About

Hi, I’m David! I’m an engineering leader and builder currently based in Tokyo 🇯🇵.

I’m an ex-engineering manager from Mercari with over 14 years of experience in the tech industry. I’m experienced in the full stack of application development and have helped businesses ship projects to millions of users. I have a deep passion for building strong, productive engineering teams and reducing friction in the development process.

Today, I focus on indie hacking and building my own business under the name Digital Vibes. I focus on shipping fast and experimenting with new ideas.

You can see what I’m working on here.

What I’m building

I’m currently maintaining and growing a suite of apps focused on productivity, AI, and developer experience:

• ConfigMesh: E2e encrypted sync for your dotfiles and app settings.
• Maskwire: A transparent email proxy for power users.
• Fix My Japanese: AI-powered Japanese grammar correction for iOS and Web.
• Quickshot: A concept photo editor powered by generative AI.

My Process

I’m a big believer in velocity and using AI to handle the grunt work. I recently wrote about my 2026 “Move Fast” Stack if you’re curious about the technical side of how I ship these projects.
