Microservices Backend Development

We Build Scalable Microservices Backends That Handle Millions of Requests

Your monolith is a bottleneck. Every deploy risks breaking everything. We decompose, design, and build microservices backends on AWS that scale independently, deploy safely, and handle traffic spikes without breaking a sweat.

4 Years Embedded

50 services in one client's production estate

Event-Driven Architecture

Loosely coupled, independently scalable

Production in 30 Days

First service live in one week

30-Day Delivery Guarantee • Fixed-Price • Performance SLA

Common Challenges

When Your Monolith Becomes the Problem

Monoliths work until they don't. Here is what we see every week.

Deploy Fear

Every release is a gamble. One bad deploy takes down everything. Your team ships slower because the blast radius is the entire application.

Can't Scale

Single database, single server. Traffic spikes crash the entire system. You cannot scale the hot path without scaling everything.

Team Bottlenecks

Everyone works on the same codebase. Merge conflicts, slow releases, stepping on each other. Adding engineers makes it worse, not better.

What We Build

Microservices Backends That Actually Scale

Three flavors of scalable microservices backends we build on AWS. Every pattern battle-tested in production.

Event-Driven Microservices

SNS + SQS + EventBridge + Lambda

Loosely coupled services that communicate through events. Independent scaling, independent deploys. One service failing never takes down the rest.

API-First Backends

API Gateway + Lambda/ECS + DynamoDB/Aurora

RESTful and GraphQL APIs with sub-100ms response times. Auto-scaling, rate limiting, caching built in. Handle 10 or 10 million requests without code changes.

Data-Intensive Backends

Kinesis + DynamoDB Streams + ElastiCache + Redshift

Real-time data processing, CQRS pattern, event sourcing for audit trails. Ingest millions of events per hour and query them in milliseconds.

Architecture Patterns

Proven Microservices Patterns We Use

We don't invent new patterns. We apply proven distributed systems patterns that work at scale. Every one of these ships in our backends.

Event Sourcing

Store every state change as an immutable event. Full audit trail, time-travel debugging, and replay capability for rebuilding projections.

CQRS

Separate read and write models. Optimize writes for consistency, reads for speed. Scale each side independently based on actual load.

Saga Pattern

Coordinate distributed transactions across services without two-phase commit. Compensating actions handle failures gracefully.

API Gateway Pattern

Single entry point for all clients. Request routing, composition, protocol translation, rate limiting, and auth in one place.

Circuit Breaker

Prevent cascade failures across services. When a downstream service is unhealthy, fail fast instead of waiting and blocking threads.

Database per Service

Each microservice owns its data. No shared databases, no schema coupling. Services communicate through APIs and events, not joins.
