• Strong expertise in Next.js, React, TypeScript, and ES6+ JavaScript

• Hands-on experience with Google Apps Script for automation and integrations

• Solid background in RESTful API design, development, and consumption

• Experience integrating third-party APIs and services

• Familiarity with cloud platforms (GCP, AWS, or Azure)

• Exposure to CI/CD pipelines and DevOps practices

• Strong experience with Git and collaborative version control workflows
