Fase Cuatro - Driving Innovation

Fase Cuatro is a software development and IT consultancy based in Argentina, built around a simple idea: most companies don't need another outsourced coding shop — they need a technical partner who can own a problem end-to-end, from architecture to the servers it runs on.

We're a 17-person team covering full-stack development (NestJS, Next.js, PostgreSQL, Docker), infrastructure and networking, and digital transformation consulting for B2B clients. That combination means we don't just ship features — we design systems that are meant to run in production for years, and we're the ones who get the call when something breaks at 2am.

Our work spans marketplaces with complex transactional logic, internal management platforms with real-time features, gamification and event-tech systems, and IoT/camera integration for field operations. We work in tight iterative cycles, with direct access to senior engineers — not a project manager relaying messages to an offshore queue.

Based in Argentina, we offer US-hours overlap, native-level English communication, and LATAM-competitive rates without the coordination overhead of larger or more distant outsourcing hubs.

If you need a team that treats your product like it's their own, let's talk.
