Top SchoolDavid Gilbert is an experienced engineering manager and Java veteran with 21 years building high‑performance finance systems and a two‑decade history as an influential open‑source author. Based in Zurich, he has led teams at Datadog and SIX to deliver mission‑critical, low‑latency trading platforms and APIs, combining in‑memory grid architectures with robust Java clients and Oracle-backed persistence. Founder of Object Refinery and creator of widely used libraries such as JFreeChart, Orson Charts and JFreeSVG, he brings rare expertise in client‑side rendering, vector graphics and charting for both desktop and server environments.
