• Optimize performance, debug complex issues, and ensure strong observability.

• Develop high-quality, responsive web applications using React + Type Script.
• 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.
• Ship end-to-end functionality with a clear focus on quality, reliability, and speed.

• CI/CD practice with Git Hub Actions.
• Interest in B2B SaaS, sales tech, or automation tools.
• Basic exposure to full-stack work, even if your focus is mainly Backend or Frontend.
