Executive Summary

Led the development of a highly scalable, cloud-native integration platform designed to seamlessly connect internal microservices with third-party SaaS applications. Provided secure, high-throughput API endpoints for B2B enterprise customers.

Cloud-Native API Integration Gateway

The Challenge & Architecture

The client's existing integration layer was highly fragmented, lacking centralized governance, rate limiting, and unified monitoring. I architected a robust API gateway utilizing Ballerina and Choreo to handle complex orchestration, data mapping, and routing. I also enforced strict security policies across the gateway using OAuth 2.0 and JWT validation, ensuring data privacy and compliance across all exposed endpoints.

Execution & Business Impact

Successfully onboarded 50+ enterprise clients within the first quarter of launch. The platform now processes over 10 million API calls daily with sub-50ms latency. Furthermore, centralized observability tools reduced the mean time to resolution (MTTR) for integration failures from days to under 2 hours.
