Everything stays on-device with no account, cloud, or tracking, complete with a Home Screen widget and 13 languages.

About me

I'm Jakub, a software engineer, architect and founder based in the Czech Republic. I build products from the first idea to release, connecting cloud backends, native mobile apps and web frontends.

  • Building software since 2014
  • Selected projects 10
  • Companies 7

I’ve been working in software since 2014, combining freelance development with building my own products. At Blendlens, I lead product and technology, working across architecture, implementation and the details people interact with every day.

Much of my work brings the physical and digital worlds together. I co-founded Brick My World, which turns real objects and 3D files into custom LEGO® models, and Blendspace, which helps online stores show products in a customer’s own space through augmented reality. These projects bring together my interests in AR, 3D and computer vision. My master’s thesis at the University of Pardubice explored face detection and identification in raster images.

I also build smaller, focused tools. Focus Radar is my iOS app for understanding where your attention goes and deciding what to focus on next. It reflects an approach I care about: useful software with a clear purpose, no unnecessary accounts, and privacy built in. Its data stays on the device.

Client work has taken me from cloud systems and web applications to native iOS and Android apps, connected devices and product photography. My core tools include C#/.NET, Swift/SwiftUI, TypeScript/React, Kotlin and Python. I enjoy being able to follow a problem across the whole system and build the pieces it needs.

AI is part of how I work, with Claude and ChatGPT in my toolkit. The shift from Code, Eat, Sleep, Repeat to Prompt, Eat, Sleep, Repeat on this page is a nod to that. What keeps me interested is turning an idea into something people can use, and staying involved from the first technical decision through to release.
