Integrations
Build integrations with your existing product
I build reliable integrations between your product and third-party systems. OAuth flows, webhook handling, data sync, error handling, and monitoring — all the details that make integrations actually work in production.
This is for products that need to connect to Stripe, HubSpot, Salesforce, accounting systems, or any other API. Built to handle the reality of production: rate limits, retries, idempotency, and webhooks that arrive out of order.
Integrations I've built
Stripe, Xero, QuickBooks, HubSpot, Zendesk, Salesforce, Google Workspace, Office 365, GitHub, Jira, Linear, Apple/Google Pay, App Store/Google Play, POS systems, and obscure vendor APIs.
What you get
- OAuth or API key authentication that doesn't break
- Webhook handling that works when events arrive out of order
- Retry logic for transient failures
- Idempotency to prevent duplicate operations
- Data mapping and transformation
- Audit trails and monitoring
- Documentation for your team
Good fit if you need
- Integrations that won't silently fail
- To connect your product to third-party systems
- Proper error handling and monitoring
- Someone who's built these integrations before
Approach
- Time & materials for exploratory integration work
- Fixed-price for well-defined integrations
- Typical timeline: 2–6 weeks per integration
