RESTful API
design & development
in Pasadena, California

Pasadena's engineering community — Caltech researchers, JPL engineers, professional engineers at Parsons, Tetra Tech, and Jacobs — holds API design to high standards reflecting their professional expectations. Toimi builds APIs for Pasadena companies matching these expectations: clean RESTful design, comprehensive OpenAPI documentation, proper versioning strategies, rate limiting, thoughtful error handling patterns. An amateur API in Pasadena loses credibility with the technical audience this city contains.

Both — the right choice depends on use case. REST APIs work best for resource-oriented designs, HTTP caching benefits, and broad developer familiarity. GraphQL excels when clients need flexible querying and when powering complex frontends. For most Pasadena SaaS platforms, we recommend REST-first approach with GraphQL added for specific use cases providing clear value.

Documentation is the API. We implement OpenAPI/Swagger specifications, interactive documentation portals, comprehensive code samples in multiple languages, runnable examples developers can test immediately. For Pasadena APIs serving research communities, we provide Jupyter notebook examples demonstrating API usage — a documentation pattern researchers particularly value. For APIs targeting engineering audiences, we provide detailed specifications and reference implementations.

We implement modern authentication patterns — OAuth 2.0 with PKCE, API keys with rotation support, JWT tokens, mTLS for high-security enterprise use cases, scoped permission systems. For APIs targeting enterprise or institutional customers, we add SAML 2.0 and OIDC SSO integration. For government contractor-adjacent APIs (relevant given JPL proximity), we implement additional authentication patterns appropriate to federal requirements.

Yes — we architect APIs for traffic patterns typical of successful SaaS and engineering platforms: sudden growth from institutional customer onboarding, sustained high-concurrency use from research workflows, spike patterns from large engineering project deployments. Our API patterns include horizontal autoscaling, Redis caching, CDN-fronted edge caching where appropriate, database connection pooling, read replica routing, circuit breakers.

API versioning is strategic. We implement URL-based or header-based versioning, maintain backward compatibility within versions, publish clear deprecation timelines, provide migration tools for major version changes. For Pasadena API products serving long-term institutional integrations (research platforms, engineering tools), we treat backward compatibility as a core product commitment.

Yes — mature API products ship with official SDKs. We build client libraries in languages Pasadena customers use — typically Python (particularly important for research and scientific computing applications), JavaScript/TypeScript, Java, C++ (relevant for engineering applications), Go, R for statistical computing. Python SDK quality matters particularly given Pasadena's research community Python fluency.

We instrument Pasadena APIs with comprehensive observability — structured logging (often Datadog or Honeycomb), distributed tracing (OpenTelemetry), application performance monitoring, real-time alerting. For API products with enterprise or institutional customers, we build status pages, SLA reporting, customer-visible uptime history.
