DOOM – Interactive Museum
3rd place, GJS Hackathon
Twenty-four hours, the brief was “interactive museum”. We built a playable DOOM-inspired exhibit, live at doom.djt-group.com. It is the reason Yord hired us afterwards.

- 24 h
- 3rd place
Czech Cyber Competition
National finalists
All three of us worked through qualifying rounds in cryptography, network security and forensics to reach the national finals.

Clipspace
Encrypted social network
An open-source social network with end-to-end encryption. Small circles instead of an algorithmic feed, no ads or tracking, keys never leave the device. Client, server and cryptography are all public, and the whole thing is self-hostable.

- E2E encryption

What we do
and who does it- Websites and web apps
- Next.js and TypeScript, from the first sketch to deployment. Fast, readable, and still workable a year later.
- Daniel · Jáchym · Tadeáš
- Software and tooling
- Not everything is a website. Encrypted clients and servers, an AI scoring pipeline, Linux CLI tools – we write the parts that run outside a browser too.
- Daniel · Jáchym · Tadeáš
- Security and audits
- Cryptography, network security, forensics. The same problems we worked through to reach the Czech Cyber Competition finals.
- Daniel · Jáchym
- Backend and infrastructure
- Servers, domains, databases, deployment. The part nobody notices until it stops.
- Jáchym
- Design and visual identity
- Interfaces, typography and branding. A design that holds together across a whole project.
