I am a Senior Automation & Integration Engineer with 20+ years of experience designing, implementing, and operating enterprise integration and automation solutions across heterogeneous environments. My background combines traditional enterprise middleware with modern low-code / no-code automation platforms, allowing me to bridge legacy systems with cloud-native and SaaS ecosystems. I have extensive hands-on experience working with IBM Integration Bus, IBM App Connect Enterprise (ACE), IBM MQ, and IBM DataPower, delivering reliable, secure, and scalable integration architectures. In parallel, I have led and executed integrations using Oracle Service Bus (OSB) and Oracle SOA Suite, applying enterprise integration patterns, message mediation, and service orchestration best practices. On the open-source and API management side, I have deep expertise with WSO2 Enterprise Integrator / Micro Integrator and WSO2 API Manager, including gateway configuration, policy enforcement, mediation flows, data services, and API lifecycle management. More recently, I have focused on automation and workflow orchestration using n8n and make, building end-to-end workflows that integrate APIs, SaaS platforms, webhooks, and AI-driven processing. This combination of enterprise-grade middleware and agile automation tools enables me to deliver efficient, maintainable, and business-oriented integration solutions. I am strongly focused on reliability, performance, and observability, with solid experience in troubleshooting, JVM tuning, message flow analysis, and production support across complex integration landscapes.
