APIs built to a contract,
not to a guess.
Custom REST APIs for SaaS products, mobile apps, and third-party integrations — designed against an OpenAPI spec first, then built, documented, and hardened for production traffic.

Every build ships as a complete, integratable API
Not just working endpoints — a documented, secured, versioned contract other developers can build against without asking questions.
OpenAPI specification
A versioned 3.1 spec that doubles as the source of truth and generates interactive docs automatically.
Auth & access control
OAuth2 or JWT-based authentication, scoped API keys, and role-based permissions on every route.
Rate limiting & throttling
Per-key and per-route limits with standard headers, so abusive traffic can't take the service down.
Automated test coverage
Contract tests validate every endpoint against the spec so a broken response never reaches a client.
Webhooks & async jobs
Outbound event delivery and queue-backed background processing for anything too slow to run inline.
Monitoring & alerting
Error tracking, uptime checks, and latency dashboards wired up before the API goes live, not after.
Built on frameworks your team already trusts
The API adapts to your existing backend rather than forcing a new one.
Four stages, in this order, every time
The contract gets designed before a single endpoint gets written — it's the step most rebuilds skip, and the reason APIs drift out of sync with their docs.
Design the contract
Map resources, routes, and payloads into an OpenAPI spec. Reviewed and signed off before any code is written.
Build & document
Endpoints, validation, and auth get built against the spec, with docs generated from the same source.
Test & harden
Contract tests, load checks on hot routes, and a security pass on auth, rate limits, and input handling.
Deploy & monitor
Shipped with error tracking and uptime monitoring in place, plus a versioning plan for what comes next.
Built for teams that need the API to just work
SaaS products needing a public API
A stable, versioned surface customers and partners can build integrations against.
Mobile apps needing a backend
A dedicated API layer for iOS, Android, or Flutter clients, separate from any web app.
Connecting existing systems
A middle layer that lets a CRM, payment processor, and internal tools talk to each other reliably.
Replacing a fragile legacy API
An audit-first path off an undocumented API that's become too risky to change.
Three ways to work together
Exact pricing depends on endpoint count, auth complexity, and integrations — scoped after a short discovery call.
Project-based build
A defined set of endpoints, delivered against a fixed spec and timeline. Best when the requirements are already clear.
- OpenAPI spec + build + docs
- Fixed price, milestone-based
Hourly development
For evolving scope — new endpoints, integrations, or refactors added as priorities shift during the build.
- Weekly progress + working demos
- Scope adjusts as you learn
Maintenance & support
Monthly retainer covering monitoring response, new endpoints, and version upgrades once the API is live.
- Priority bug response
- Monthly capacity reserved
Common questions
An API contract (OpenAPI 3.1 spec), the built endpoints, authentication and authorization, input validation, rate limiting, consistent error handling, automated tests, and hosted documentation. Deployment and monitoring setup are included for production launches.
Most builds use PHP with Laravel or Node.js with Express/Nest, matched to your existing stack. Both support OpenAPI generation, queue-backed jobs, and standard OAuth2/JWT auth patterns.
Yes. An audit covers versioning, response consistency, N+1 query patterns, auth gaps, and missing rate limits, followed by a prioritized fix list or incremental refactor instead of a rewrite.
OAuth2 or signed JWTs, scoped API keys, per-route rate limiting, schema validation, enforced HTTPS, and audit logging as standard. HIPAA/SOC2-aligned builds add stricter access controls and encryption at rest.
A focused API covering 10–20 endpoints with auth and documentation typically takes 2–4 weeks. Larger or multi-service builds run longer and are scoped after the contract-design pass.
Yes — every build ships with an OpenAPI/Swagger spec and hosted interactive documentation, so frontend, mobile, and third-party developers can integrate without back-and-forth.

Have an API that needs building — or fixing?
Send over what you're integrating with and what it needs to do. A scoped plan, with endpoints and timeline, follows from there.
