But the changin' of winds and the way waters flow
Life is short as the fallin' of snow
And now I'm gonna miss you, I know

Rest in peace my brother.

Hey. I'm David, an experienced software engineer with a strong passion for technical innovation and theoretical research, ranging from software architecture and crypto technology, to programming language design and economics. My areas of expertise include full-stack web development, distributed state management, and pure mathematics. If you must know, I mostly use JavaScript – but on steroids.

    • Takes advantage of WebRTC communication to reduce latency and server infrastructure needed.
    • This was just a fun project and so the sample games are not high-quality.
    • Knows issues: The platform does not work as reliably over hotspots, mobile data, public WiFi and in locations with firewall limitations. It is preferable for everyone to be on the same LAN network and to ensure that direct LAN communication is not blocked. There may be connection issues on older devices.

    • Software tools and services in the crypto space.
