I will build reliable ghl, n8n, CRM and API automation systems
API Automation and QA Developer
I am a software developer experienced in web development and quality assurance. I build reliable REST APIs, Python automation, Laravel and Vue features, data-processing workflows, and automated tests....
About this Gig
I design and build reliable business automation that connects forms, GoHighLevel, n8n, CRMs, APIs, databases, email, and team notifications.
This is more than a happy-path workflow. I account for validation, duplicate events, API failures, retries, audit logs, and safe reprocessing.
Typical deliverables:
workflow and data-flow design
n8n or custom Python implementation
CRM, webhook, email, Slack, database, and SaaS API integration
idempotency, retry, rate-limit, and error-handling rules
sandbox validation and automated tests
deployment guidance and written handoff
My public reference implementation connects n8n and GoHighLevel with lead identity, retry and replay behavior, AI-output validation, operational controls, and 228 automated tests.
Please provide the current workflow, desired outcome, systems involved, API documentation, sample payloads, sandbox access, and acceptance criteria. I work asynchronously and do not require video meetings.
FAQ
Do I need to provide production credentials?
No. Please use a test account, sandbox, or temporary least-privilege credential. Never send production passwords or unrestricted secrets in chat.
Which systems can you connect?
I can work with GoHighLevel, n8n, REST APIs, webhooks, forms, spreadsheets, email, Slack, and similar SaaS tools when suitable API or test access is available.
How do you prevent duplicate records and silent failures?
Standard and Premium can include idempotency, validation, retries, error alerts, structured logs, and automated tests. Exact controls depend on the connected systems.
Can you work asynchronously without meetings?
Yes. Written requirements, sample data, acceptance criteria, and test access are usually sufficient. I provide written progress updates and a documented handoff.
