Backend systems engineer in Japan. I build PDF and digital-signature infrastructure in C++ and C# at SkyCom (株式会社スカイコム), and open-source tools for AI agents in my own time.
My day job is SkyPDF: low-level PDF parsing and cryptographic signing in C++ and C# on RHEL, plus the WebAPI, RPM packaging and CI/CD around it. I tracked one API bottleneck through the stack and doubled its production throughput. The My Number Card signing work became a patent, filed jointly with SkyCom in 2025.
Outside work I build automation that has to survive the open internet: anti-bot systems, agents that run unattended for hours, and lately agents that can work a desktop with a real mouse and keyboard. The packages below are public, so you can read the source and install them.
Contact details are on shanewas.com.
| Project | Release | What it does |
|---|---|---|
| agentic-stealth-browser |   |
Browser automation for AI agents that holds up against bot detection: consistent TLS, navigator, WebGL and Canvas fingerprints, human-like input, block detection with recovery, and an MCP server. MIT. |
| edge-agent-bridge |   |
Lets a script or an agent drive the Edge tab you already have open, so logins and VPN sessions survive. 9 ms median round trip, and a 50-action batch runs 7.9× faster than single calls. Local only, no telemetry, no dependencies. MIT. |
| GhostScrape | live | A hosted scraping API built on the stealth engine, with API keys, usage metering, quota billing and rotating proxies. I build and run it end to end. |
| Project | Release | What it does |
|---|---|---|
| doppelhand |  |
Screenshots, mouse and keyboard on Windows for any agent, one JSON object per command. 6 ms actions through a warm local server. MIT. |
| posix-ipc-dotnet |  |
System V shared memory and semaphores for .NET 6 and 8 on Linux, through P/Invoke with no native payload. MIT. |
| engram |  |
Memory for coding agents that syncs between machines, kept as reviewable commits in a private git repo. |
| @shanewas/form-validation |  |
Rule-driven form validation that behaves the same in Node and the browser: cross-field rules, conditions, custom validators. GPL-3.0. |
| ats-resume-analyzer | Scores a CV the way an applicant tracking system would and suggests targeted rewrites. |
Smaller repos: rpm-package (an RPM packaging reference), tunnelfox, oci-defender and StructProbe.
SkyCom Corporation (株式会社スカイコム), software engineer, 2022 to now, Japan
Core developer on SkyPDF, the PDF library and signing infrastructure, in C++ and C# on RHEL. I designed the WebAPI for signing, rendering and conversion, built the RPM packaging and CI/CD pipeline, removed an API bottleneck for a 2× production throughput gain, and filed JP 2025-169170 A on electronic signatures with the My Number Card.
