About OST

A studio of one —
with the output of many.

OST is run by Orçun Sami Tandoğan, a software engineer currently living and working out of a van in New Zealand. No account managers. No middlemen. You talk directly to the person building your product.

Over 20 products shipped remotely — education platforms, AI apps, real estate tools, data pipelines, and more. All solo. All production-grade.
