Description:

We are seeking a Senior .NET Developer (Contractor) to support the modernization of our enterprise web application. The ideal candidate will play a key role in converting our .NET Framework 4 (C#) web application to .NET 8 (Core), the latest version of Microsoft’s unified .NET platform, while enhancing system performance, scalability, and maintainability.

This role requires a developer with strong SQL Server expertise, capable of managing and optimizing databases independently. The candidate will also help design and integrate AI-driven functionality into our platform to enhance user experience and operational insight.

Responsibilities:

  • Migration of existing .NET Framework 4 web applications to .NET 8.

  • Refactor and optimize legacy code for improved maintainability and performance.

  • Collaborate with UI/UX and frontend teams utilizing modern JavaScript frameworks and libraries.

  • Manage and optimize SQL Server databases, including stored procedures, indexing, and performance tuning.

  • Assist in architecting and integrating AI and machine learning capabilities into the web platform (e.g., natural language processing, predictive analytics, or generative AI features).

  • Provide technical mentorship and guidance to internal development staff.

Preferred Skills:

  • Background in data analytics or AI model integration.

  • Familiarity with REST APIs, JSON, and web service integration.

Qualifications

  • 7+ years of professional experience in software development with a focus on C# and ASP.NET.

  • Proven experience migrating legacy applications from .NET Framework to .NET 8.

  • Proficiency in SQL Server, including query optimization, complex joins, triggers, and stored procedure development.

  • Hands-on experience with modern JavaScript libraries and frameworks (e.g., jQuery, React, or Angular).

  • Experience implementing or integrating AI/ML functionality (OpenAI API, Azure AI, or similar).

  • Strong analytical and problem-solving skills.

  • Excellent communication skills and the ability to work collaboratively within a small team.

Education:

  • Bachelor’s degree in Computer Science, Information Technology, or related field (or equivalent experience).
