During my previous job, when we were migrating to Kubernetes I couldn’t really find a GUI app that I liked, and most importantly, that could connect to multiple clusters simultaneously. We had 6 clusters and having to switch context constantly was annoying

I ended up building one [1] to use myself, shared with a few people and they loved it. I asked if they’d pay for it and to my surprise, a lot of people said yes. I’ve put up a website and a “pre-order” button with a regressive monthly discount. Sales were going up month after month, and a few months later I decided to quit my job to go all in on it.

Today, I’m averaging on ~€5k/mo from this app, but I’m still doing some part time freelancing, as well as building other products that are not as successful, but are making >€1000/mo

The latest one is open source, privacy friendly analytics for apps [2] that I’m still very actively working on. This is my current “side project” as the previous side project became my main job :)

There’s also an open source upvote site [3] that I started 6 years ago, but haven’t had much time to work on it lately, still generating $$ monthly
