API design & development
REST and GraphQL APIs designed for clarity, versioning, and scale.
Backend
Backend systems built to stay out of the way.
We design and build backend systems, APIs, and services that stay reliable, secure, and easy to extend as your product grows.

How we help
A dependable backend is invisible when it's working.
The best backend systems disappear into the background — fast, consistent, and predictable under load. We design for that outcome from the first schema.
Whether it's a monolith that needs structure or a set of services that need clearer boundaries, we build backend architecture your team can reason about and extend confidently.
Reliable, well-tested services
APIs that are easy to consume
Data models built to scale
Clear service boundaries
Capabilities
Built around the work that matters.
Microservices architecture
Break monoliths into services with clear, well-owned boundaries.
Database engineering
Schema design, indexing, and query performance for growing data.
Authentication & authorization
Secure, standards-based identity and access control.
Event-driven systems
Queues and event streams for reliable, decoupled processing.
Performance & scaling
Caching, load testing, and tuning to handle real production traffic.
Our approach
From first question to lasting value.
Model the domain
We map data, workflows, and boundaries before writing a service.
Build the services
APIs and data layers are built incrementally with tests from day one.
Harden for production
Load testing, monitoring, and tuning prepare systems for real traffic.
