01. About Me

I'm a Principal Engineer at PT. Bangunindo Teknusa Jaya with a passion for building robust, scalable systems. My journey started as an Oracle Developer and evolved through backend development, technical leadership, and now engineering strategy.

I've had the privilege of working at Tokopedia (one of Indonesia's largest tech companies), building data pipelines for Telkomsel, and delivering systems for Indonesian government ministries.

Today, I define technical vision across the organization, lead architecture reviews, and mentor the next generation of engineering leaders. I specialize in distributed systems, database optimization, monitoring infrastructure, and cloud-native architecture.
