An unstable backend, faulty synchronizations, and data you can't trust
If your backend runs on old PHP or pure JavaScript without clearly defined data types, a single unexpected value from an external system—like missing data in an ERP price list—can crash the entire client zone. Development slows down, and the team starts putting out fires that should never have reached production.
System crashes
Missing input and data validation causes outages at the worst possible moments.
Slow databases
Poorly designed database queries without indexes slow down the app and frustrate customers.
Unmaintainable code
As features grow, an application without TypeScript becomes unmaintainable and development slows rapidly.
Controlled data integrity
Critical data flows are validated before they reach the database or ordering process.
Asynchronous processing (Queues)
Redis and BullMQ handle demanding background tasks such as PDF generation and price list imports, so the main server is not overloaded.
Modern ORMs (Prisma/Drizzle)
A database layer with types generated directly from the schema, meaning developers guess less and modify code faster.
Scalable server solutions
A fast and reliable backend for demanding applications.A fast and scalable engine for your business
Node.js and TypeScript are standard choices for demanding backends and microservice architecture. They support clean, fast code that remains maintainable after years of development. Thanks to asynchronous processing, Node.js can serve many users concurrently without excessive infrastructure demands.
Why we write backends exclusively in TypeScript
How we design backend architecture
API design
and data rules
We define precise structures for data, API requests, and responses.
Database layer
design
We configure the database, indexes, migration scripts, and ORM models.
Business logic
& integration
Core application logic is connected to ERPs, payments, and email services.
Stress testing
& Dockerization
We test the system's behavior under load and prepare Docker containers for the cloud.
TypeScript backend vs. traditional JavaScript/PHP
When a custom Node.js backend is not the right choice for you
A custom Node.js backend also means regular maintenance, monitoring, and infrastructure responsibility. If you don't need unique logic—such as complex pricing, integration with a legacy ERP, or large-volume data processing—building a backend from scratch may not make economic sense. For standard corporate catalogs or client portals, we'd rather suggest a ready-made platform like Directus.

[email protected]In pure JavaScript, many errors only appear at runtime. TypeScript helps catch them earlier. For example, if a payment gateway expects an amount as a number and text is accidentally sent to the system, the error appears during development, not in production by the customer.
Yes. A custom Node.js backend is ideal when you need to bridge technical debt. We develop a middleware layer that downloads data from the ERP system (like SAP or Pohoda) in the background, converts it into a usable format, and delivers it to the frontend without slowing down the entire application.
The backend is prepared for cloud-native operation in Docker containers. If traffic spikes during a campaign, the infrastructure can add capacity and distribute the load. When the rush ends, performance scales back down so you do not pay for idle servers unnecessarily.
For smaller APIs and microservices, we use fast frameworks like Express.js or Fastify. For larger systems, we choose NestJS, which provides a clear structure, modularity, and better maintainability for long-term development.
