ABOUT SUMIT SRIVASTAVA
Technical leader specializing in Java-based distributed systems and cloud-native platforms built on Kubernetes.I am a Technical Lead and Senior Java Engineer with 16+ years of experience designing and delivering large-scale distributed systems across banking, telecom, and financial services domains.My core expertise is Java backend engineering and microservices architecture, complemented by deep experience in cloud-native platforms, Kubernetes ecosystems, and DevOps automation. I specialize in building scalable, secure, and highly resilient systems that power enterprise-grade applications.Currently, I work as a Platform Specialist at Publicis Sapient, supporting Lloyds Banking Group, where I lead platform engineering and architecture initiatives for mission-critical banking systems.One of my key contributions has been leading the migration of the INSIS insurance platform from OpenShift to Google Kubernetes Engine (GKE), transforming the platform into a scalable cloud-native architecture supported by standardized Helm deployments, GitOps-driven CI/CD pipelines, and integrated observability solutions. Over the years, I have worked across the entire software lifecycle — from system design and architecture to development, cloud migration, and production operations, enabling organizations to modernize legacy systems and adopt cloud-native engineering practices.Core ExpertiseBackend & Distributed Systems • Java / J2EE • Spring Boot microservices • REST APIs • gRPC and Protocol Buffers • Distributed system designCloud Native & Platform Engineering • Kubernetes (GKE) • Helm • Istio service mesh • Google Cloud Platform (GCP) • Amazon Web Services (AWS) • Microsoft AzureDevOps & Automation • CI/CD architecture • Jenkins and Spinnaker • GitOps deployment models • Production reliability and release governanceIdentity & Security • OAuth2 / OIDC • ForgeRock Identity Platform • Zero Trust architecture • API Gateway integrations (Apigee)Beyond hands-on engineering, I actively mentor teams, review architecture designs, define platform standards, and drive cloud adoption strategies that improve scalability, reliability, and engineering productivity.Areas I’m Passionate About • Cloud-native architecture • Platform engineering • Kubernetes ecosystems • Microservices and distributed systems • Secure identity platforms • DevOps and engineering productivityOpen to discussing Technical Lead, Platform Architect, or Cloud Architecture opportunities focused on cloud-native systems and distributed platforms.
