Boris-Andrei P.
API Integration & Invoice Automation | Python & Node.js
I help businesses connect their CRM, accounting, and e-commerce tools and automate document workflows with Python and Node.js. My projects include a Romanian e-Factura XML/UBL pipeline used in an accounting firm’s production workflow, CRM integrations with QuickBooks, Shopify, Twilio and Telnyx, and an LMS administration module. I can help with API integrations and webhooks, invoice data mapping, XML/UBL conversion, troubleshooting existing workflows, and backend tools. I use AI-assisted development, with review and testing against the agreed requirements and expected outputs. Tell me which tools you use and what you need to improve. We can define a focused first milestone before starting.
