  • Strong proficiency in JavaScript (ES6+) and TypeScript across both frontend and backend (Node.js).
  • Hands-on experience with at least one modern frontend framework: React or Angular .
  • Solid understanding of HTML5, CSS3 , and modern responsive design techniques.
  • Design-heavy experience with a portfolio of public-facing sites that demonstrates strong visual design sensibility, attention to detail, and user-centered thinking.
  • Experience designing and consuming RESTful APIs ; familiarity with JSON and standards.
  • Proficiency with SQL and experience with relational databases (PostgreSQL or MySQL).
  • Experience with Git and GitHub Flow workflows on GitHub.
  • Understanding of Agile methodologies and tools (Jira, Confluence).

Preferred Qualifications
  • Experience building and deploying Azure Static Web Apps .
  • Hands-on experience with a headless CMS (Contentful, Strapi, Sanity, Sitecore, or similar).
  • Familiarity with Azure cloud services.
  • Experience with CI/CD using GitHub Actions and applying GitOps principles.
  • Practical use of GitHub Copilot in day-to-day development.
  • Experience working in GitHub Codespaces or similar cloud development environments.
  • Familiarity with GitHub Advanced Security (CodeQL, secret scanning, Dependabot alerts).
  • Exposure to NoSQL databases (MongoDB, DynamoDB, Redis).
