Top SchoolJoshua L is a seasoned technology leader and current CTO with 17 years of experience building and simplifying high-scale platform, data, and infrastructure systems from Oakland, CA. He rose through engineering roles at EasyPost—shaping API, financial pipelines, and platform consolidation—and previously drove SRE, API, and data pipeline work at Fastly and Engine Yard. Joshua blends hands-on backend engineering (notably contributions to widely used Ruby projects like fog and RubyGems) with strategic product and financial alignment to improve throughput, reliability, and unit economics. He has a track record of deconstructing monoliths into service-oriented architectures, shipping low-latency logistics and verification systems using languages from Go and Rust to Ruby. Known for reallocating capital and teams toward higher-margin products, he pairs deep technical judgment with board- and executive-level partnership for enterprise readiness. His background in ECE from Worcester Polytechnic Institute and early work across QA, ops, and supervision give him a pragmatic, systems-oriented approach to scaling engineering organizations.
