·        Drive improvements in test coverage, accessibility, and user experience consistency.

12 Months

·        Act as technical owner for a full product line.

·        Deliver consistent, on-time releases with high quality and measurable performance gains.

·        Shape roadmap decisions with engineering leadership, balancing velocity and maintainability.

Core Outcomes & Metrics

·        Delivery Predictability: Stories committed vs. achieved, with stable sprint throughput.

·        Quality: Reduction in escaped defects, improved coverage, consistent review cadence.

·        Performance: Faster load times, smoother mobile interactions, efficient builds.

·        Engagement: Positive feedback from peers and stakeholders; visible growth impact.

What You’ll Do

·        Design, build, and maintain performant, reusable, and reliable front-end and cross-platform components in React, Xamarin/Maui, and .NET.
