Current focus: maintain and improve the shipped Node.js/React customer portal on AWS (Terraform-managed infra, Postgres, GitLab for source control/CI‑CD). Greenfield charter: plan and deliver GoLang backends with React/TypeScript frontends for a modular TMS and other new projects on the same AWS/Terraform/Postgres foundation, ensuring these systems integrate with each other and the portal.

Plan and design module/service boundaries, contracts, and data ownership for microservices; choose sync/async integration patterns so new systems integrate cleanly with the portal and each other.
