• Optimize performance, debug complex issues, and ensure strong observability.
• Develop high-quality, responsive web applications using React + TypeScript.
• Own customer-facing dashboards, campaign builders, reporting UIs, and supporting API layers.
• Work on internal tools, SSR/edge rendering, and lightweight Node.js services.
• Focus on performance, Core Web Vitals, and developer experience.
• Collaborate closely with Product, Design, and Engineering teams.
