Hi · Senior Software Engineer · Berlin
Systems that hold up. Apps that feel right.
I’m Siamand. I’ve been building software since 2008, most of it distributed backends for Zalando, Delivery Hero and Glovo. On my own time I make native apps, browser tools and Xi, a programming language. I like hard problems, quiet on-call weeks and getting the small things right.
