You need your app to talk to something else. A payment gateway, a CRM, a Payment gate way, an AI model, a mailing service. I've done this across dozens of projects and I know where these integrations break.

I've connected apps to Bachs, Paystack for Payments, Sanity for e-commerce sales automation, Lang-chain for unified AI APIs, and Leaflet for real-time map data. I know how to handle rate limits, webhook reliability, auth flows, and the weird edge cases that vendor docs don't mention.

Audit — I review your existing system and the target API. We map out the data flow, error handling, and edge cases before writing a line of code.

Build — Clean, tested integration code with proper retry logic, caching where it matters, and monitoring so you know when something breaks.

Hand-off — Documented, deployed, and I stick around to make sure it holds up in production.

If your app needs to reliably talk to an external service, that's what I do.
