Practical tools · Jakub Rimek

Small tools for real problems.

A growing collection of practical web tools — some for factory floors, some for personal practice. Each one started as a real problem and got cleaned up enough to share.

Who built these

Made from real problems, not whiteboards

These tools come from Jakub Rimek — director of DaVinci Enterprise Services, assistant hygiene manager, and freelance developer — based in Fife, Scotland and working in two worlds at once: the office where software gets specified, and the factory floor where it gets ignored. Each tool here started as a real problem: a paper guide nobody reads, a compliance form that takes too long, a barcode that needed validating before a tray went out, or a noisy head that needed sorting. I built the tool to fix it, then cleaned it up enough to share. Custom work runs through rimek.uk.
