Custom software and app development

For companies that have outgrown their spreadsheets. The app runs in the browser, so nobody installs anything, and it works on the office computer and on a phone in the field. The best example is the Polákstav system: it started as an automated Google Sheet and now has ten modules, from attendance to payroll. It fits when you have a process of your own that off-the-shelf software misses, or you pay for several tools that do not talk to each other.

I have worked with React Native since 2018: the apps for Czech floorball, ice hockey and football were used by tens of thousands of people, and an investment app had Face ID sign-in and live portfolio charts. I also handle the App Store and Google Play releases. If a web app on the phone is enough for your case, I will tell you at the start.

For companies that retype the same data between spreadsheets, e-mails and systems. I connect the tools you already use and let calculations, reports and alerts run on their own. If Google Sheets is enough for you, I automate it, as I did for Polákstav: three contract types, attendance, wages and costs per site in one spreadsheet built for people with no technical background. When a spreadsheet hits its limits, a web app grows out of it naturally.

For construction, installation, trade and field service companies. You can start straight away with my ready-made product Evidenka, set up in your colours and with your logo within 48 hours, and try it free for 7 days. If your process needs something a ready-made system cannot do, I build it custom, as for the construction firm Polákstav, where ten modules run every day.

For digital agencies, studios and product teams that need a senior frontend developer. I build interfaces in React, Next.js and React Native, animation with GSAP, Reanimated and Lottie, and 3D in WebGL. I can work under your brand while the client talks to you, or directly in your repository and your process. My experience comes from teams at J&T Banka, Škoda Auto and Groupon, and this website is itself a showcase of animation and 3D.
