Hi there, I’m Tatsuya 👋

I’m a software engineer from Japan currently living and working in Brooklyn, New York.

I’m a senior backend engineer at Quartz, where I lead the design and development of the backend systems that drive the Quartz’s website and apps. This work includes the launch of Quartz membership, Quartz’s first paid subscription service, and the U.S. expansion of NewsPicks, Japan’s leading business news platform, which was later rebranded and integrated into Quartz.

Prior to coming to the news media industry, I was a backend engineer at Gilt, a flash sale site specializing in luxury apparel, where I developed and maintained various user-facing e-commerce functionalities, and Rakuten, Japan’s largest e-commerce platform, where I was building an automated deployment systems for a large-scale, self-service, distributed search platform.

You can also find me on Twitter, Instagram or LinkedIn.

Here is a list of projects I have recently worked on, and here is my latest resume.
