About this gig

Spend less time copying data between apps or cleaning the same files. I build small tools that take a repeated task off your hands, with a clear plan for what goes in and what comes out.


Basic: one tool you run manually, one file or one documented API action and one output; validation, a test and a README.

Standard: one workflow linking up to 2 services and 3 API actions, with one trigger, field mapping, error logs, retries and tests.

Premium: one workflow linking up to 3 services and 5 API actions, with one schedule or webhook, duplicate prevention where relevant, logs, a notification and one compatible deployment.


An API is an app connection; each action is an agreed data step. I use Node.js and TypeScript. All packages include source code and setup instructions.


Message me on Fiverr before ordering with your task, sample input/output and API documentation so we can confirm scope. You pay third-party API, hosting and usage fees. Revisions cover adjustments within the agreed workflow.
