I will build custom API integrations and automation scripts


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.
