About this gig

Two systems that do not talk to each other cost you a person's whole afternoon, every week, forever.


I connect them properly: authentication that does not expire quietly, retries when the other side goes down, and logs that tell you what happened instead of a blank screen.


ALREADY INTEGRATED

Stripe, Authorize.Net, MX Merchant, GoHighLevel, HubSpot, Twilio, ElevenLabs, AWS Cognito, Microsoft and Google SSO, Anthropic, OpenAI, QuickBooks, Airtable, Google Workspace, plus a long list of healthcare and pharmacy APIs.


WHAT YOU GET

A working connection, the source code, and a short walkthrough of how it behaves when something fails. Field mapping you can change yourself.


IF THE DOCS ARE BAD

I have done that before. Undocumented endpoints, odd auth schemes, XML in 2026. Send me what you have.


BEFORE YOU ORDER

Send the API docs and what you want it to do. I will quote you a real number, usually the same day, and tell you if a cheaper package covers it.

20 years in technology. My last company was acquired by a Fortune 50. Most recently I built a HIPAA-compliant healthcare platform that live clinics run their entire business on: React and TypeScript front end, Node and PostgreSQL back end, AWS infrastructure, 20+ integrations across payments, CRM, SMS, voice and SSO. Front end, back end, AI agents, automations, integrations. You get working software early, and you get told straight what is tested and what is not. Message me with what is broken or what you are trying to launch.
