What you’ll bring

• 2+ years of hands-on experience in full-stack development.
• Proven expertise with React (hooks, component architecture, state management) and modern JavaScript/TypeScript.
• Solid experience building RESTful services in Node.js with Express (or similar).

• Exposure to containerisation (Docker, ECS, EKS) or serverless architecture patterns.
• Prior work in health-tech or other regulated domains.
