Tomáš Renčík — ANTORE
Web, mobile and desktop. One person, one architecture.
I started out on building sites, where I learned that everything stands on solid foundations and a precise plan. Today I build software: my own product family around Modulo CMS, apps for Android, iPhone, iPad, Mac and Windows, websites and e-shops. And when something on the market doesn't suit me or doesn't work, I build it myself — right away.
I build for
Own products
When something on the market didn't suit me, I built it. That is how a family of products that talk to each other was born: Modulo CMS is the mother, the others are siblings.
A modular business system and website platform on Cloudflare. Helpdesk with SLAs, CRM, invoicing, tasks, stock, e-shop, bookings and dozens of other modules — a company switches on only what it really uses. Licences, devices and apps are managed from Modulo too. Ready for Slovak e-invoicing 2027 through a digital postman.
The siblings — apps for specific work
A tablet that stays where you put it
A device locked to a single address: terminal, till or self-service kiosk. Remote management, updates and pairing by code from Modulo — no need to drive out to the site.
A mail client of my own
Mail goes straight from the server to your device — no middlemen, no third-party servers. Local AI that never sends your mail out, and post-quantum key exchange wherever the server allows it.
SFTP, FTPS and FTP transfer manager
One manager instead of three programs and a notebook full of passwords: two panes, tidy connections and passwords in the system keychain, not in a text file.
Calls and tickets in your pocket
You see who is calling before you pick up — straight from the company directory. After the call, one tap creates a ticket, even from the watch. Work and trips go straight into Modulo.
A technician's tool for receipt printers
Finds the receipt printer on the network, configures it, prints a test receipt and logs the findings of the visit. Printer setup works on its own too, without a connection to Modulo.
Solutions
One app for Android, iPhone, iPad, Mac, Windows, Linux and the web — without three teams and three budgets.
Technologies & areas
I write fast native apps on a single foundation (Tauri, Rust, Vue) and go fully native where it matters (Kotlin on Android). The apps connect to your system securely — with post-quantum key exchange wherever the server allows it.
I build web platforms that attract and convert. Click on a technology for more details.
Technologies & areas
I analyse your needs, design an intuitive UI and deliver a fast, secure, responsive solution you can manage yourself.
Under DIGITECH SK s.r.o. I offer service, installation and data integrations for POS systems.
Technologies & areas
I ensure your fiscal devices comply with regulations and that your data flows correctly between all systems.
I ensure smooth and secure operation of your digital and physical systems.
Technologies & areas
I design stable, secure network solutions and perform proactive maintenance to catch problems before they occur.
I help businesses find the right path in the digital world — analysing, planning and designing solutions that deliver results.
Technologies & areas
Every successful project starts with a quality plan. Together we'll analyse your goals and build a strategy that saves you time and money.

My own product: a tablet on the wall, a card in hand — one tap orders lunch, the kitchen sees the counts and serving runs without paper. Runs on Modulo and Kioskbase.

I migrated the original custom-PHP site entirely to Modulo: property listings with an interactive map, filtering and project details, translations, media and the client’s own admin on their Cloudflare account. Under the contract, the client also has access to the source code.

What's new
Modulo issues invoices in the Peppol (UBL) format, checks them before sending, and sends and receives them through a certified digital postman using the Slovak SAPI-SK standard. No postman of your own is needed — registering on the Financial Administration portal is enough.

The kiosk app that ran on Android tablets now has an Apple version. The Mac build is deployed, iPad and iPhone are in testing.

hypefoods.skWhy Me
With programming and artificial intelligence I push the boundaries of what's possible.
I'm not afraid of anything. The more complex the project, the more it motivates me. I combine code and AI into solutions built for the future.
My word counts and a handshake is a commitment. I complete every job down to the last detail.
From proactive monitoring to multi-layer security — I go to maximum depth to make the result perfect.
I'm available outside regular working hours and provide support whenever you need it.
My goal is to be your long-term partner. I understand your objectives and bring solutions that grow alongside you.
Studying civil engineering and working with AutoCAD and ArchiCAD taught me that every project's success depends on a perfect plan and attention to detail.
When I needed electricity at a remote cabin with no grid connection, I didn't hire a company — I learned how and built my own solar system. Every problem is an opportunity.
As a surprise for my wife I built her a fully functional piano in the browser. Technology for me isn't just work — it's a passion for creating.
I approach every challenge with calm, honesty and the belief that every setback makes us stronger. My passion is creating and solving problems.
I can adapt to a client completely — at dochadzka.online I design the whole system and the team approves it. That is exactly why I also enjoy building my own projects my way, from Modulo to Veredar. And even when I build exactly to a client's brief, there is always a piece of me in it. I don't think it works any other way.
Have a project or a question? I'd love to hear your idea and we'll craft a solution together.
