Jessie R is a self-taught, Linux- and open-source-rooted software engineer with 12 years of experience building full-stack systems across Python, TypeScript, PHP, Scala and big data tooling. With a mathematics background emphasizing pure math, probability and statistics, they bring a formal, probabilistic mindset to engineering problems—evident in past work on Bayesian impact measurement and data pipelines. Jessie has shipped front- and back-end features at scale, including contributions to Automattic’s high-profile wp-calypso repository where they implemented A/A tests and feature-flag integrations. Comfortable across cloud, container and legacy-modernization contexts, they’ve modernized codebases from Backbone/Marionette to React and led infrastructure and deployment efforts. An advocate of functional programming and Clojure, Jessie favors simple, principled solutions over quick fixes and is known for clear communication that bridges engineering and product. Based in Thailand, they pair hands-on delivery with a knack for turning complex statistical and platform challenges into pragmatic, maintainable systems.
