Samuel Brian

At Komunal Indonesia, I lead engineering across a P2P lending platform and a Core Banking System for rural banks, managing 10–16 engineers and a dedicated QA team.

I led the company-wide migration from AliCloud to Google Cloud Platform, reducing server costs by 25–50% through cloud cost auditing and resource optimisation. I also introduced RFC-driven technical documentation, cutting spec-review turnaround and implementation time by 50%.

Previously, I improved stability across Komunal's platforms by reducing automated money-movement incidents by 90% and transaction error rates by roughly 65%. I’ve mentored engineers into senior and tech lead roles, helping squads operate independently.

My background includes building end-to-end products for Singapore-based clients, leading web projects, developing games APIs, and creating automated testing frameworks and CI pipelines. I’m a Google Professional Cloud Architect with 10+ years of experience across Indonesia, Singapore, and the Philippines.
