API and Backend Engineering
We design and build robust backend architectures capable of handling heavy concurrent traffic. With strict schema contracts, connection pooling, and token-bucket rate limiting, your services remain responsive under load.
Commercial & Technical Benefits
Contract-first OpenAPI specifications ensure frontends and backends never drift
Sub-20ms database queries through optimized indexes and Redis caching
Cryptographically signed webhooks with guaranteed delivery and retry queues
Clean domain-driven separation for ease of future team expansion
What We Build
- High-throughput REST and GraphQL backend services
- Relational and document database architecture and indexing
- Distributed background job workers and message queues
- Third-party enterprise API integrations (payment, CRM, ERP)
What You Receive
- Backend microservices / monolith codebase in Python or TypeScript
- Interactive Swagger / OpenAPI 3.1 documentation
- Redis caching and distributed rate-limiting engine
- Comprehensive integration test suite and database migration scripts
