"I’ve spent 15 years in Java and currently manage a library of 2,000+ verified business systems (ERP, CRM, WMS).
Lately, the hype is all about Next.js, Supabase, and PostgreSQL. I love them for speed, but let’s be honest: Building a 'One-Click Run' SaaS is easy. Building a tax-compliant inventory system with complex state machines is hard.
I’ve seen developers spend 3 hours failing to configure environments for these 'old' Java projects. That’s why I’m building the L3 Engine—to make these 2,000+ battle-tested systems run in 1-click.
The Real Question: If you could get the complete backend logic (API, Database schema, Business rules) of a professional ERP for free and run it in a 1-click sandbox—would you still care that it’s 'Old Java' instead of 'Next.js'?
Or is the modern stack more important than the 500+ hours of business logic inside the legacy code?
Let’s debate. (I’m pulling real logs from my 540k-user platform to see if the demand is still there!)"
