Automotive Connected Fleet: Monolith to Cloud-Native Microservices Migration

Spearheaded the decoupling of a 15-year-old monolithic telematics and diagnostics core into high-throughput, event-driven Spring Boot microservices on Kubernetes.

• Architectural Implementation:
  • Modernized legacy Oracle backend to CockroachDB & TimescaleDB, supporting 2.5M+ active connected vehicles.
  • Implemented Apache Kafka pipelines processing 45,000 telemetry messages/sec with end-to-end P99 latency under 35ms.
  • Architected a zero-downtime Blue/Green deployment strategy across AWS (EKS) and private multi-region OpenShift clusters.
  • Enforced strict ISO 26262 functional safety and UNECE R155 automotive cybersecurity compliance across all telematics ingress nodes.

codeworking.org: Distributed Systems & Java Microservices Curricula

Authored comprehensive architectural deep dives, engineering decision blueprints, and practical computer science curricula translating 15+ years of enterprise Java and microservices production experience for engineering teams worldwide.

• Architectural Implementation:
  • Published battle-tested guides on zero-downtime database migrations (splitting monolithic schemas into microservices data stores).
  • Designed complete reference implementations demonstrating Kafka event-sourcing ledgers and outbox patterns in Java Spring Boot.
  • Formulated resilient service-to-service communication guides comparing gRPC, JSON-RPC, and async messaging under failure scenarios.
  • Mentored mid-to-senior software engineers through structured architectural review rubrics and hands-on production diagnostics.
