The Founder

About Sina Dibay

Sina Dibay

Founder & Software Engineer

I'm Sina Dibay — a software engineer and mentor based in the San Francisco Bay Area. With over 15 years of experience building large-scale distributed systems, cloud architectures, and mobile applications, I founded Dbaydev LLC to help companies design and ship resilient, scalable software.

My expertise spans reactive system design, event-driven architectures, and cloud-native development. I've worked across B2B enterprise platforms and B2C consumer apps — always focused on building systems that perform under pressure.

When I'm not architecting systems, you'll find me creating music. I'm a passionate percussionist specializing in Persian folk music.
