In the beginning... There was teaching English.

But I began writing professionally for the countercultural Spanish tech magazine @rroba in the 90s, and then went on to be the editor/layout monkey/translator/jack-of-all-trades of the Spanish edition of "Linux Magazine – Chronicle of the Revolution".

When that closed, I also quit teaching completely and became editor-in-chief of Linux Magazine — the German one this time, but again in Spanish. I founded a publishing house with German partners in 2004. We published several tech magazines for a decade, covering free software, Linux, open hardware, and mobile technologies. I wrote scathing editorials criticising big tech, public administrations, proprietary vendors, opportunistic politicians, and everything in between. I did layout, marketed the mag to readers and advertisers, unloaded trucks full with pallets of copies, built an online subscription portal, and learned everything about the publishing business I could, just in case it would come in handy.

When the magazine market went belly up in the late 2000s and early 2010s, we held on until 2014 and then called it quits, and I recycled myself into a "communications expert" because, why not?

I started working as a marketing consultant for KDE e.V. in 2017. I work with the members of the Promo team, setting goals, managing campaigns and analysing results. I also help KDE projects optimise their communication strategies, and I copywrite and proofread their websites and blog posts.

I also run most of KDE's fundraising efforts, and consult for GNOME on the stuff I have become experienced with.

Am I expert? I guess so. I think I can answer a lot of questions of what's going on in the open source market, and can figure out what will work in a campaign, and see opportunities where they are not obvious. Either way, I'll let you be the judge of that.

Lukasz Gornicki has worked in open source since 2014 and full-time since 2020. At the AsyncAPI Initiative he is a maintainer, a member of the Technical Steering Committee, and a former Executive Director, which means he has spent years on the unglamorous side of open governance: how decisions get made, who gets to make them, and what happens when a maintainer walks away.

He also works with Open Source Europe on fiscal hosting for open source projects, which is the other end of the same problem: getting money to people who are not companies.

Earlier he drove open source development inside a corporate environment, working alongside internal OSPOs, and has spent a lot of time explaining to organisations why funding the software they depend on is not charity.
