Service

Backend platforms that scale without drama

Architect and implement services that stay resilient under load, integrate cleanly with your product, and give your team confidence to ship faster.

API foundations

Schema design, versioning strategies, and developer-first documentation to keep integrations effortless.

Operational excellence

Monitoring, alerting, and tracing wired in from day one so issues surface before they impact users.

Security baked in

Authentication flows, permissions, and threat modeling aligned with compliance needs and best practices.

Core capabilities

  • REST and GraphQL services designed for clear contracts
  • Authentication, authorization, and session management
  • Data modeling across relational and document databases
  • Event-driven systems with queues, streams, and workers
  • Infrastructure-as-code and repeatable deployments
  • Automated testing suites and contract validation
  • Continuous delivery pipelines and preview environments
  • Observability dashboards with actionable metrics
