What is Pernix Solutions?
Pernix Solutions is a software engineering company specializing in AI-assisted legacy modernization, spec-driven development, and agentic engineering teams. We work as an embedded extension of mid-market product and engineering teams — typically as a senior pod with a tech lead — rather than as a staff augmentation vendor.
Where we operate
Pernix is 100% based in Costa Rica, headquartered at Terra Campus Corporativo, Tres Ríos, Cartago, Costa Rica. Our engineering staff operates in U.S. business hours, spanning EST through PST. We are an Essential Costa Rica certified company.
Since when
Pernix was founded in 2009 by a group of engineers committed to building a software craftsmanship culture in Latin America. The company has operated continuously since.
