Highlights

Notification service

Designed and built a scalable notification system that integrates with multiple providers, with a retryable mechanism and logs for reliability. Clean architecture separates business logic from the interface layers.

Automatic donation system

Lets users schedule donations like an auto-debit, at daily, weekly or monthly intervals and at specific times, including the popular 5 AM "sedekah subuh". It had to scale with user growth: processing 30k donations first took 2 hours, which hurt at peak times. Asynchronous processing with RabbitMQ handled 80k donations in 1.5 hours, and early execution of steps plus batching with goroutines brought the run down to 1 hour.

Kitabisa Saling Jaga

A new product: a Sharia insurance platform where users contribute to a pool intended to help others in times of need.

Key-value configuration system

A centralized configuration service with a dashboard, so configuration changes take effect in real time without a deployment.

Operations Slackbot

A Slackbot that lets the operations team update user data and status efficiently.

Android app

In 2019, developed the Kitabisa.com Android app in Kotlin, moving it off a React Native build, and set up its CI/CD pipeline on CircleCI.

Activity

After my full-time role ended in July 2023, I continued backend work on the platform part-time as a freelancer, alongside other work, until June 2025.

The full role history is on the experience timeline.
