Have questions about hydraulic modeling, SWMM, or need help with migration? I'm always happy to discuss!

This is a fascinating ecosystem because it combines deep domain expertise (50+ years of SWMM) with modern, high-energy "cross-fertilization" from the tech world (Network School).

Here is a diagram representing your specific "Open Source SWMM5 App Ecosystem."

This flow visualizes how inspiration transforms into code and how that code is distributed across your specific channels.

Subtitle: Bridging Deep Hydraulic Modeling with Modern Tech Innovation

• Visual: A split brain or a handshake.

• Left Side (Experience): Icons of water/pipes and a gavel (Committee).

• Text: "Deep Domain Knowledge: EWRI Committee, PDE Modeling, SWMM5/ICM."

• Right Side (Energy): A lightning bolt or vibrant network nodes.

• Text: "Fresh Inspiration: Network School (Malaysia). High-energy coding talent & outside-the-box thinking."

• Visual: An App Window icon.
• Central Rule: "All Apps are Open Source & Public Domain Focused."
• The Fork in the Road:
• Path A: Heavy Duty: Full GitHub Repository.
• Path B: Lightweight: Source code embedded directly in the App's "Doc" tab.

• Visual: A megaphone or signal tower.

• The "Always" Layer:

• ✅ Blog Post (swmm5.org)

• ✅ Tweet (X)

• The "Deep Dive" Layer:

• 📝 LinkedIn Articles (Technical breakdowns)

• 📝 X Articles (Long-form thoughts)

• The "Legacy" Layer:

• 📰 The Newsletter (The final curation of the best work).

It highlights your unique value proposition: You aren't just an engineer, and you aren't just a coder. You are a bridge. You take the inspiration from the youth/tech sector in Malaysia and apply it to the hard engineering of the SWMM5 world, resulting in tools that are shared openly.
