A note from the person who built this
I'd rather run two products I actually care about than a dozen I don't. Everything below is because of that.
Why one job

I build one thing, and build it well

TestKit exists to answer one question: are we ready to ship? TaleUs exists to answer another: what happens next? I don't bolt features onto either just because a trend says to.

Why these two

I build what I'd actually use

Both started because the alternatives frustrated me enough to fix them myself. If a feature doesn't make sense to the person actually testing, or actually writing, it doesn't ship.

How I run it

I answer to customers, not investors

No venture rounds, no growth-at-all-costs roadmap. Pricing stays honest, free tiers stay free, and I build things meant to run for years, not to flip.
