About

DENPASAR, BALI, INDONESIA
Portrait of I Gusti Made Agung Apriantara

My background is two decades deep in ColdFusion / ColdBox — the kind of stack that ages out of fashion but keeps running quietly in production long after launch day. The last several years have been about bringing that same architectural thinking to Go, PostgreSQL, React, and Next.js: modernizing legacy systems without breaking what already works for the people depending on it.

I'm most useful in the gap between "this needs to be built" and "this needs to still be running in five years" — scoping the work, designing the data and auth layer correctly the first time, and leading a small team through delivery while staying close to the client.

  • BackendArchitecture & API design — Go, ColdFusion/ColdBox, PHP, REST
  • SecurityAuth & access control — reusable RBAC used across multiple products
  • Full-StackDelivery — React, Next.js, legacy-to-modern migrations
  • LeadershipTechnical lead — scoping, small teams, direct client work
