The new Slovensko v mobile app simplifies the way of logging in to government services such as the slovensko.sk portal or the electronic mailbox using a mobile key. Instead of the rather complicated use of a reader, an ID card with a chip, and appropriate software, any computer or mobile device will now suffice.

After a decline in revenue, the Magister online pharmacy store owners were looking for a new solution that would bring back a positive trend. The initial discovery phase revealed that the store was running on a decade-old framework that was no longer supported, has multiple integrations with bank payment gateways, exports for local shipping companies, a custom invoicing system, and a client communication interface.

The new eCommerce solution is built on Drupal 8 and Drupal Commerce with custom modules and enhancements. First, we created migration from a legacy database where we migrated the entire content, including order history. Then, we implemented a responsive front-end design and created a custom checkout flow for collecting information. Next, we implemented local tax rates and payment gateways. Finally, we created a custom orders admin page and an order state flow, exports for different shipping companies, an invoicing system, and a client communication interface for shop operators.

The Bus Station is a highly SEO-optimized site in the passenger transportation niche. It provides information about bus stops and potential trips that integrates four transportation providers.

As a full-stack developer, I was responsible for setting up a dedicated LAMP server, migrating the content from WordPress to Drupal 8, and creating a responsive theme and trip search feature. I also built a search widget (a small Vue.js application) that consumed data from a local JSON API, integrating four different transportation providers' APIs.

The gaming portal, Playzone.cz, is the second incarnation of the famous portal: united-games.cz. Now it has over 100,000 registered users and 350,000 readers per month.

Various Modules:
• News, articles, blog writing, and administration.
• Online television archive and live broadcasting.
• Monitoring and reserving gaming servers.
• Betting.
• A tournament module with administration, user registration, automatic match scheduling with server assignments, entering player results, and single and double elimination spiders with automatic team progression.
• A ClanBase module where ClanBase is a unique system for online gamers built and maintained by online gamers. The system's goal is to be the central communication station for teams (clans) to arrange their wars and play in ladders and competitions.

Aramark is one of the largest companies in the Czech Republic, providing catering services with more than 100 restaurants across the country. In the beginning, I was responsible for the maintenance, bug fixing, and development of new features for the intranet—the primary function was collecting the financial information from restaurants and creating reports for regional managers.

In 2012, I was put in charge of developing a new version of the intranet based on Drupal with two junior developers. We revamped the front-end and back-end to collect and report financial information, achieving a significant speedup in generating reports for managers.

My primary responsibilities, besides programming, were analyzing undocumented parts and features of an old intranet, preparing the documentation and specifications for junior programmers, code review, and deployment.

Created a portal solution for an association of real estate owners with a news section, events calendar, downloadable document templates, online store, paid membership content, and zone. Publishers are able to lock part of the content so it is shown just for certain membership types.

For the online store, we created a custom solution based on the commerce module where each product has a different pricing option depending on the membership type. Also, the products are supplied by different vendors so the invoices had to be generated with appropriate vendor billing information in PDF format and delivered via email.

The objective of the collaboration was connecting theoretical knowledge with real-life problems.
