Backend & automation developer: Cloudflare Workers, Node.js, Make, Airtable

I run a small digital products business with an existing backend that handles quotes, payments and file delivery. The system is live and working, but it needs someone to take over maintenance, finish a number of open items and build a few new automations over the coming months. The stack includes: - Cloudflare Workers (API, webhooks, auth) - A Node.js service on a Linux VPS - Make.com scenarios and Airtable - Payment provider integrations and webhooks - Cloud storage and media CDN APIs - AI (Claude API) inside automations What I'm looking for: - Someone who can read and understand a system they didn't build, and document it clearly - Solid experience with webhooks, API integrations and security basics (signatures, tokens, rate limiting) - Clear, honest communication. If something is outside your experience, I'd rather hear that upfront How we'd start: A small paid task first, then a paid review of the existing system. If that goes well, we continue with ongoing work. Please start your proposal with the word "material" so I know you've read this.
