I designed and built a native-language calling platform that tells customers their parcel has arrived. The client paused before contract, so it never ran in production.

Client: One of Southeast Asia's largest logistics networks (de-identified)
Role: I designed and built it through Ongkrong Consulting
Format: Automated native-language calling platform
Year and length: 2026, about 7 weeks

The brief

Branch staff phoned customers one at a time to tell them a parcel had arrived. An internal attempt to automate it had stalled, and the client wanted a working option.

Approach

I scoped a system that reacts to each parcel. A parcel is scanned at a branch, the platform hears about it, and a voice call goes out in the customer's language.

Showing a real local number on the customer's phone turned out to be a telecom job first. I ran a live tender across call platforms and local carriers. I set it up so no single vendor controls the whole system.

181 of 181 automated tests passed. I ran it at 20,000 calls at once: no errors, and 99 in 100 responses took 76 ms or less.

Outcome

The platform reached a contract-ready state in about 7 weeks. The client paused before signing, so it never carried production traffic and no saving was banked.
