Your tools don't talk to each other. Orders come in through your shop but someone still copies them into the CRM manually. The warehouse system is its own island. Reports are assembled by hand every Monday morning.
I build the connective tissue between your systems โ reliable, well-tested, and observable. When something breaks (and something always does), you know about it before your customers do.
I've integrated with Stripe, Zoho CRM, Airtable, custom ERPs, logistics APIs, government VAT services, and dozens of other platforms. I know how to read poor documentation, deal with rate limits, and build retry logic that actually works.
What's included
- REST and GraphQL API design and implementation
- Stripe, Zoho CRM, Airtable, ERP integrations
- Webhooks, event queues, and real-time data sync
- OAuth 2.0 and API key authentication flows
- Rate limiting, retry logic, and error alerting
- API documentation
How I approach this
01
Audit the landscape
Understand every system involved: APIs, auth methods, data formats, rate limits, failure modes.
02
Design the contract
Define exactly what data flows where, in what format, on what triggers. Agree before building.
03
Build with resilience
Every integration is built to handle failures gracefully: retries, dead-letter queues, alerting.
04
Monitor in production
Integrations are only as good as their observability. Logging and alerting built in from the start.
