Partner closely with React/front-end teams to enable shared components, efficient state management, and system health visualizations.
•
Advance prototypes to production: transform algorithms or domain logic into well-tested, high-performance endpoints with solid observability.
•
Architect for resilience: address intermittent connectivity, graceful degradation, security hardening, and offline scenarios.
•
Drive quality and velocity: refine CI/CD, improve testing (performance, contract/property), and establish clear instrumentation and SLO/error budgets.
•
Mentor and influence: facilitate clear design narratives, code reviews, and integrate product and field feedback into the development lifecycle.
