What I'm looking for

Looking for senior remote roles in Technical/Solution Architecture, Cloud Architecture, Backend Engineering, and Distributed Systems. I prefer hands-on roles involving architecture, scalable systems, cloud modernization, microservices, and AI-assisted development, with strong ownership, autonomy, and opportunities to solve challenging technical problems.

I've led backend architecture and cloud modernization for MSCI, Mankara, Cognida.ai, Hitachi Vantara, and Sapient. Most recently, I contribute to Cognida.ai's Zuno Predict V2 forecasting and analytics platform, validating backend, infrastructure, and CI/CD changes across GCP, AWS ECR, GitHub Actions, and Azure DevOps.

I've delivered a 15-microservice Guest Onboarding platform on Rancher Kubernetes and migrated 20 critical MSCI applications to Java 17 and Azure. My work spans Java, Spring Boot, REST APIs, Kafka, Kubernetes, CI/CD, database versioning, IoT systems, and enterprise integrations.
