PF International LLC — Wyoming, United States
Independent software, built and shipped in house.
We have been building software and advising the people who build it since 2017. Today the company develops and operates two products of its own, and takes on a small number of client engagements alongside them.
Products
we operate
Breathwork for explorers
Pyreva
The breath is a door.
A breathwork app for guided and custom sessions: choose a guide or build your own rounds, breath pace, and hold lengths, with long holds, retention timers, and soundscapes designed for the session. It runs entirely on the device. No account, no ads, nothing to sign up for.
Your personal language assistant
envz
You don't want to learn a language. You want to speak it.
Most language apps teach you to recognize words. Envoz makes you produce them. It is a spoken-practice tutor that remembers you between sessions, works on the pronunciation you actually struggle with, and builds toward real conversations with real people. It teaches Spanish and English, in both directions.
What
we do
Product development
End-to-end work on consumer applications: native iOS and Android, web applications, and the backends behind them. We take products from an idea through store release and keep operating them afterward.
Consulting
Advisory and hands-on engineering for teams that need a specific problem solved rather than a body in a seat. Architecture reviews, difficult integrations, and getting stalled projects moving again.
Platform & infrastructure
Deployment, edge and serverless infrastructure, data storage, and the release tooling that keeps a small team shipping. The same systems that run our own products.
Secure development
Security-focused engineering runs as a separate practice under the PF Systems name, at pfsystems.io.
