Systems that stay fast
under real load.

I'm a Full Stack .NET Developer with 4+ years shipping production software at scale. At Trendyol I worked across 30+ microservices powering e-commerce logistics; at Credit Exchange I'm building a B2B mortgage marketplace for Switzerland. I care about clean architecture, performance and reliability — and I come from a data science background, so the numbers side never scares me.
