Java Portfolio (Staff/Principal Engineering)

About me

I am Nguyen Khanh (Jeremy) Tran, a Staff-level Java Engineer and Principal Architect with 10+ years of enterprise delivery and 8+ years of technical leadership. I specialize in Java/Spring Boot, distributed systems, and platform modernization with a focus on resiliency, observability, and delivery velocity.

Tech stack

  • Java 21, Spring Boot 3.x, Maven (multi-module)
  • PostgreSQL, Flyway, RabbitMQ
  • Resilience4j, Micrometer, Actuator, Logstash JSON logging
  • JUnit 5, Testcontainers
  • GitHub Actions CI/CD

Leadership highlights

  • Led cross-functional teams building high-throughput, cloud-native platforms.
  • Built platform standards that reduced integration time for new services by weeks.
  • Established production readiness and operational playbooks aligned to SLOs.
  • Recognized for competitive engineering awards in international and national skills competitions.
