GitHub Sponsors Profile

👋 Hi, I'm Tatsuro Shibamura (@shibayan)
Microsoft MVP for Azure (15+ years)
Founder & CEO of Polymind Inc. — Architecting Clarity
I build and maintain open-source tools focused on Azure, serverless, and cloud architecture — with 2,000+ GitHub stars across my OSS projects, used in production environments worldwide.

🚀 What I do

Design and operate Azure-native architectures
Build OSS for App Service / Functions / Container Apps
Maintain critical tooling like Acmebot
Contribute to ecosystem projects (Azure, Terraform, Windows on Arm)

🔧 Key Projects

Acmebot — ⭐ 1.1k
Automated ACME (Let's Encrypt) certificate management for Azure (App Service, Key Vault, Container Apps). Trusted by teams running SSL/TLS at scale on Azure.

Sharprompt — ⭐ 844
Elegant interactive CLI framework for .NET, widely adopted in the .NET ecosystem.

WinQuickLook — ⭐ 387
Bring macOS Quick Look to Windows — lightweight file previewer.

Azure tooling & extensions
Contributing to Azure Serverless, Terraform Provider for Azure, and Windows on Arm ecosystem (vcpkg, OpenCV, WinGet).

🌍 Why it matters
Many of my projects are used in production systems, especially:

SSL/TLS automation on Azure
Serverless workloads (Azure Functions)
Infrastructure & DevOps pipelines

These tools reduce operational cost and complexity —
but they require continuous maintenance, updates, and support.

❤️ Why sponsor?
Sponsoring helps me:

Maintain and support production-critical OSS
Respond faster to issues and feature requests
Keep up with rapid Azure platform changes
Invest time into long-term sustainability

If you're using my tools in your company or product,
your support directly improves the infrastructure you rely on.

🏢 Commercial support (via Polymind)
I also provide:

Enterprise support for Acmebot and Azure tooling
Cloud architecture consulting
Custom development for Azure-based systems

✍️ Writing & Knowledge Sharing

🇯🇵 Blog: https://blog.shibayan.jp
🌍 English posts: https://dev.to/shibayan

I share deep dives into Azure internals, architecture patterns, and real-world lessons.

🎯 Goal
Reaching more sponsors allows me to:

Spend more time on OSS instead of ad-hoc work
Deliver faster updates aligned with Azure changes
Build new tools for the community

☕ Which tier is right for you?
