About this gig

I will integrate your API with two endpoints using Cloudflare Workers, Python, and SQL

Description

Need two systems talking to each other reliably? Ill build a secure API integration that connects your platform to two endpoints and moves data between them automatically.

What I build

  • API connections in JavaScript on Cloudflare Workers: fast, serverless, and low-cost to run
  • Server-side processing in Python for heavier jobs like file handling and payments
  • Records stored in SQL so every transaction and sync is logged and searchable
  • JSON over HTTPS for secure, standard data exchange

Experience with

  • Payment processing
  • File storage and processing (Dropbox)
  • REST APIs, webhooks, API keys, and OAuth

Platforms I can build:

  • Payment and billing portals: customer invoicing, recurring payments, or donation pages with records stored
  • Client document portals: clients upload files that are processed in Python, stored in Dropbox, and logged in your database, which suits services biz, law firms, accountants, or insurance agencies.
  • Membership or subscription sites: sign-ups tied to payments, with auto access control
  • Booking and scheduling systems: appointments with deposits
