Founder of DigitalPlat Foundation and EdgeAlphix LLC
Production internet infrastructure, operating at global scale.
Edward Hsing, also known as Yujie Xing, builds and operates production internet infrastructure used by more than 400,000 users across 200+ countries and regions. The work spans DNS, BGP, operating systems, containers, and network infrastructure, and includes one of the most starred infrastructure projects on GitHub with more than 150,000 stars.
About
Systems built for real-world production constraints.
The work sits between low-level systems engineering and public internet operations: kernels, service managers, DNS, container systems, routing, and the network software required to keep real services running under load.
Started early, with real systems from the beginning.
Infrastructure work started at 15, with a focus on systems that handle real users rather than experimental prototypes. DigitalPlat Foundation was later established to build internet infrastructure for developers, students, and open communities, and is fiscally sponsored as a 501(c)(3) by The Hack Foundation. The same expectation remained throughout: the systems needed to carry live traffic and stay reliable in production.
That approach continues through EdgeAlphix LLC in the U.S., with end-to-end ownership across system design, low-level implementation, deployment, and day-to-day operations.
Companies
Infrastructure in active operation.
The largest deployed system today is DigitalPlat FreeDomain, alongside standards-oriented infrastructure at OpenSource.ngo and the network build-out underway at EdgeAlphix.
DigitalPlat FreeDomain
FreeDomain is a production DNS and provisioning platform operated through DigitalPlat, built to issue and manage free domains and subdomains at global scale. It serves real users across more than 200 countries and regions and has been designed, implemented, deployed, and operated end to end by a single developer with a strong emphasis on reliability and operational control.
- 500,000+ domains registered and actively used across more than 200 countries and regions.
- 154,000+ GitHub stars, making it one of the most starred infrastructure projects on GitHub.
- Deployed across 10+ regions and used in 200+ countries and regions.
- Supported by Cloudflare, GitHub, 1Password, Twilio, Vercel, and Hack Club programs.
OpenSource.ngo
OpenSource.ngo is a production-oriented data infrastructure project for publishing open-source license information in a cleaner, machine-readable form, with full text and provenance across 167 SPDX licenses.
EdgeAlphix Infrastructure
EdgeAlphix is the operating base for IP infrastructure, BGP peering, and the network systems behind a broader long-term build-out. The work is focused on deployable network infrastructure rather than conceptual design.
- Allocated IP address space with active ASN integration work.
- Ongoing BGP peer deployment and groundwork for future Anycast capabilities.
- The network is being built for global use, not a single region.
Projects
Technical projects.
The underlying systems work includes kernels, service managers, Linux environments, and tooling built with the same expectations as production infrastructure: technical depth, operational clarity, and practical use.
EdgeOS
EdgeOS is a Linux-compatible operating system focused on syscall and userspace behavior, built so standard Linux software can run without modification on a separately implemented system.
- Multi-user UNIX environment with ext4, process isolation, and a Linux-compatible syscall ABI.
- Runs BusyBox, OpenSSL, Dropbear SSH, and CPython 3.12 unmodified.
- Includes IPv4/IPv6 networking, framebuffer support, USB 3.0 xHCI, and persistent storage.
FlyOS
FlyOS is a persistent Linux environment for Android that turns mobile hardware into usable Linux workstations without requiring kernel changes, with an emphasis on stable long-running environments rather than temporary sessions.
- Runs full Linux environments via chroot with multi-container support.
- Includes terminal, noVNC desktop access, service management, and remote access paths.
- Supports WINE, ADB integration, VPN access, USB networking, and Cloudflare tunneling.
initd
initd is a lightweight, systemd-compatible init system built to run unmodified service files in constrained, containerized, and stripped-down Linux environments where full systemd is often a poor fit.
- Drop-in compatible service model and familiar systemctl workflow.
- Works as PID 1 or as a standalone manager with full process supervision.
- Built for containers, embedded environments, and stripped-down Linux systems.
GPTWiki
GPTWiki is a structured content pipeline for turning crawled sources into publishable wiki-style knowledge, with automated workflows and repeatable data handling for large documentation sets.
- Configurable ingestion from Reddit, Stack Overflow, and other sources.
- Structured content generation designed for knowledge extraction at scale.
- Integrated with Pywikibot-based publishing workflows.
