Backend Engineering & API Development

High-throughput APIs, event-driven microservices, and distributed systems engineered for reliability, speed, and scale.

Backend engineering is our bread and butter. We build the server-side systems that power modern applications — from simple REST APIs to complex distributed architectures handling millions of requests per day.

Our backend systems are built with observability from day one — structured logging, distributed tracing, health checks, and metrics dashboards so you always know what's happening in production.

We follow battle-tested patterns: CQRS, event sourcing, saga patterns for distributed transactions, circuit breakers for resilience, and rate limiting for protection. No cowboy coding — just clean, tested, documented systems.

What's Included

REST & GraphQL APIs

Well-designed API endpoints with authentication, authorization, validation, pagination, filtering, and comprehensive documentation.

Microservices

Decomposed service architectures with message queues, event buses, service discovery, and independent deployment pipelines.

Real-Time Systems

WebSocket servers, Server-Sent Events, pub/sub systems, and streaming architectures for live data applications.

Background Processing

Job queues, scheduled tasks, batch processing, and async workflows using BullMQ, Celery, or custom queue systems.

Authentication & Authorization

JWT, OAuth 2.0, SAML, API keys, RBAC, ABAC — secure identity and access management for any auth model.

Observability

Structured logging, distributed tracing (OpenTelemetry), metrics collection, alerting, and performance dashboards.
