Backend Engineering

Enterprise-grade backend systems, scalable APIs, and microservices architecture

We design and build backend systems that are secure, scalable, high-performance, and ready for long-term growth.

From enterprise integrations to real-time APIs and microservices — we engineer systems that power critical business operations without downtime. Our backend architecture ensures that your product remains fast, reliable, and stable under load, regardless of complexity.

Problems Backend Engineering Solves

  • slow, unstable backend logic
  • legacy monoliths that can't scale
  • performance bottlenecks under increasing traffic
  • inconsistent APIs or undocumented logic
  • difficulties integrating with ERP/CRM/internal systems
  • manual processes that should be automated
  • security vulnerabilities and poor access control
  • lack of monitoring and traceability

Automation eliminates these risks completely.

What the Solution Includes

Backend Architecture Design

Scalable, modular systems tailored to business logic and technical constraints.

  • service architecture (monolith → modular → microservices)
  • domain-driven design (DDD)
  • real-time or event-driven patterns
  • database schema design
  • performance and capacity planning
  • reliability, consistency, and fault-tolerance

API Development & Integrations

Robust APIs for internal systems, apps, dashboards, and external partners.

  • REST / GraphQL / gRPC / Webhooks
  • secure authentication (OAuth2, JWT, SSO)
  • ERP / CRM / third-party integrations
  • synchronous & asynchronous communication
  • API versioning and governance
  • documentation (OpenAPI / Swagger)

High-Performance Backend Systems

Backends optimized for reliability and speed.

  • caching layers (Redis, Memcached)
  • queue systems (Kafka, RabbitMQ, SQS)
  • load balancing
  • concurrency and throughput optimization
  • rate limiting & API protection
  • horizontal scaling strategies

Microservices & Distributed Systems

Modern, decoupled backends that scale with your product.

  • microservices structure and communication
  • event-driven and message-based architecture
  • service discovery and orchestration
  • resilient services with retries/fallbacks
  • observability and tracing

Security & Compliance

Enterprise-grade infrastructure and data protection.

  • IAM & RBAC
  • encryption at rest and in transit
  • secrets management
  • audit logs and compliance alignment
  • secure deployment pipelines

Maintenance, Monitoring & Continuous Improvement

Backend systems that improve over time.

  • SLO/SLA/SLA tracking
  • error/incident monitoring
  • logs, metrics, traces
  • root-cause analysis
  • maintenance routines and performance tuning

How It Works

  1. 1Assess Your Current Backend — We analyze architecture, performance, database structure, integrations, and bottlenecks.
  2. 2Design Backend Architecture — We create a scalable blueprint for APIs, data flow, logic, and microservices.
  3. 3Implement & Refactor — We build backend modules, integrate external systems, and optimize performance.
  4. 4Deploy & Operate — Seamless CI/CD integration, observability setup, and production rollout.
  5. 5Improve & Scale — Continuous improvements based on load, usage, and business growth.

A strong backend foundation enables reliable growth, stable releases, and predictable operations.
