Information about Jonas Persson


I am a degreed software engineer and a coauthor of a prototype Slack web widget for drug trials company 4G Clinical. Currently I am developing an app for financial planning that calculates the financial impacts of various life decisions.

Previously I have run an eBay book-selling business while also trading equities with different strategies, but making software work has always been my main passion.

I enjoy working out, particularly running, and my main hobby is building a track day car where I enjoy doing custom fabrication to fit performance upgrades.

I also enjoy penning safe for work jokes and posting them to instagram and taking my dog to the dog park.
