01
Build APIs and services with NestJS's structured, modular architecture instead of an unstructured Express app that grows unmanageable.
Preparing experience
Core stack — scalable backend applications
Node.js Development
Node.js, typically with the NestJS framework, is part of WLC's core backend stack. We use it to build APIs, microservices, real-time systems and integration-heavy platforms that need to handle high I/O concurrency reliably.

Why WLC
Built for buyers who need clarity, speed and accountability.
Three principles that shape how we scope, build and deliver every engagement.
02
Handle high-concurrency workloads—real-time notifications, chat, live dashboards—that Node.js's event loop is well suited for.
03
Share TypeScript types between a Node.js backend and a React/Next.js frontend, reducing integration bugs.
04
Design microservices with clear boundaries where a monolith genuinely needs to be split, without over-engineering a small product.
05
Integrate with third-party APIs, message queues and databases through well-tested, documented service layers.
06
Deploy to serverless or containerised environments depending on traffic patterns and cost requirements.
Delivery model
A clean path from idea to launch.

Questions buyers ask
Common questions before starting a project.
Yes—Node.js with NestJS is one of our six core technologies, used for the majority of our backend and API engineering work.
NestJS provides a structured, modular architecture with dependency injection out of the box, which keeps larger codebases organised and testable in ways a minimal Express setup doesn't enforce.
Yes—Node's event-driven, non-blocking I/O model is well suited to real-time features like live dashboards, chat and notifications; CPU-heavy workloads are offloaded to worker processes or separate services.
Either, based on how your clients consume data—REST for simpler CRUD-heavy products, GraphQL when multiple clients need flexible, differently-shaped queries against the same backend.
Yes—we start with a technical audit of architecture, dependencies and test coverage, then propose a plan to stabilise and modernise incrementally, often migrating toward NestJS's structure where it adds value.
