• Develop supporting web interfaces and internal tooling using JavaScript and modern web frameworks
• Identify and deliver new app features with measurable business impact — from scoping to production
• Monitor app performance, crash reporting, and analytics to drive continuous improvement
• Ensure app security, data integrity, and compliance with platform guidelines (iOS \& Android)
• Collaborate with stakeholders to translate business requirements into technical solutions

• Understanding of mobile app deployment on Google Play Store and Apple App Store
