Who I Am

Hi, I'm Ferdian — though online I go by ifkarsyah, my last name, because "Ferdian" is one of the most common names. I'm Indonesian, born and raised in the same country that gave the world Bali — though the archipelago has a lot more to offer than that one island.

I'm a software engineer focused on data platforms and infrastructure. I build the systems that ingest, process, store, and serve data at scale: streaming pipelines, OLAP clusters, data lakehouses, and the orchestration that ties them together.

At StraitsX, I focus on cost optimization and modernizing legacy snapshot pipelines into real-time streaming systems. Before that, at Xendit, I helped build the data engineering foundation from scratch — pipeline frameworks, infrastructure automation, and the tooling that let a growing team move fast without breaking data.

I studied Computer Science at Institut Teknologi Bandung (ITB). A Database Systems class there lit the spark — understanding how query engines work under the hood set the direction for everything I've built since.

I care about reliability, observability, and making data trustworthy — because dashboards built on bad data are worse than no dashboards at all.

Beyond code, I'm quite a traveler — visited around 20 countries so far, exploring new cultures, cuisines, and experiences. I share my travel stories on Langkah.
