Gayangi contributed to API management and gateway solutions across the wso2/apk and wso2/product-apim repositories, focusing on robust configuration, security, and integration features. She engineered unified API definition handling with JSON, YAML, and Swagger support, and enhanced GraphQL and gRPC integration using Go and Protocol Buffers. Her work included implementing Prometheus-based observability, refining JWT and rate-limiting logic, and introducing configuration-driven signature and webhook validation. She improved deployment reliability through Nginx ingress samples and optimized default configurations, while also strengthening documentation and script access controls. Gayangi’s engineering demonstrated depth in backend development, DevOps, and secure, maintainable API infrastructure.

In August 2025, delivered reliable webhook topic validation for API Manager, added integration tests for invalid-topic handling, and refactored test utilities to support custom webhook initialization. These changes improve reliability, prevent misrouted events, and strengthen test coverage, contributing to more robust event-driven integrations and lower incident risk.

July 2025: Delivered a configuration-driven Signature Property Configuration for wso2/product-apim, introducing a new property to store the signature property name to configure how signatures are handled. This enables flexible, safer signature processing without code changes and aligns with future signature algorithm updates. All changes are encapsulated in a single, traceable commit.

April 2025 monthly summary focused on delivering external access capabilities and improving testability for the WSO2 Gateway in the APK repo. Delivered an Nginx Ingress Configuration Sample to enable external access to cluster services and hostname-based routing to the wso2-gateway-service on port 9095, accelerating testing, demos, and environment onboarding. No major bugs fixed this month; primary emphasis on feature delivery, validation, and documentation to raise deployment readiness and operational confidence.

March 2025 monthly summary for wso2/apk: Delivered a critical bug fix to path handling when a backend basepath is not configured, improving routing reliability and reducing potential misrouting in production. Implemented a new constant for endpoint basepath handling, ensured EndpointBasepath is populated in ExternalProcessingEnvoyAttributes, and updated routing logic to append a trailing slash when the basepath is empty to prevent routing errors.

February 2025 monthly summary: This sprint delivered key API governance and observability enhancements across wso2/apk and wso2/product-apim-tooling. Key features delivered include GraphQL API integration and stability improvements in the go-enforcer, API routing/scope/versioning enhancements, API definition handling improvements for gRPC/GraphQL, metrics and observability via Prometheus-ready metrics in gateway enforcer, and a multi-environment JWT requirements flag to support flexible deployments. Major bugs fixed include a custom rate-limiting metadata namespace bug (with organization ID as metadata), scope validation bug, semantic versioning regex matching issue, and API definition go-integration test failures. The combination of these changes improves API reliability, policy enforcement precision, and operational visibility, enabling safer deployments and faster iteration. In addition, operational maintenance included renewing the internal key certificate used by the APIM APK issuer to maintain secure operation. Technologies demonstrated: Go, GraphQL, gRPC, API routing and versioning, semantic versioning, Prometheus metrics, testing, multi-environment deployment strategies, and observability best practices.
