• Implement Vue 3 components inside an existing AngularJS application via an interoperability layer. • Contribute to incremental, page-by-page migration leveraging the strangler pattern. • Replace low-risk admin and user-facing pages first and progressively advance to higher-impact functionality. • Assist in defining patterns, conventions, and reusable core component designs that will scale across the entire platform. • Review developer-submitted design proposals for core shared components, ensuring consistency, maintainability, and performance. • Provide architectural guidance to prevent the proliferation of poorly structured components that would create long-term technical debt. • Establish Vue coding standards, folder structures, testing patterns, and best practices. • Work closely with two internal sprint teams to mentor developers who are new to Vue and TypeScript. • Offer pair programming, code reviews, live feedback, and hands-on training to increase team confidence and competency. • Help build internal capability so the EWM team ultimately owns and continues the migration independently. • Participate in sprint ceremonies (daily standups, sprint planning, retrospectives). • Collaborate closely with team leads, QA, and the architecture group to maintain high quality and velocity. • Provide proactive communication and documentation to ensure alignment within teams operating across U.S. time zones (primarily Central Time). • Contribute to test strategy, including unit tests, integration tests, and visual/UI testing where applicable. • Work effectively within a large monolithic application with significant static analysis tooling and C#/.NET backend integrations. • Help ensure delivered work meets quality expectations, reducing QA rework and avoiding the pitfalls of prior offshore engagements.
