The Solopreneur Vision

Why ProBackend?

After years of leading teams and architecting enterprise solutions, I founded ProBackend to build products that solve real problems—products that are robust, privacy-focused, and user-centric.

The Mission

Create products that respect user privacy, work offline-first, and leverage intelligent hybrid AI architectures to deliver exceptional experiences without compromising on principles.

"Building products that I would want to use. Engineering solutions that respect the user, not exploit them."
