Top SchoolTim Glaser is a founder and full-stack engineer with 10 years of experience, serving as CTO/co‑founder at PostHog and contributing broadly to its flagship open-source analytics platform. He pairs front-end polish—implementing UI components, pricing pages and documentation—with backend work in Python, JavaScript and TypeScript, shipping features like annotations, demo data for Hogflix, and API/performance fixes. Tim has hands-on experience with session recording, autocapture, feature flags and integrating observability tools such as Sentry, demonstrating a pragmatic focus on product reliability. Equally comfortable editing docs and tweaking CSS as he is diagnosing backend performance, he brings a product-minded design sensibility to infrastructure-level problems in a widely used open-source project.
