Decision log

Three pieces of work from BTPN Syariah, Jakarta. In each I was product owner of a scrum squad of about ten: a scrum master, a tech lead, engineers and QA. I owned the roadmap and priorities, and dealt with business, compliance and users.

01 · Payments

Fixing bill payments that failed quietly

Senior Product Manager, transactions squad
2024 to 2025

90%fewer failed payments, roughly

Problem
I took over bill payments, transfers and top-ups in SiTepat, the bank's customer app. Some products could never succeed, because the provider had dropped them and the app still listed them.
Decision
We built dashboards for every product and provider, audited the whole product list, and set one rule: reroute when a provider is unreliable, hide when the fault is temporary, remove when the product is gone.
Trade-off
Rerouting was sometimes the less profitable option. We chose the payment that works.
Result
Failed payments fell from about 20 in every 100 to about 2, and the app sold only what it could deliver.

02 · Onboarding

A shorter sign-up for customers we already knew

Product Manager, onboarding squad
2021 to 2023

4 or 5steps cut from app sign-up

Problem
In the SiTepat pilot, every new user went through the same long sign-up, whatever the bank already knew about them.
Decision
After 40+ interviews, observations and A/B prototype tests, we added an ID scan that recognised people already registered as agents and gave them a shorter route.
Trade-off
Two routes are harder to build and maintain than one. Everyone else still got a simpler flow, with 4 or 5 steps removed.
Result
More people who started sign-up finished it. The pilot, run in three provinces, reached about 1,000 customers transacting every month.

03 · Field tools

Replacing paper forms for 10,000+ field officers

Product Manager, acquisition squad
2016 to 2019

40%less time to enrol a customer

Problem
Field officers enrolled new customers on paper. Every form was then typed into the system a second time.
Decision
We built a mobile tool that let officers enter details once, on the spot. I wrote the playbooks and trained staff across regions for the rollout.
Constraint
It was the officers' first digital tool, and it could not depend on a good signal in the field. We built it offline-first, so entries synced automatically once officers were back at the office.
Result
Enrolling a customer took 40% less time than on paper, measured from start and finish times. The second round of typing went away.

Recent projects in Melbourne

University team projects for real clients and briefs. My part in each was the research, the concept and the working prototype.

Real client · University subject

Women and Mentoring homepage redesign

The old page read like a small charity asking for help. I rebuilt it to lead with evidence of what the program achieves, with three hero variants ready for A/B testing in the client's existing site builder.

EcoSwap furniture marketplace

A landing page and working prototype for student furniture swaps. It runs on a real database and tracks events and scroll depth, so I can see how people use it.
