About

I was once a software engineer, then co-founder of Roborock, and now the founder & CEO of Elecq. Although I haven’t been a coder for years, coding has always been my favorite way to relax. I build small tools to solve everyday problems, and when they happen to help others too, I love sharing them.

NozzleClogFree - Prevent clogs with regular printing

Epson says: print regularly to avoid clogs. But who remembers? NozzleClogFree auto-prints small test pages on a schedule. It keeps your inkjet clear, without wasting ink or effort. Set it once — your printer stays ready, no clogs, no surprises.
