Description

You

I bet this is what you're thinking when considering the next step:

💡 You don't have an internal performance testing specialist, but your tech teams are resourceful and capable. They just need a compass and momentum.

✅ We design your strategy together, organize training, and I'll support you along the way.

💡 You want to detect issues earlier. Perhaps your CI/CD could incorporate performance tests. Maybe your developers could offload your specialists...

✅ I frame, I design, I execute, and I drive transitions like Shift-left / Continuous Testing.

💡 You need someone to test, analyze, and improve your software.

✅ Fantastic, I'm hands-on.

Me

I am a Software Performance (Testing) Engineer, whose career can be summarized as 15 years of frowning and saying "it's slow."

I am a specialist who thrives on millisecond-sensitive software and the challenges posed by continuous testing. Whether optimizing an anti-money laundering platform or transforming a startup's testing culture, I bring a balanced mix of technical expertise, empathy, and mutual trust. As a freelancer, I coach teams and advise companies to build fast, scalable, efficient, and resilient software.

When I'm not tracking down response time issues, you'll probably find me hiking in the Alps.
