Dot net Developer

Responsibilities

• Enhance and maintain our main web application, ASCLOGS, built on ASP.NET MVC
  
  

(.NET Framework 4.8) with features such as authentication, PDF generation via

IronPdf, audit logging with log4net, Twilio SMS integration, and data access through

PetaPoco.

• Support multiple companion projects including:
• CopyForm, an MVC tool that copies form templates between SQL Server
  
  

databases using AJAX and PetaPoco data access.

• SQLImportApp, a WinForms importer leveraging ExcelDataReader and
  
  

Z.Dapper.Plus for bulk inserts.

• DEAVerification, a WinForms app automating data retrieval via Selenium
  
  

WebDriver and storing results with PetaPoco.

• UniversalScrapperAPI, an ASP.NET Web API that scrapes licensing
  
  

information using Selenium and logs results with log4net.

• HL7DocAssistantSync, a VB.NET library for HL7 message processing and
  
  

PDF generation with PdfSharp.

• ChatGPT Implementation, a .NET 8 Web API example showing how we
  
  

integrate with OpenAI's ChatGPT service.

• S3MicroService, a .NET 8 Web API using AWS SDK packages
  
  

(AWSSDK.S3, AWSSDK.Extensions.NETCore.Setup) and Entity Framework

Core for storage.

• Maintain PowerShell utilities used for onboarding tasks such as document-to-PDF
  
  

conversion and CSV generation.

• Review existing code to improve reliability, enhance testability, and refactor large
  
  

code files (for example, BusinessLayer/BusinessLayer.cs is roughly 28k lines).

• Work closely with stakeholders to gather requirements for new features and ensure
  
  

compatibility with our SQL Server backend.

• Assist in modernizing legacy components and implementing best practices for
  
  

security, error handling, logging, and deployment automation.

Required Skills

• 10+ years of development experience
• Extensive experience with C# and the .NET ecosystem, including both legacy .NET
  
  

Framework and modern .NET Core / .NET 8.

• Solid understanding of ASP.NET MVC, Web API, and Windows Forms development.
• Familiarity with PetaPoco, Entity Framework Core, and SQL Server.
• Experience integrating third-party services such as Twilio, OpenAI, Selenium
  
  

WebDriver.

• Ability to write and troubleshoot PowerShell scripts for automation tasks.
• Comfortable navigating large codebases and improving code quality through
  
  

refactoring, unit testing, and documentation.

• Proficiency with version control (Git) and the Visual Studio toolchain.
  
  

Preferred Skills

• Background in healthcare or regulated industries, since many applications manage
  
  

sensitive data (e.g., DEA verification, HL7 messaging).

• Knowledge of PDF generation libraries (IronPdf, PdfSharp) and logging frameworks
  
  

(log4net).

• Experience with CI/CD pipelines for .NET applications.
• Nice to have Unit Testing frameworks (i.e. NUnit, MS Testing Framework )
  
  

Location & Work Environment
