Project details

Turn an incomplete OpenAPI or Swagger specification, Postman collection, or endpoint list into documentation developers can actually use. You will receive a structured guide with setup, the agreed endpoint coverage, request and response examples based on your source material, common errors, and a concise handoff. Every package includes proofreading and scope confirmation before drafting. Delivery can be Markdown, repository-ready text, or another agreed format. English and Spanish documentation are supported. Where you provide a safe test environment, examples can be exercised and inconsistencies noted. Standard and Advanced packages can include additional research and references; Advanced also includes a compact style guide for consistent future updates. Please share only the source material needed for the project and remove private production data.

About Javier

Javier N.Status: Offline
API & Automation Developer | Python, TypeScript, n8n, Pine Script
Valencia, Spain - 10:33 am local time
I deliver bounded technical and operations work with clear scope, reproducible checks, and concise handoff notes.

Services I can deliver:
• Python and Node/TypeScript API debugging
• n8n workflows, webhooks, data mapping, retries, deduplication, and error paths
• Pine Script logic, alerts, exits, and repainting checks
• CSV/CRM cleanup with validation and QA reports
• English-to-Spanish technical translation and proofreading
• API/product documentation, market research, and functional QA

For a first engagement, send the source files or failing behavior, a representative sample, expected output, and any terminology or style requirements. I confirm the definition of done, delivery time, and fixed price before starting. I prefer redacted fixtures and test credentials; production secrets are unnecessary for most jobs. Every delivery includes the agreed artifact, verification evidence, and limitations. I do not promise trading profits, guaranteed uptime, or results outside the agreed tests.

Steps for completing your project

After purchasing the project, send requirements so Javier can start the project.

Delivery time starts when Javier receives requirements from you.

Javier works on your project following the steps below.

Revisions may occur after the delivery date.

Review source material and confirm scope

I validate the supplied endpoints, audience, examples, terminology, and output format, then confirm the exact coverage before drafting.

Draft and verify the documentation

I write the guide and examples, verify the documented flows against the supplied specification, and check terminology, links, structure, and edge cases.

Review the work, release payment, and leave feedback to Javier.
