Top SchoolEdwin Tunggawan is an engineering leader with 12 years of experience building cloud infrastructure, platform, VoIP, and security capabilities for fast-growing startups and scale-stage products. Currently AVP of Engineering at Cermati, he oversees infrastructure, platform, security, and GRC while previously architecting cost- and operations-efficient systems and automations that cut provisioning and ETL costs dramatically. He has a rare blend of hands-on IC work and team-building—assembling teams from scratch, defining roles, hiring, and mentoring engineers through multi-year technical roadmaps. Notable practical innovations include a JS-based company IAM framework, a Raspberry Pi–based graceful shutdown for on-prem call center servers, and automation that reduced access provisioning time by ~98%.
