I love teaching people to see more.

Since 2019, I have been developing BizKitHub – the main technical platform on which we build our entire holding. It is a comprehensive digital ecosystem for business management.

BizKitHub combines CRM, e-shop, payments, invoicing, emails and automation into one system. Manage contacts, products and orders, send campaigns, issue documents and keep everything traceable.

Thanks to workflows, cron and API, you can automate processes and integrate them into your own stack. The platform is designed for long-term operation and scaling.

In 2024, I founded the private gym GymRoom with Alexander Diószeghy because we believe that a healthy body and a healthy internet belong together.

Alexander came up with the concept and built the company's physical infrastructure from start to finish. Welcome to GymRoom, a unique self-service fitness center. Enjoy working out alone, with a friend, or with a personal trainer.

We offer you not only peace and privacy for your workouts, but also guarantee a high standard of cleanliness. Reserve our space today!

Mediální platforma o kybernetické bezpečnosti, která přináší zpravodajství, rozhovory a vzdělávací obsah srozumitelně pro širší veřejnost.

Od roku 2025 pro CCTV dodávám vývoj a technické řešení platformy v úzké kooperaci s founderem Stanislavem Novotným. Cílem bylo vytvořit rychlý a stabilní publikační systém pro redakční obsah, který zvládne dlouhodobý růst, výkonnostní nároky i provozní rutinu kolem distribuce obsahu.

CCTV spojuje obsahové rubriky (zpravodajství, trendy, bezpečnost, legislativa, návody) a buduje komunitu kolem tématu kyberbezpečnosti – včetně newsletteru a návazných formátů.

V roce 2025 jsem se spoluzakladateli Richardem Pipkem a Radomírem Michalcem založil komplexní energetickou platformu pro řízení, sdílení a obchodování s elektrickou energií z decentralizovaných zdrojů.

Smart Energy Share není pouze nástroj pro sdílení přebytků – jde o plnohodnotný energetický systém, který pokrývá celý životní cyklus energie od výroby přes alokaci a vyhodnocování odchylek až po fakturaci a analytiku.

Platforma umožňuje chytré párování výrobců a odběratelů, optimalizaci spotřeby v čase, elektronické aukce energií, real-time monitoring přes IoT zařízení, správu kontraktů a detailní analytiku úspor. Funguje jako modulární SaaS řešení připravené pro domácnosti i firemní zákazníky.

Mým úkolem je návrh architektury platformy, datového modelu a klíčových aplikačních modulů. Projekt expanduje na zahraniční trhy.

Mathematicator

In 2014, I programmed the largest Czech educational portal about mathematics, Mathematicator, for my friend Marek Valášek.

For more than ten years, it has helped hundreds of thousands of students become better mathematicians and is also a commercially successful project that operates on a payment model for selling video courses.

Mathematicator is among the most visited Czech educational websites and has become an indispensable helper for high school and university students.

O2 Omnichannel

In February 2022, I was approached to rewrite the main sales application O2 Omnichannel in React.

We started programming as a team of two people, the team gradually grew, and it soon became clear to us that it wouldn't just be about technologies. Today, Omni is the main sales application that serves stores, salespeople, and call centers.

I was given a great team leader and an empathetic team of people – it's incredible that so many good people managed to meet in one place and together bring the application to production.

When the application was completed in January 2024, I needed a career break and headed towards personal development.

Within the VikiTron application, we provide these tools for free for webmasters and developers:

Czech PHP Manual

A collection of time-tested experiences and well-intentioned advice for elegant web application development.

I have written hundreds of articles about the PHP language, in which I share knowledge and experience for free. PHP is a scripting language for fast and elegant web application development.

I really love PHP because it allows you to achieve goals very quickly and maintain elegant code. I programmed my first PHP application more than 10 years ago, and since then PHP has become one of my favorite languages.

Over all those years, PHP has moved forward a lot, so on this website you will find many insights and tricks on how to solve problems elegantly. You can also read series of articles and experiences that will help significantly improve your web applications.

In 2023, I switched to Node.js and maintain PHP only for historical reasons.
