I’m a Senior iOS Engineer with 10+ years of experience building high-impact mobile applications for the aerospace, automotive, retail, and financial sectors.

I’ve contributed to mission-critical apps at companies like Airbus, BMW, Payback, and ING, where I designed architectures, delivered end-to-end features, mentored teams, and improved app performance, reliability, and scalability.

I care deeply about creating clean, intuitive and robust mobile experiences that genuinely help people in their day-to-day life.
I enjoy collaborating with product, design and engineering teams to build meaningful software with craftsmanship and purpose.
