Quality Assurance: Write unit tests and participate in CI/CD workflows to ensure the reliability of production code.

The ideal candidate must have the following experience, background, and credentials:

2 - 5 years of professional experience in software development, with a proven ability to work in frontend frameworks like React and backend ecosystems such as Java/Spring, C#/.NET, or similar enterprise-grade languages
Strong experience developing front-end applications using HTML, TypeScript, and CSS with a focus on responsive design and modern UI/UX
Strong understanding of RESTful APIs, React component design and common component libraries, and secure web development practices
Proficiency in writing unit tests using frameworks such as Jest
Experience working in a collaborative code environment and familiarity with Git, CI/CD pipelines, and modern development workflows
