• Modernise and replace legacy systems — including migrating older Angular applications to our current Vue and Nuxt stack.
• Own full-stack projects end-to-end, from specification refinement through delivery to production monitoring.
• Collaborate with product managers, architects, and cross-functional teams to gather requirements, assess technical feasibility, and determine the best implementation strategy.

• Write clean, maintainable, and efficient code, and uphold engineering best practices across the team.
• Ensure the quality of delivered solutions through robust testing and review.
