About this Gig

Get complete API documentation, Postman collections, and data mapping diagrams so your developers integrate faster and stop chasing missing specs.


CBAP® Certified | 5+ Years | SaaS · Fintech · Digital Banking


Poorly documented APIs cause developer delays, failed integrations, and wasted sprints. I eliminate that with structured, developer-ready documentation built to IIBA global standards.


What this Gig delivers:

  • API Reference Docs - endpoints, parameters, payloads & status codes
  • Postman Collections - ready-to-run with test scripts & environment variables
  • Data Mapping & Flow Diagrams - ETL specs & system flows (Lucidchart)
  • OpenAPI / Swagger Specs - YAML/JSON for REST API documentation
  • Auth & Security Docs - OAuth 2.0, API keys & error response patterns
  • Implementation Guides - developer onboarding & edge-case handling


Covers: REST APIs · Webhooks · SaaS integrations · Payment gateways · Microservices


Who this is for:

  • Dev teams inheriting undocumented APIs
  • PMs and BAs bridging business logic to technical specs
  • Startups preparing APIs for partner onboarding


Structured, version-controlled, and handoff-ready.
