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. 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.

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Yes — we handle full migrations from monoliths, outdated Java versions, or legacy enterprise stacks.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.
