About

Independent software consultant based in Berlin. TypeScript, AWS, and the organizational shapes around them.

I’m Ayhan Sipahi, a software consultant based in Berlin.

I help product teams design and deliver software systems that stay reliable as the product grows. Most of my work is TypeScript and AWS: application code, CDK infrastructure, and how the two fit together.

I write here when something I learned was expensive enough that I’d want someone else to learn it cheaper. Currently noodling on domain-driven TypeScript and CDK pattern libraries.
