RANDEF is a Prague software studio. We design and build web applications, internal systems and AI automation for companies that need things to simply work.
Tell us what you needFour things, done properly. If your problem doesn't fit any of them, write anyway — we'll tell you honestly and point you somewhere better.
Customer portals, admin tools, APIs. Built to be maintained for years, not rewritten next spring.
LLM pipelines, document processing, autonomous agents. Practical automation that removes real manual work — not demos.
Making your systems talk to each other. ERP, CRM, e-commerce, payments, whatever you run.
Performance, scaling, code review. Or taking over a codebase the last vendor left behind.
No discovery workshops, no 40-page proposals.
A plain email is enough. No spec needed.
Something useful in weeks, not quarters. Fixed price, so there are no surprises.
You see progress every week. You can stop after any slice.
RANDEF is run by Ondřej Čermák, a senior software engineer. No account managers, no handoffs, no junior team hiding behind a sales deck — you talk directly to the person who designs and writes the code.
That's the whole pitch. It keeps communication short, decisions fast and quality personal.
Describe your problem in a few sentences. You'll get a reply from a human, usually within a day.
