Systems & Backend Engineering

Clean, scalable backend systems built with NestJS, FastAPI, PostgreSQL, and Redis. Architecture first, code second.

Systems & Backend Engineering

Concevoir des interfaces que les utilisateurs adorent.

Project Overview

A poorly designed backend is the most expensive technical debt a product can carry. We design data models, API contracts, and system boundaries before writing code.

What We Deliver

  • Clean API Design

    RESTful or GraphQL APIs with consistent contracts, versioning, and OpenAPI documentation.

  • Resilient Data Layer

    Schema design, indexing, migration patterns, and query optimization for PostgreSQL and MongoDB.

  • Background Processing

    BullMQ and Redis-backed job queues for async operations.

How We Build

Domain Modeling

/001

Model your business domain into clean entities, relations, and bounded contexts.

API Contract Design

/002

Define the API surface with OpenAPI specs, shared TypeScript types, and validated DTOs.

Implementation

/003

NestJS modules, FastAPI routers, Prisma schemas, built with layered architecture.

Containerize & Deploy

/004

Docker Compose for dev. Production containers with health checks and proper secrets management.
