About this gig

Two systems that will not talk to each other is half my career.


WHAT I INTEGRATE

- Third-party, undocumented, and legacy SOAP APIs

- Webhooks, OAuth2 flows, and rate-limited endpoints

- Payments: Stripe, PayPal, and the reconciliation logic behind them

- Twilio, HubSpot, Shopify, QuickBooks, n8n, Make, Zapier

- Data syncs between systems never designed to talk


RECENT WORK

A Stripe to QuickBooks sync for a logistics company: refunds, partial payments and reconciliation handled automatically. It has reconciled cleanly since launch with no manual fixes.


WHAT YOU GET

- Working integration with retries, idempotency and rate-limit handling

- Logging and monitoring, so you find out before your customers do

- Documented code you own


10 years of software engineering, 210+ projects delivered here at a 5.0 rating. Realistic estimates, because I have been wrong enough times to know how long things take.


Send me the API docs, or tell me there are none. Both are normal.
