Senior🎓
Top SchoolDrago Crnjac is a Senior Software Engineer with nine years of experience building scalable web and data systems, now contributing to RevenueCat while running two product-focused companies. He founded SaaS Custom Domains to simplify secure, low-latency custom domain provisioning with a focus on 99.999% uptime and automated certificate management, and runs White Shores Tech delivering Ruby on Rails solutions on AWS/Heroku/Render. His background spans product engineering and leadership at SparkLoop and Intercom, plus hands-on work in machine learning-driven malware detection and Android reverse engineering early in his career. Drago combines deep systems and infrastructure know-how with product-driven entrepreneurship, often owning both the technical stack and customer-facing reliability guarantees. Based in Dublin with a master’s in Computer Science, he’s comfortable moving from architecture and data engineering to shipping production APIs used by global SaaS customers. A less obvious strength is his breadth: from low-level Android runtime analysis to high-availability distributed services, he bridges research curiosities and production-grade execution.
