About You:

• Expertise in JavaScript frameworks like React, Vue.js, or Angular, with proficiency in HTML, CSS, and responsive design principles.

• Strong experience with Node.js, Express.js, and building RESTful APIs or microservices.

• Proficiency in working with both SQL (PostgreSQL, MySQL) or NoSQL (MongoDB) databases.

• CI/CD & DevOps: Experience with integrating automated tests into CI/CD pipelines (e.g., Jenkins, CircleCI, GitLab CI) and familiarity with containerisation tools like Docker.
