I build resilient data and platform systems while leading engineering teams.
New ZealandWhat I'm looking for
I've built software engineering systems since 2015, from Indonesia to Aotearoa, New Zealand. At DKATALIS, I lead the architecture, design, and delivery of a modular, high-availability loan platform and a new payroll system for a fintech innovation lab serving millions of users.
At GovTech Edu, I led six data and backend engineers through a PostgreSQL-to-BigQuery re-architecture, improving data quality from 80% to 92%. I also led the migration of 500+ databases into a unified system and helped establish a faster one-week sprint cycle.
At Bukalapak, I led marketplace seller and revenue engineering teams across microservices and monoliths, improving resource efficiency by 20% and maintaining no incidents during three quarters of leadership. Earlier, I helped reduce Facebook ads data discrepancies for 400,000 promoted products from 70% to 20%, contributing to a 15–18% revenue increase.
I make the technical calls, write the code to support them, and mentor engineers as they grow. I care about reliable production systems, practical automation, resilient architecture, and AI-assisted workflows that help teams move faster.
