Heri Susanto · Jakarta, Indonesia
I design distributed systems and lead the engineers who build them. Shipping data infrastructure, fraud prevention, and government-grade platforms across Indonesia.
My work sits at the intersection of systems architecture and people. I care as much about the shape of a database query as I do about how the engineer writing it is growing. The best infrastructure, in my experience, is the kind no one has to think about, and the best teams are the ones that make that possible.
I started my career as an Oracle developer, spent time building end-to-end data pipelines for Telkomsel, and shipped fraud prevention systems at Tokopedia (one of Indonesia's largest e-commerce platforms). Today I define technical direction across 39 engineers delivering systems for Indonesian government ministries.
What I'm focused on now: system reliability, engineering culture, mentoring the next wave of technical leaders, and the unglamorous work of making complex infrastructure boring.
An operations dashboard for the ministry's core workflows. Tuned PostgreSQL for zero-downtime operation under sustained load, and shipped proactive monitoring with alert triggers so incidents are caught before they reach users.
A public-facing landing page and internal dashboard built on PHP and React. Redis-backed caching and queue workers behind Nginx kept the platform responsive through launch traffic.
A fraud prevention system protecting one of Indonesia's largest e-commerce platforms. Built in Go with NSQ for message queues, a React frontend for investigators, and Elasticsearch for forensic search across events.
Designed and built an end-to-end data pipeline for Indonesia's largest telco. Kafka for streaming, ClickHouse for analytics at rest, and Apache NiFi orchestrating the data flow between them.
