Frontend Engineer at Octopus Energy
Tokyo, Japan
Summary
🎓
Top SchoolMary Sedarous is a frontend engineer with 8 years of experience building scalable, test-driven React and TypeScript applications from Tokyo. She has a proven track record delivering high-impact marketing and CMS integrations at Octopus Energy—owning A/B testing systems, analytics pipelines, and a server-side affiliates feature that measurably improved CTR/CVR—and previously rebuilt large, legacy React codebases at Comvex to modern hooks and TypeScript. Comfortable in fast-paced Agile teams, she pairs strong front-end expertise (Next.js, Gatsby, Redux, Zustand) with backend familiarity (Node, Express, PostgreSQL) and hands-on testing using Jest, Cypress and Playwright. Bilingual and academically trained at The University of Tokyo and UW–Madison, she blends product-focused collaboration (pair programming, marketing partnerships) with a curious streak for AR/VR, WebGL, and experimental side projects.
