Hema Sri Kona

I’m a Senior .NET Developer with 8+ years of experience designing and building scalable web, desktop, and enterprise applications using Microsoft technologies. I focus on clean, maintainable architecture and high-performance implementations across the full SDLC.

In my recent role at Charter Communications, I designed and developed backend services using ASP.NET Core Web API and MVC, building secure RESTful APIs with JWT and OAuth 2.0. I work end-to-end with Angular for responsive SPAs, unit test frontend components with Karma/Jasmine, and support smooth deployments on Azure using CI/CD and IIS.

Earlier at Cygnet Digital, I modernized a legacy ERP by building a React-based frontend with TypeScript, Redux Toolkit, and React Query—reducing operational costs by ~$450K annually. I also delivered critical ASP.NET Core 8 Web APIs, built a WPF desktop application (MVVM) for warehouse teams in low-connectivity environments supporting 50+ distributed users, and optimized SQL Server performance to enable near real-time reporting on datasets exceeding 5M records.

I bring strong expertise in C#, LINQ, Entity Framework, NHibernate, and secure service communication (including WCF). I’m comfortable partnering with business teams for requirement gathering, applying design patterns, and delivering reliable solutions using Agile (Scrum) and Waterfall methodologies.
