TWJOIN provides professional software takeover and maintenance services. We perform deep diagnostics, performance optimization, and security patching for existing source code to solve technical debt and maintenance issues.

“We don’t just take over your code; we take over your business promise. Professional refactoring restores scalability to legacy systems.”
