Backend Developer - Integrations & Third-party APIs

Buenos Aires, Argentina·4+ years·Spanish / English

Bio

I connect systems that weren't designed to talk to each other. 4 years building integrations with payment providers, CRMs, marketing tools, and shipping APIs. I handle webhooks, rate limits, and retry logic. Self-taught developer who started in customer success and got tired of manual data entry. My integrations are robust, well-logged, and handle failures gracefully. Very detail-oriented with error handling.
