About me
Hi, I'm Andrea, a developer with two decades of experience and a growing obsession with software correctness. I'm the creator of beyond-tabs.com, a platform connecting developers with jobs in non-mainstream languages like OCaml, Ada, and Clojure. I also run beyondtesting.dev, where I explore ways to build more reliable software through Design by Contract and related techniques. I recently released RawPair, a terminal-first real-time collaboration tool with zero middleware. I'm also working on Rivar, a minimal language inspired by Eiffel and C, designed from the ground up for native support of contracts.
Featured project: XFrames
XFrames is an open-source library for building GPU-accelerated, cross-platform desktop applications as well as WebGPU-powered UIs in the browser. Designed to make development faster and more accessible, XFrames is ideal for developers seeking high performance and flexibility.

Bringing Design by Contract (DbC) → to PHP.
Invariant PHP is a new PHP extension that introduces class invariants, preconditions, and postconditions—ensuring object integrity and better software correctness.
- Class Invariants (`__invariant()`): ensures object state is valid before and after execution.
- Preconditions (`requires()`): enforce conditions before a method runs (coming soon).
- Postconditions (`ensures()`): validate expected outcomes after execution (coming soon).
