Backend Development
Technology-agnostic backend delivery for complex systems.
We build backend systems designed for high performance, reliability, scalability, and seamless integration with complex business environments. This service is technology-agnostic by intent: we focus on APIs, data flows, integrations, and system reliability. We select the stack based on requirements; Java/Spring is common but not required. For JVM-specific delivery, see Java Development Services. From modular monoliths to distributed event-driven platforms, we design and build backends intended to support real products at scale.
What We Deliver
Microservices & System Architecture
- —Monoliths, microservices, modular architectures
- —DDD, Event-Driven Architecture, CQRS
- —API gateways, service discovery, messaging
- —Stack selection based on requirements (e.g., Java/Kotlin, Node.js, Go)
- —Outcome: architecture that scales cleanly with clear ownership and boundaries.
Database Engineering
- —PostgreSQL 14–16, ClickHouse, Oracle, Redis
- —Data modeling, indexing, partitioning
- —High-throughput analytics, OLAP queries
- —ETL pipelines (Batch + Streaming)
- —Outcome: reliable data models and transparent data flows.
API Development & Integrations
- —REST API design (OpenAPI/Swagger)
- —SOAP services for enterprise systems
- —GraphQL APIs
- —Event streaming: Kafka
- —High-performance RPC with gRPC
- —Third-party system integrations (ERP, CRM, fintech, logistics)
- —So frontends, partners, and legacy systems stay connected without fragile workarounds.
Security & Authorization
- —Spring Security
- —Keycloak, Apereo CAS
- —OAuth2, SSO, MFA, JWT
- —Role-based access control (RBAC)
- —Audit trails & compliance workflows
- —Outcome: secure access control and audit-ready systems.
Reporting & Analytics
- —PDF, XLS, CSV generation
- —BI integrations
- —Custom reporting APIs
- —Data aggregation (OLAP/ClickHouse)
- —Outcome: reporting that supports decisions and compliance.
Performance & Reliability
- —JUnit 5, Testcontainers
- —Load testing and profiling (CPU, memory, SQL)
- —Caching strategies (Redis)
- —Fault-tolerant design patterns, retries, and circuit breakers
- —So systems remain stable under peak load and incidents are diagnosed faster.

FAQ
We select technologies based on system requirements. Java/Spring is a core stack for complex backends, but this page focuses on backend delivery overall. For JVM-specific delivery, see Java Development Services.
Yes. We implement SSO, OAuth2, MFA, RBAC, audit logs, and full enterprise authentication flows.
Yes. We work with REST, SOAP, Kafka, gRPC, and can connect to ERPs, CRMs, payment systems, and custom enterprise software.
Yes — we design and build streaming, event-driven, and horizontally scalable architectures, including systems used in banking, telecom, and SaaS environments.
Yes — we handle full migrations from monoliths, outdated Java versions, or legacy enterprise stacks.
System performance, scalability, security, and availability depend on architecture, infrastructure, workloads, and operational practices. No specific guarantees are provided.
