technologies used across these projects include PetaPoco, log4net, Twilio APIs, Selenium

WebDriver and integration with OpenAI’s ChatGPT service.

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.

Z.Dapper.Plus for bulk inserts.

• DEAVerification, a WinForms app automating data retrieval via Selenium

WebDriver and storing results with PetaPoco.

information using Selenium and logs results with log4net.

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

PDF generation with PdfSharp.

(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.

• 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 )
