  • Continuously improve existing systems by refactoring code, reducing technical debt, optimizing performance, and reinforcing security practices.

  • Bachelor’s degree in Computer Science or equivalent practical experience.
  • Deep understanding of web and SaaS architecture patterns, including when and how to apply them effectively.
  • Hands-on expertise with Node.js and TypeScript in production environments.
  • Experience with cloud platforms, CI/CD pipelines, and container orchestration technologies.
  • Proven ability to assess and integrate emerging technologies into existing systems.
  • A strong focus on security, reliability, and operational excellence.

Nice to Have
