Summary
👤
SeniorCharles Vien is a product engineer and founder with 12 years of experience building scalable systems and real-time platforms used by millions. He has led engineering from 0→1, architecting infrastructure that supported 10K+ concurrent users and shipping backend microservices through React frontends. As co-founder/CTO of gaming startups he scaled a Minecraft server to top-10 global player counts, implemented a hot-reload JS-on-JVM framework enabling sub-second deployments, and cut infrastructure costs dramatically via custom networking and Kubernetes orchestration. More recently at PostHog he’s building Array, a desktop orchestrator that turns product signals into actionable AI-driven tasks, and kickstarted a Unity SDK to expand games integrations. Comfortable across cloud ops, data pipelines, and real-time systems, he pairs deep systems engineering with a founder’s product instincts and a playful roots-in-gaming perspective that still informs his technical creativity.
