Are you facing these issues?
Event Loop freezes during compute-intensive tasks
One \\\\\\\"heavy\\\\\\\" request in a single-threaded runtime blocks servicing of all other clients.
Solution
We move CPU-bound tasks into Worker Threads and microservices, saving the kernel for fast asynchronous I/O.
Spaghetti architecture and lack of uniform code standards
A quick start on pure Express turns into unreadable code after 6 months of development.
Solution
We build a modular architecture on NestJS with strict Dependency Injection, DTO validation and Swagger auto-documentation.
