About Smithin William

Cloud-native backend developer with hands-on experience designing and engineering secure, distributed systems using Java (Spring Boot) and Python, currently working at Equifax Analytics.My core expertise lies in building microservices-based architectures deployed on Google Cloud Platform (GCP), leveraging services like Cloud Run, Pub/Sub, Cloud SQL, Secret Manager, and IAM for scalable, secure application delivery. I actively apply 12-factor principles, domain-driven design, and reactive programming using Spring WebFlux and WebClient to deliver performant, maintainable APIs.I’m deeply involved in DevSecOps practices—implementing CI/CD pipelines with Jenkins and Git, using SonarQube, Fortify on Demand, and Nexus to enforce code quality, vulnerability scanning, and artifact lifecycle management.My experience also includes containerizing applications with Docker for consistent deployments across environments and monitoring operational metrics through GCP Operations Suite (Cloud Logging, Monitoring, Error Reporting).Previously at Geojit Technologies, I worked on core backend modules, focusing on service integration, performance tuning, and technical debt reduction in Spring Boot–based systems.I hold a B.Tech in Computer Science and Engineering from the University of Kerala and am a Google Cloud Certified Associate Cloud Engineer. Passionate about solving complex architectural problems, I specialize in delivering secure, observable, and resilient enterprise-grade software in Agile environments.
