What I Do

Hands-on leadership across modernization, architecture, and delivery

  • Platform Modernization

    Incremental migration from legacy stacks to containers, Go, and orchestrated platforms — without risky big-bang rewrites.

  • Backend & Systems Architecture

    Design and evolution of billing, account management, and high-volume backend services with clear operational boundaries.

  • DevOps & Delivery Engineering

    CI/CD pipelines, release automation, artifact management, and deployment patterns teams can run confidently in production.

  • Technical Leadership

    Mentoring, delivery planning, and cross-team coordination that turns architecture into rollout plans teams can execute.

  • Designing service discovery and routing patterns using Consul, Nomad, Traefik, and Akamai
