Building Billing Data Gateway v1.0.0: Why I Chose Zero-Copy Architecture
Most cloud billing systems spend more time moving data than processing it.
While building Billing Data Gateway v1.0.0, my goal was to reduce unnecessary memory copies and create a deterministic ingestion pipeline for large cloud billing exports.
Key engineering decisions included:
• POSIX mmap() for zero-copy file access
• Fixed-point 64-bit arithmetic for financial precision
• Bitmask-based validation for efficient record integrity checks
• Streaming JSON and CSV serialization
• High-performance C11 implementation targeting Linux systems
The result was a processing throughput of over 487,000 records per second in benchmark testing.
This project demonstrates how careful systems engineering can improve both performance and maintainability without relying on heavyweight frameworks.
The complete source code, case study, and downloadable product are available on my Contra profile and GitHub.
I'm continuing to build open-source systems software focused on performance, infrastructure, and developer tooling.

ClubTree | All-in-One Membership Management SaaS
Designed and developed ClubTree, a SaaS platform that helps membership organizations manage their websites, members, events, and communications from one centralized system.
ClubTree combines a public-facing website with an administrative dashboard, giving organizations the tools to manage membership applications, member directories, attendance, newsletters, documents, and organizational workflows.
The platform was designed around real-world service club needs, with an emphasis on intuitive navigation, role-based access, and simplifying administrative tasks.
My role: Product strategy, user research, UI/UX design, full-stack development, testing, and launch.
Key features:
- Membership applications and directories
- Event and attendance management
- Website content management
- Newsletters and member communications
- Role-based access and administrative dashboards
- Integrated organizational workflows
Outcome: A functional membership management platform with a live implementation for the Rotary Club of Charlottesville.
Going live with one real club in Charlottesville and building around how they actually run is the right way to do it. Club admin tools usually feel stuck in 2010, so this looks like a big upgrade. How did you land them, through someone in the club?
