01 / The Problem

Operational friction before the fix

Separate teams had optimized their own screens, but the overall process had no connective tissue. Important decisions disappeared at the boundaries.

02 / The Solution

Clear boundaries & status visibility

I worked across business and technical teams to define shared entities, lifecycle rules, and integration touchpoints — then delivered the screens that made those rules usable.

Key Operational Highlights

  • Facilitated process discovery with production, maintenance, and planning teams.
  • Defined UML models and API contracts that survived scope changes.
  • Improved clarity around SAP-linked operations and ownership.

03 / Code & System Architecture

How a business operates and how software responds.

The interesting part is rarely the syntax alone. It is the contract between the domain model, the UI, and the people who maintain the system.

fun releaseWorkOrder(orderId: String): ReleaseResult {
  val order = workOrder.findRequired(orderId)
  policy.assertCanRelease(order)
  val released = order.release(clock.instant())
  eventBus.publish(WorkOrderReleased(released))
  return ReleaseResult.success(released)
}

The detail is intentional: readable boundaries make reliable collaboration possible.
