Hi, I’m Tri Ahmad Irfan

Currently, I’m the Co-founder & CTO of Lumina (YC W22), a community-based job platform in Indonesia, growing into 1 million users in 6 months.

Previously, I served as VP of Engineering at GudangAda where I built high-performing technology teams from scratch. GudangAda is Southeast Asia's biggest B2B marketplace, with $135m+ raised from Sequoia Capital, Falcon Edge, Asia Partners, and Alpha JWC.

Prior to GudangAda, I was part of the founding team at STOQO where I helped built the core products and scaled the engineering team from 1 to 40 in three years. The company raised funding from top VCs in the region (Accel Partners, Monk's Hill Ventures, Insignia Ventures, and Alpha JWC Ventures).

Previously, I worked at Twitter in San Francisco and at several fast-growing startups in Indonesia (GDP Labs, Dekoruma, Cermati). I was a competitive programmer throughout my high school & university years and coached students who then won medals at national & international levels.
