How I brought C-level CSV speed and safety to PHP with FastCSV, a native extension powered by FastCSV-C. Benchmarks, API, and why PHP’s built-in CSV support just isn’t enough.

For years, I had nightmares handling CSV in both Python and PHP—across many real-world projects. Here’s why I built FastCSV-C: a fast, memory-safe CSV library in C, embeddable in any language. Lessons learned about FFI, memory, and performance.

My journey building a PHP extension in Rust and Zig: from wrestling with FFI overhead to discovering when modern languages win (and when they don't). A deep dive into performance, build systems, and the future of PHP.
I've founded two companies and spent 12 years building digital products: Dextra Communication in 2014, then T-Digital in 2021, where I've accompanied startups as both engineer and idea partner.
Today I work on the step before development: helping founders and industry experts decide whether to build, what to build and how, then building alongside them.
I also write about the systems we build — and the systems we use to understand our lives.
Start with a 90-minute Startup Reality Check. You'll leave knowing what to test, what the risks are, and whether to go further.
