NestJS Microservice Development Services
We design and build production-grade microservice architectures using NestJS, gRPC, and message queues. From API gateway design to inter-service communication, we deliver backend systems that scale with your business.
The Challenge
Monolithic backends become bottlenecks as products grow. Scaling individual features independently, managing complex business logic across domains, and maintaining system reliability under load require a fundamentally different approach. Many teams struggle with service boundaries, data consistency across services, and the operational complexity of distributed systems. A poorly designed microservice architecture can be worse than a monolith — adding network latency, deployment complexity, and debugging challenges without the benefits of true service isolation.
Our Approach
We follow a domain-driven approach to microservice design. Each service owns its data and business logic, communicating through well-defined contracts. For synchronous operations we use gRPC with Protocol Buffers for type-safe, high-performance inter-service calls. For asynchronous workflows — notifications, order processing, background jobs — we implement message queues with RabbitMQ. Our NestJS monorepo architecture keeps shared code (DTOs, interfaces, utilities) in common libraries while each service deploys independently. We implement the API Gateway pattern to provide a unified REST interface for frontend clients, handling authentication, rate limiting, and request routing internally. In our FoodButik project, we built a 7-microservice backend: 1 API Gateway + 3 gRPC services + 3 RabbitMQ consumers. The system handles ~78 RPC methods and ~80+ REST endpoints with a 10-state order lifecycle, multi-channel notifications (Email/SMS/Push) with exponential backoff retry, and 3 different authentication mechanisms for admin, merchant, and POS device access.
Technologies We Use
Key Benefits
Independent scaling — scale only the services that need it, not the entire system. Fault isolation — a failure in the notification service doesn't bring down order processing. Technology flexibility — each service can use the optimal database and tools for its domain. Team autonomy — multiple developers can work on different services without merge conflicts. Deployment independence — ship updates to individual services without full system downtime. Our implementations include Docker multi-stage builds, Kubernetes-ready health checks, automatic Prisma migrations, and comprehensive monitoring with Sentry integration.
