API design and development
REST and GraphQL APIs with clear contracts, versioning, and auth patterns.
APIs that other teams can trust
Design, build, and harden APIs for product teams, partners, and internal systems, with documentation and observability included.
Talk about your API workWhat we build for API programs
Contract-first APIs, integrations, and the operational layer that keeps them reliable.
System integrations
Connect ERP, payments, CRM, and partner systems without brittle glue code.
API modernization
Replace fragile endpoints with documented, testable services your teams can extend.
Platform and gateway work
Rate limits, keys, monitoring, and the controls ops needs in production.
Capabilities that keep APIs healthy
From contract design to security and the tooling developers need day to day.
- RESTful and API-first architecture
- Secure authentication and authorization
- API design, documentation, and versioning
- High-performance and scalable API development
- Ongoing maintenance, monitoring, and support
- Performance optimization
Why teams pick PySquad for APIs
APIs are products. We treat contracts, reliability, and docs as first-class work.

API development FAQs questions
Questions teams ask before API design, build, or integration work.
API strategy, REST and event-driven design, implementation, versioning, documentation, security, rate limiting, and integrations between products, ERP, payment, and partner systems.
Python (Django, FastAPI), Node where it fits, PostgreSQL and Redis, OpenAPI specs, and cloud-native deployment with logging, metrics, and tracing for production support.
Yes. We define auth models (OAuth2, API keys, JWT), pagination, idempotency, webhooks, and sandbox environments so partners and mobile clients integrate predictably.
We map entities and events, choose sync vs async patterns, add retries and dead-letter handling, and document contracts so operations teams can monitor and support integrations long term.
Yes. OpenAPI/Swagger, examples, changelog discipline, and optional SDK guidance so internal and external developers can adopt APIs without constant engineering support.
Share your systems diagram and integration goals. We run a short discovery, propose architecture and milestones, and start with the highest-risk integration or core domain API first.
