Technical Lead

Job Description Overview:

We are looking for a versatile Full-Stack UI Lead who can work hands-on to convert legacy ASP.NET Web Forms pages into a modern React Single-Page Application (SPA) while upgrading the supporting .NET Framework back-end to .NET 8. You will analyze existing .aspx pages and server/user controls, refactor them into reusable React (TypeScript) components or Razor/React hybrids, and integrate them with updated ASP.NET Core APIs.

Responsibilities

• Inventory, assess, and deconstruct existing Web Forms (.aspx, .ascx, master pages) to identify reusable UI patterns.

• Translate server/user controls into modular React components or Razor Pages with embedded React, preserving functionality while enhancing UX.

• Recreate simple, medium, and complex screensper the modernization backlog—ensuring feature parity and visual consistency. • Develop responsive React (TypeScript) pages that consume ASP.NET Core/.NET 8 APIs.

• Implement end-to-end data flows, validation, and error handling across UI, API, and database layers (SQL Server/Snowflake).

• Build and test feature-toggle mechanisms that allow safe side-by-side operation of legacy Web Forms and new React screens, enabling staged releases and quick rollbacks.

• Implement consistent theming, reusable design-system components, and accessible interactions (ARIA, keyboard navigation).

• Ensure high accessibility standards (ARIA, keyboard navigation, color contrast) and responsive behavior across common breakpoints/devices. • Present design decisions, prototypes, and sprint outcomes to business stakeholders and leadership, capturing feedback for continuous refinement
