Why do you use Next.js and NestJS instead of other frameworks?

Both are mainstream, actively maintained TypeScript frameworks with large ecosystems. Next.js gives fast, search-friendly pages; NestJS gives a structured backend with modules, guards and dependency injection. Using TypeScript on both sides means one language, shared types and one trained team.

Can a modular monolith really scale?

Yes. Our services are stateless, so the same application runs as many instances behind a load balancer, with shared state in PostgreSQL and Redis. Clear module boundaries keep the code organised, and a module can be split out later if there is a proven need — without paying the cost of microservices on day one.

Will we be locked in to your company?

No. Every tool in the stack is open source or an open standard, the code follows written conventions and the API is documented with OpenAPI. Any competent TypeScript team can work on it — and within our own pool, any developer can pick it up.

Do you add Redis and BullMQ to every project?

Only when there is a real need, such as shared sessions, caching with a clear expiry and invalidation plan, or background jobs for emails, reports and imports. We avoid adding infrastructure you would have to pay for and maintain without a reason.

How do you keep the web app, mobile apps and API in sync?

Request and response shapes are defined once as Zod schemas in a shared package. The API publishes an OpenAPI specification generated from code, and the client used by the apps is generated from it — so a breaking change shows up as a type error, not a production bug.

Web & backend stack

A Next.js development company built on one proven stack

Next.js, NestJS, TypeScript and PostgreSQL — the same modern, open-source stack on every web project, so your software is fast, secure and maintainable by any engineer in our pool.

Overview

Why a Next.js development company should standardize

Most software problems that hurt a business — slow releases, fragile code, security gaps, nobody able to take over — come from inconsistency, not from a lack of clever technology. That is why every web and backend project we build uses the same carefully chosen stack and follows the same written engineering standards.

Each choice below is mainstream, actively maintained and backed by a large ecosystem. Together they give you TypeScript end-to-end, server-side rendering for search visibility, a structured backend for complex business rules and a database you can trust with years of data. And because 100+ developers in our pool are trained on exactly this stack, your project never depends on a single person.

The stack

Twelve layers, one deliberate choice each

What we use at every layer of a web application, and the one-line reason we chose it.

Our web and backend technology stack by layer, with the reason for each choice
Layer	Technology	Why we chose it
Monorepo	pnpm workspaces + Turborepo	Web, API and shared code live in one repository, so a change to a data type is updated everywhere in one reviewed step, with cached, fast builds.
Frontend	Next.js (App Router) + TypeScript (strict)	Server rendering gives fast, search-friendly pages, and strict typing catches mistakes before they reach your users.
UI	Tailwind CSS + shadcn/ui	Accessible, consistent components that live in your codebase — no heavyweight UI kit to fight, license or replace later.
Client data	TanStack Query	Caching, retries and background refresh handled the same way on every screen, so the app feels fast and data stays fresh.
Forms	React Hook Form + Zod	Responsive forms that use the same validation rules the server enforces, so users get instant and accurate feedback.
Backend	NestJS + TypeScript (strict)	Modules, dependency injection and guards keep large codebases organised and make security checks hard to forget.
Database	PostgreSQL + Prisma	A proven relational database with type-safe, parameterized queries and versioned migrations for every schema change.
Cache / jobs	Redis + BullMQ	Added only when there is a real need: shared sessions, caching with a clear expiry, and background jobs for emails, reports and imports.
File storage	S3-compatible storage	Durable storage with pre-signed uploads, type and size checks, and user files never served from the application's own domain.
API	REST, versioned /v1, OpenAPI generated from code	Predictable, documented endpoints and a generated client, so web and mobile apps never drift out of step with the API.
Testing	Vitest, Supertest, Playwright	Unit, API and end-to-end tests for critical journeys run automatically in CI on every change.
Logging / errors	pino, Sentry	Structured logs with a request ID on every line and real-time error alerts, so problems are found and fixed quickly.

Architecture

Simple to run today, ready to scale tomorrow

Every application follows the same architecture, so any developer can open any project and know where things live.

Modular monolith
One NestJS application split into clear feature modules. You get simple deployment and debugging today, and clean seams to split out a module later if a real need appears — no premature microservices.
Stateless services
No in-memory sessions or state. Anything shared lives in PostgreSQL or Redis, so every service can run as multiple instances and scale horizontally from day one.
One source of truth for types
Request and response schemas are Zod schemas in a shared package. The API generates its OpenAPI specification from code and the frontend uses a generated client, so types never disagree.
Layered dependencies
Controllers → services → repositories/Prisma. Controllers never touch the database and business logic never sits in the UI, which keeps code testable and easy for any developer to navigate.

Security by default

Standards that are enforced, not optional

Server-side Zod validation on every input, RBAC guards with record-level checks on every endpoint, argon2 password hashing, secure cookie sessions, rate limiting, Helmet and a CORS allowlist, and secrets only from validated environment variables.
