SaaS API Integration & Webhook Automation
Businesses run on dozens of disconnected SaaS tools. A massive trend on freelance platforms is the demand for developers who can make these tools talk to each other perfectly. I build rock-solid, secure API integrations and webhook listeners that sync your data in real-time. Whether it's wiring up complex Stripe subscription billing, syncing user data to HubSpot/Salesforce, or creating custom Zapier-style internal workflows, I eliminate manual data entry and human error.

Frequently Asked Questions
Yes, I specialize in advanced Stripe integrations, including Stripe Connect for multi-party marketplaces, metered billing usage, and handling complex webhook events for subscription upgrades, downgrades, and prorations.
I build integrations with fault tolerance in mind. If an external API fails, my code catches the error, queues the request in Redis/Database, and implements exponential backoff retry logic so data is never permanently lost.
Exactly. Zapier is great for simple triggers, but it fails when you need complex data transformation, conditional logic, or high-volume syncing without massive monthly fees. I write the custom code to handle what off-the-shelf tools cannot.
