About this gig

Tired of copy-pasting data between apps? Need two platforms to

talk to each other but there's no built-in integration? I'll build

you a custom API connection or automation script that does the

work while you sleep.


I work with REST APIs, GraphQL, webhooks, and custom scripts in

Python, JavaScript, and PHP. Doesn't matter if it's Google Sheets

to CRM, payment gateway to invoicing, Slack to database, or

something more complex I'll make it work.


WHAT I AUTOMATE:

- Data sync between platforms (CRMs, spreadsheets, databases)

- Payment gateway integrations (Stripe, PayPal, etc.)

- Email and Slack notifications triggered by events

- Webhook setup and custom handlers

- Scheduled reports pulled from API data

- Multi-step workflows across multiple apps


WHAT YOU GET:

- Clean, tested, production-ready code

- Step-by-step setup documentation

- Fast delivery and honest communication

- Support after delivery if anything breaks


No fluff, no over-engineering. Just your workflow, automated.


Message me before ordering so we can confirm the scope, APIs

involved, and realistic timeline. If it can't be done, I'll tell

you upfront no wasted time or money.
