Hey, I'm Tony 👋

Senior engineer who builds the infrastructure other engineers depend on. CI/CD pipelines, backend services, developer tooling — the work that makes every other engineer on the team faster.


What I work on

  • Multi-agent AI workflows — systems where AI agents collaborate to design, implement, and validate code with real guardrails
  • CI/CD pipelines — GitHub Actions, Jenkins, containerized builds, mutation testing
  • Backend services — Node.js and Java, async patterns, concurrency, data pipelines
  • Developer platforms — local dev environments, observability stacks, runbooks that actually work

Current focus

  • 🌱 Spring Boot 3 microservices on AWS
  • ☁️ AWS Solutions Architect certification
  • ⚙️ Kubernetes and Helm for local developer environments
  • 🦀 Keeping an eye on Go for future projects

Background

Java engineer with a long track record in CI/CD, test automation, and backend services. I've worked across enough messy systems to know that solid pipelines, good test coverage, and readable code are what actually keeps teams moving.

Currently adding cloud-native and AWS depth to a foundation that's been production-tested for years.

I've also led and coached engineering teams, which mostly means I've learned how to spot what's slowing people down and get out of the way of the rest.

Not a front-end developer. Very much a back-end and platform engineer.
