Backend Engineering
Build the robust, scalable server-side infrastructure that powers your applications. From high-throughput APIs and microservices to event-driven architectures and database optimization — we engineer backends that handle millions of requests with sub-100ms response times.
Engineer your backendWhat we deliver
Precision-engineered solutions built for your unique challenges and growth ambitions.
API Design & Development
RESTful APIs, GraphQL endpoints, and gRPC services designed for performance and developer experience. OpenAPI documentation, versioning strategies, rate limiting, and comprehensive error handling.
Microservices Architecture
Decompose monolithic systems into independently deployable microservices with clear domain boundaries, event-driven communication, and saga patterns for distributed transaction management.
Database Engineering
Schema design, query optimization, indexing strategies, and migration planning for PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch. Multi-database architectures for polyglot persistence.
Message Queues & Event Streaming
Asynchronous processing with RabbitMQ, Apache Kafka, Redis Streams, and AWS SQS. Event sourcing, CQRS patterns, and real-time data pipelines for high-throughput systems.
Authentication & Authorization
OAuth 2.0, JWT, SAML, and custom auth systems with role-based and attribute-based access control. Multi-tenant authentication, SSO integration, and secure session management.
Caching & Performance Optimization
Multi-layer caching strategies with Redis, CDN, and application-level cache. Database query optimization, connection pooling, and horizontal scaling for peak performance under load.
Our backend engineering process
Domain Modeling & API Design
Map business domains, define aggregate boundaries, and design API contracts. Produce comprehensive API specifications before implementation begins.
Architecture & Database Design
Choose optimal architecture patterns (microservices, modular monolith, serverless), design database schemas, and plan data migration strategies.
Implementation & Testing
Sprint-based development with comprehensive unit tests, integration tests, and contract tests. Every API endpoint is thoroughly tested and documented.
Deployment & Monitoring
Containerized deployments with health checks, auto-scaling, and comprehensive backend monitoring — latency, error rates, throughput, and resource utilization.
