From Angular, VueJS and React to NodeJS and Java, we treat your project like it's our own — shaping every line with the precision and pride of master craftsmen who actually care how it ends.
Full-stack engineer who loves owning a feature end to end — database model, API, and the interface people touch. I work across TypeScript, React, Angular and NodeJS/NestJS with REST and GraphQL, and I'm just as comfortable in DevOps: how code gets built, deployed and kept running. Give me a hard, tangled problem and the room to solve it properly, and I'm in my element.
Resume
Front-end developer, speaker and tech blogger. Angular and TypeScript are my home turf, and I write and speak mainly about Angular, JavaScript and deep dives into how JavaScript really works. I've helped build real products like the Seiri booking platform — and to me, clean code is simply how you respect whoever touches it next.
ResumeMarek and Miroslav met on a primary-school bench in Slovakia, and we've been building things side by side ever since. App Masons is the project our whole friendship has been pointing toward — the two of us, by day senior engineers at other companies, pouring our evenings and weekends into work we actually believe in.
Why should that matter to you? Because you won't get a rotating cast of anonymous contractors. You get two people who finish each other's sentences, who have each other's backs when a deadline bites, and who treat your project's success as personally as our own. When we say we'll craft it, we mean it — our names are on it.

Big or small, boring-but-mission-critical or brand-new and a little crazy — if it runs in a browser, we can build it. And because we live and breathe the front end, we give back to the community too.
Serious, secure, scalable systems that larger teams can rely on every single day — built the way we'd want ours built.
Got an idea nobody sells off the shelf? That's our favourite kind of problem. We shape it from a blank page into a real product.
We build and maintain open-source projects because good tools shouldn't be locked away — and the community made us who we are.
Reusable, polished UI components — in whichever framework your stack already speaks, no rewrites required.
Everyone's talking about AI. Fewer people can actually wire it into the messy reality of your business — safely, and without handing your data to someone else's cloud. That's exactly the part we love. We'll help you cut the busywork, put your own knowledge to work, and keep every byte under your roof if that's what you need.
The repetitive, soul-draining tasks — triage, data entry, routing, summaries — handed to AI so your people can do the work only humans can.
Your own documents, contracts and know-how turned into an assistant that answers in seconds — grounded in your data, with sources, not made-up guesses.
Prefer your data never to leave the building? We'll set up a local server running open-source LLMs, tuned to your hardware — full power, full privacy, no per-token bill.
Real problems, real people, real outcomes. Our flagship product, Seiri, has a full story — the rest you can visit for yourself.
Our flagship — a booking and scheduling platform for people whose real job is caring for clients, not babysitting a calendar. Trainers, salons and studios run their whole day on it: two-click reservations, automatic conflict-free scheduling, client histories and staff management, so nobody has to be glued to the phone every five minutes.
Our open-source calendar component for Angular — and the one we stand behind personally with real support. Signal-driven and Zone-less, with drag-and-drop, multiple views and a design you can bend to your app. No bloat, no per-seat tax: just the calendar you actually need, with the two of us a message away when you need a hand.
A modern e-commerce site on WordPress & WooCommerce for a Slovak car-parts supplier. Built for speed and trust — intuitive filtering and a streamlined catalog that let drivers and fleet operators find the exact part in seconds, turning frantic searches into confident sales.
A Netherlands-based agency connecting construction projects with the right people. Our mission: prove this is no cut-price labor pool, but a professional network of trusted carpenters, plumbers and electricians — and make every visitor feel that quality from the first scroll.
A modern web presence for a Slovak law firm specializing in construction and market law. We designed for one feeling above all: absolute trust. Clean, high-contrast, fast — a serious, authoritative platform that positions the firm as the leader corporate clients want in their corner.
