At Happay, I managed 50+ client accounts for a paperless expense SaaS platform, resolving API issues across onboarding, implementation, and production support. I delivered 50+ HRMS, SAP, and Oracle integrations and reduced troubleshooting time by 50% through structured API testing and updated documentation.
I also designed a secure middleware pipeline for ERP integrations and built a self-healing SFTP ingestion framework. I supported SAML 2.0 Single Sign-On integrations, developed Python-based AWS Lambda functions, and addressed recurring technical issues to strengthen customer retention.
