Project details

You will get a professional security audit for your .NET application focused on identifying vulnerabilities, reducing technical risk, and improving secure implementation. I review ASP.NET, Web API, .NET Core, and enterprise applications to detect security weaknesses in authentication, authorization, data handling, and exposed endpoints.

This service is ideal before production release, cloud deployment, enterprise onboarding, or compliance preparation where secure application behavior is critical.

My review covers authentication flow, role access, API exposure, input validation, secret handling, configuration risks, and common attack surfaces with practical recommendations for immediate improvement.

Visual Studio C# .NET SQL Issue Resolution Ajith was great to work with and incredibly knowledgeable. I’d highly recommend him if you run into any roadblocks like we did.

He helped us get a new ASP.NET C# project running in Visual Studio 2026 after moving from our older 2012 setup. We ran into several version‑related issues—scope errors, SQL connectivity, a small code bug, IE configuration, and publishing—but he walked us through all of it.

We wouldn’t have met our deadline without his expertise.
