Backend development for APIs, integrations, data pipelines, and reliable product infrastructure.
We build backend systems for products that need reliable APIs, integrations, data flows, and operational stability. This service is deliberately technology-agnostic: the focus is system design, scalability, security, and maintainable delivery rather than a fixed stack. Java and Spring are common but not required. From modular monoliths to distributed event-driven platforms, we build backends meant to support real products under production load.
This service is ideal for companies that:
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.
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.
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.
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.
PDF, XLS, CSV generation · BI integrations · Custom reporting APIs · Data aggregation (OLAP/ClickHouse) · Outcome: reporting that supports decisions and compliance.
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.

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.
