About Joshua Chen

Independent developer. I write about buying, rescuing, and building small Apps / micro-SaaS — and I take on the work when a listing is fixable but heavy.

Josh — App Rescue is the working label for screening, rescue engineering, and post-close ops. Same person, same inbox.

What I do

Offer When it fits
Listing screen You have a URL and want transfer / risk / type (A/B/C) called before you bid
Rescue engineering You bought (or will buy) something real, but the codebase or migration is the blocker
Managed operations The product needs week-to-week care so “passive” does not become downtime
Custom build Marketplace inventory is Type C or gray; you need clean ownership from day one

I do not claim to be a licensed cross-border deal broker. Advisory/brokerage-shaped work stays out of scope until compliance is clear.
