Software where the provider cannot read your data.
Hudik d.o.o. is an independent software company in Osijek, Croatia, founded and run by Tibor Hudik. We build and operate end-to-end encrypted products, and we take on client work: secure systems built for you, and straight answers when you want a second opinion on a design.
What we build for ourselves
Hoodik
End-to-end encrypted cloud storage you host yourself. Files are encrypted in the browser before upload, with post-quantum key exchange. Source available and free for personal use, with free iOS, Android, and macOS apps.
hoodik.ioHoodik Cloud
The same Hoodik, run for you. A dedicated instance with its own storage bucket, EU or US region, and a full export to self-hosting whenever you want out.
hoodik.io/pricingBoth are running products with paying users, not portfolio slides. Every service below is something we already do for them.
What we can do for you
Backend engineering
APIs that hold up when the traffic arrives. Storage and billing systems a small team can run without a pager going off at night. We build them like we'll be the ones operating them, because with our own products, we are.
System architecture
Some decisions you only get to make once. Before you commit a year of engineering to a foundation, have someone who has carried systems into production map the trade-offs: what has to scale from day one, and what will hurt to change later.
Security and encryption
We set security up before the incident, not after it. Key management, client-side crypto, threat models, and hardening for systems that hold data somebody would want. We run post-quantum end-to-end encryption in production; yours can work that way too.
Design and code review
A second opinion, delivered in writing. We read your architecture or your code and tell you what we would fix first and why, in plain language. Useful before a big build, and just as useful on a system you inherited.
Tell us what you're building at hello@hudik.eu. The first conversation is free, and you talk directly to the engineer who does the work.
