I transform your PHP performance bottlenecks into fast, reliable, and maintainable Rust extensions.
Is your PHP application slow on critical processes?
Do you have a mature PHP codebase, but certain modules are hitting performance ceilings: massive data parsing, intensive calculations, real-time pipelines. Rewriting in Go or Node would mean breaking your existing stack. There's a better option.
What I bring to you
I am a senior backend developer with 15 years of experience in PHP and Rust. I am the maintainer of ext-php-rs, the reference open-source library for writing PHP extensions in Rust. In concrete terms, I bridge the productivity of your PHP ecosystem with the raw performance of Rust — without migration, without disruption.
My expertise covers three areas:
1. PHP Extensions in Rust
Design and development of native PHP extensions in Rust using ext-php-rs. Your PHP teams continue to code normally, but critical processes run at the speed of compiled code. Result: performance gains of x10 to x100 on hot spots, without changing your architecture.
2. Large-Scale PHP / Symfony Backend
Architecture of robust APIs, refactoring of monoliths, performance optimization on high-traffic applications. I have designed systems processing millions of requests for clients like Platform.sh and Lydia Solutions (fintech).
3. Rust Systems for the Web Ecosystem
Development of performant Rust services, CLI tools, and shared libraries. Memory management without a garbage collector, safe concurrency, interoperability with your existing services.
