Intro
Most businesses run on five or six different tools that were never designed to talk to each other — a CRM, a payment provider, an analytics platform, an internal database. API integration is the work of making all of them function as one system instead of five disconnected ones your team manually bridges with spreadsheets.
What this covers:
Connecting internal systems to third-party platforms and data sources through REST APIs, webhooks, or socket connections.
Building integrations that fail gracefully and log clearly, so when something breaks at 2am, your team knows why within minutes, not hours.
Ongoing maintenance as third-party APIs change — a common source of silent, expensive breakage in systems built once and never revisited.
I've built this kind of integration work in financial services, where uptime and data accuracy aren't negotiable.
