👋 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

• 🌍 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?
