Olga Mazurenko

I’m a Senior Frontend Engineer with 7+ years of experience building production React applications. My recent work has focused on large, multi-tenant B2B platforms, including complex dashboards, scalable design-system UI, and data-heavy workflows. I work across the full frontend development lifecycle, from architecture and authentication/session flows to feature flags, analytics, testing, API integration, and CI/CD. My core stack includes React, JavaScript, Jest, Cypress, GTM, GA4, and some experience with backend API integration. I also have hands-on experience with Go. I’m particularly interested in engineering productivity and AI-assisted development. I’ve designed an engineering automation framework using Cursor Rules, Skills, and specialized agents to automate code reviews, enforce project conventions, and streamline development workflows across multiple repositories. I enjoy working on technically complex products where frontend architecture, developer experience, and maintainability matter as much as delivering features.
