Hi, I'm Sean Hayes

Software Engineer based in Waxhaw, NC, building secure, reliable systems in mission-critical environments. I work primarily with Java and Spring, with a strong interest in cloud-native architectures and DevOps practices.


What I'm focused on

  • Designing and shipping scalable Java/Spring services in classified and high-security environments
  • Streamlining delivery with GitLab CI/CD pipelines and automated quality gates
  • Hardening systems for reliability, observability, and security from day one

How I work

  • Engineering mindset: I care about clean, testable code and reproducible builds
  • Ops-aware: I think about deployment, monitoring, and failure modes while designing features
  • Collaborative: I enjoy pairing with teammates, reviewing code, and iterating quickly on feedback

Currently exploring

  • Kubernetes and container orchestration for scalable, resilient services
  • Grafana and related tooling to improve visibility into complex, distributed systems
  • Evolving CI/CD pipelines to support faster feedback and safer releases

Topics I enjoy discussing

  • Test-driven development (TDD) and CI/CD best practices (Jenkins, GitLab, etc.)
  • Building and operating microservices with Java & Spring Boot
  • Architecting secure systems for sensitive and classified environments
  • Making the jump from networking/infrastructure into software engineering

A bit of background

Before software engineering, I served as an Intelligence Analyst in the U.S. Navy.
That experience trained me to:

  • Break down ambiguous, high-stakes problems into actionable pieces
  • Analyze data under pressure and communicate clearly to decision-makers
  • Bring an operational perspective to how systems are designed, deployed, and used

That mix of operational experience and engineering helps me design systems that not only work in theory, but hold up in real-world conditions.

If youโ€™re working on something in the Java/Spring, cloud-native, or DevOps space and think I could help, Iโ€™m always open to a conversation.
