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

Frequently Asked Questions
Which technologies are used for backend engineering?
We work with modern backend technologies: Node.js, Python, Java, Go, TypeScript, and others. We choose the best technology based on your requirements, performance needs, and team expertise.
How long does it take to develop a backend system?
Development time depends on complexity and scope. Simple APIs can be ready in 2–4 weeks, while complex microservices architectures with full integration need 6–12 weeks.
Can you work with existing backend systems?
Yes — we can modernize, extend, or integrate existing backend systems into new architectures. We also support migrations from monoliths to microservices.
