneficial. I don't need to provide every tiny detail, I can hand him a 'big picture' map and he's great at workout out the details in a smart way, without it taking forever.
I would recommend him my closest friends and colleagues. An absolute gem.
Jan is fantastic! He is an expert developer who has never let us down. Tasks are dealt with quickly and efficiently. He puts his client's interests first and always provides considered suggestions. With his guidance and skills, we have improved our Magento store which has resulted in increased conversions. We enjoy working with Jan and will be definitely hiring him in the near future. Thank you, Jan!

Development in terms of now and in terms of preparing for the future. His knowledge base is vast and his obvious interest and passion means that he is very much in touch with what is coming and what needs to be done to take up and stay at the cutting edge of business Web activity. Jan has very much contributed to the execution of our internet sales, across many platforms and in a number of countries.
I can attest to Jan being a highly committed professional with exceptionally skills and almost magical execution in relation to problem solving and prevention. He is ever reliable and reachable. Jan has rescued us from emergency outages, made daily activities run more efficiently and prepared us for expansion. More importantly Jan has endlessly sort and suggested improvements. I would say his nature is just to do it right and get it right from the start.
Highly recommend and highly skilled.
Jan is the best freelancer I've worked with. I always get back to him each time I have something that needs to get done. He's at the perfect balance between efficiency and perfectionism. I can only recommend Jan for his excellent work and his warm personality. I will hire Jan again in the future.
Jan was great. Fantastic communication and skills with Wordpress. Always eager to help us out. A pleasure to work with and we'll re-hire for future projects.
Jan has been a tremendous help and one of the main reasons my project got finally on the way. I am very glad to have found him, because he has not only over the top development skills, but is also one of the most communicative and collaborative business partners I have ever worked with. From the start on I felt very safe about the process of the project!
Jan is an excellent developer and knows Magento inside out. It will be great to work with you again. Highly recommended.
Jan has been working with us at Garnish Marketing as a Web Developer for a number of years and during the time he contracted to us he has been an enormous help. Jan has a highly technical set of skills and has an ability to problem solve where most cannot. His ability to read code and fix problems has been really very useful and if I'm honest, I will miss having such a fantastic resource on tap. Jan has a pleasant demeanor and is always very polite.
I have had the pleasure of working with Jan for the last 6 years with the full redesign of my two main websites, that required detailed custom programming and design. Every time I asked for something I thought couldn’t be done, which was also difficult, Jan found a way to do it and come in on time and budget. He has been a true asset to my online business.
We loved working with Jan, he's a real professional, always thorough and very courteous and thoughtful.
Working with Jan has been an absolute pleasure! Having worked with several IT companies previously, we can honestly say that Jan is by far the most professional & reliable we have ever used. His knowledge & work is always of the highest calibre & is always performed in a timely manner & without fuss. Nothing is ever a problem, and in suggesting possible solutions, he always takes our cost & budget into account.
Jan is also very proactive in alerting us to possible issues needing to be resolved which have saved us from bigger problems in future. His follow-up in ensuring all required tasks are successfully completed is always appreciated. We highly recommend Jan for all your IT needs. He is truly a cut above all others we have used & will easily justify his cost.
Aside from being a thoroughly pleasant man, Jan really does know his stuff and is a pleasure to work with. He listens carefully to client briefs and is happy to suggest alternative approaches to issues if he feels that it is in the best interest of the project. Jan always produced work of a high standard, on time and within budget. I have no hesitation in recommending Jan. And he can surf.
Jan is a frontend legend. Great communication, great skills and puts in big efforts when needed. Will certainly hire again.
Jan did a very nice job on the custom PHP script. The code is clean and Jan is a real professional. He communicates well and often, and is truly dedicated. Will definitely hire him again.
I was really satisfied with Jan's job on my website. He was precise, able to see all aspects of my requests and always ready to help. I'm not an easy customer to satisfy and he did it just well.
True pleasure to work with Jan. Will most definitely work with him again.
