Accepting new projects

We engineer software that actually ships.

Guavex Pro designs, builds and scales web platforms, mobile apps, payment systems and cloud infrastructure — from first commit to production traffic.

We hold our work to one standard: it runs in production, reliably, long after launch. The systems we build process payments, manage networks and support the daily operations of businesses that depend on them.

What we build

If it runs on a server, a phone
or a chip — we build it.

Web Platforms

Full-stack products from dashboard to database. SaaS, marketplaces, internal tools — built to scale past your first ten thousand users.

Mobile Apps

Native-quality iOS and Android apps from a single codebase. Offline-first, push-ready, and smooth at 60fps.

Payments & Fintech

Card rails, mobile money, reconciliation, billing engines. We've moved real money through systems we built — reliably.

Cloud & DevOps

Infrastructure as code, CI/CD pipelines, observability. Deploys that take minutes, not meetings.

AI Integration

LLM-powered features, retrieval pipelines and automation that solve real workflows — not demos that die in staging.

Systems & Networking

Subscriber management, router automation, real-time engines. The unglamorous backbone software most agencies can't touch.

Selected work

Proof, not promises.

How we work

From idea to production
in four moves.

  1. 01

    Discover

    We dig into the problem, the users and the constraints before writing a line of code. You get a scoped plan with honest estimates.

  2. 02

    Design

    Architecture and interface together. We prototype the risky parts first so surprises happen on week two, not week twenty.

  3. 03

    Build

    Short cycles, working software every week, and a staging link you can click from day one. No black-box development.

  4. 04

    Ship & Scale

    CI/CD, monitoring and on-call support. We stay after launch — because production is where software actually starts.

Tooling

A stack chosen for longevity.

Boring where it should be boring, cutting-edge where it pays off. Every choice is something your next engineering hire will thank us for.

Have something hard
to build? Good.
