Top SchoolJustin Griffith is a Principal Engineer with 11 years of experience building high-performance, data-driven systems and leading engineering teams from greenfield products to production-scale analytics platforms. He combines a strategist’s vision with hands-on expertise in Java (including Java 21), low-latency multi-threading, and portfolio analytics—having architected an HFT-style platform processing full equity market data and analyzed portfolios totaling nearly $1 trillion AUM. Justin has led cross-functional teams to modernize architectures, introduce microservices and monorepos, and deliver real-time query engines that power customer-facing analytics. Based in Texas, he blends product-first thinking with technical depth, often translating business strategy into reproducible developer practices and source-available tooling. A less obvious strength is his track record of founding and running a web dev shop, giving him practical startup intuition alongside enterprise engineering leadership.
