About this gig

I connect the software your business already runs on, so data stops being copied by hand.

I build API integrations and webhook pipelines between CRMs, accounting tools, ERPs, payment providers and internal databases: HubSpot, Stripe, Pennylane, Sellsy, Odoo, Airtable, Notion, Google Sheets, and any documented REST or GraphQL API.

WHAT YOU GET

- A working integration, deployed and running

- Field mapping agreed before a line of code is written

- Retry and error handling, so a failed sync never disappears silently

- Readable logs and a short handover document

HOW I WORK

1. Free 15-minute call to confirm systems, sync direction and volume

2. Written scope: endpoints, field mapping, failure behaviour

3. Build, then test against your data in a sandbox

4. Deploy, monitor the first days, hand over docs

WHY ME

Data scientist, MSc Financial Engineering (UCLA Anderson). I have connected CRMs to accounting software and HR systems to CRMs, and built the reporting on top. European timezone, French and English, EU data hosting.

Message me with the two systems and what should happen when a record changes. I will tell you which package fits before you order.
