AI & API Connectivity: Assist in linking front-end components to AI WebAPI services and monitor service communication.
Application Lifecycle: Help track project statuses (Bid, Current, Archived) and implement versioning for elevation-level change orders.
Documentation: Maintain technical documentation for newly developed modules and deployment scripts.

Required Technical Stack

Core Frameworks: Deep expertise in C# and .NET Core (ASP.NET Core MVC, Razor Pages, or Blazor).
Database: Strong working knowledge of MS SQL Server 2022.
Cloud Computing: Hands-on experience with Google Cloud Platform (GCP) and its serverless offerings, particularly Cloud Run.
DevOps/Tools: Experience with Version Control (Azure DevOps/Git), and proficiency in deployment automation and scripting.
UI Components: Familiarity with DevExpress WinForms/ASP.NET Controls.
Development Environment: Visual Studio 2022.

Preferred Qualifications

Prior experience migrating legacy applications (e.g., WinForms) to modern web technologies.
Experience designing applications for high performance, utilizing cloud features like GCS for data handling, and supporting GPU-intensive operations.
Familiarity with containerization technologies (Docker/Kubernetes).
Domain and Application Knowledge (MillworkSuite):
Data Modeling & Integration: Experience implementing complex data models for product cataloguing, pricing tables, and customer-configured mapping to industry systems like Microvellum or Cabinet Vision.
Application Lifecycle Management: Familiarity with implementing project status workflows, versioning projects (e.g., Current, Bid, Archived), and tracking elevation-level versioning for change order (CO) costs.
Drawings and CAD Exports: Experience with drawing-related features, including managing revision sets, handling markers (e.g., PL1/PL2/SS1 pickup), and integrating CAD exports, specifically Cabinet Vision export.
Security & Audit: Experience implementing granular, feature-level role-based access control and an audit logging framework to capture key user actions (login/logout, edit, delete, approval, feedback).
Deployment Flexibility: Understanding of architectures that support both cloud/hosted and on-premise/limited-connectivity deployment modes.
