Summary
Kaley Sullivan is a senior backend and platform engineer with a decade of experience building resilient infrastructure and payments systems for high-growth startups. She has a strong track record of shipping large-scale features—from sharding Webflow’s largest tables and hardening migration tooling to designing Wave Mobile Money’s Checkout API and business model that unlocked millions of users. At Etsy she led the GraphQL rollout and improved developer experience through tooling, documentation, and workshops, and earlier work shows deep experience in ETL, experimentation, and reducing tech debt. She combines hands-on coding with systems-level design and a knack for turning complex migration and compliance challenges into auditable, testable solutions. Based in New Orleans, she’s also driven culture and process improvements, including LGBTQIA+ advocacy in international contexts and introducing better project management practices. Colleagues describe her as pragmatic, detail-oriented, and unusually adept at surfacing hard-to-find data issues before they affect customers.
