  • Designing and developing secure applications by applying secure coding principles, OWASP guidance and security best practices.
  • Strong problem‑solving skills and the ability to work independently or within a collaborative team.
  • Ability to manage multiple priorities and deliver high‑quality solutions within agreed deadlines.
  • Good knowledge of HTML, CSS, JavaScript and experience with a modern front‑end framework such as Vue to support full‑stack collaboration.
  • Jira or similar Agile project management tools.
