Sandeep K.

I'm Sandeep, a full stack .NET developer based in India with 12+ years of experience building web applications and business systems that clients actually rely on day-to-day — not just projects that get delivered and forgotten. Over the years I've worked with startups, SMEs, and established businesses across industries like retail, logistics, healthcare, and services. Whether it's building something from scratch or jumping into an existing codebase, I get up to speed quickly and write code that the next developer won't curse. My core stack: ASP.NET Core / MVC · C# · SQL Server · JavaScript · jQuery · React JS · HTML5 · CSS · IIS · DevExpress · WPF What I typically help clients with: Custom web applications built on ASP.NET MVC or Core — from requirements to deployment Legacy .NET systems that need new features, bug fixes, or a full modernization SQL Server database design, query optimization, and reporting React or jQuery frontends wired to .NET backends and REST APIs Windows desktop applications in C# / WPF for internal business tools DevExpress UI components for data-heavy grids, dashboards, and forms IIS configuration, deployment pipelines, and server-side troubleshooting How I work: I don't just write code — I ask questions first. Before touching a keyboard, I make sure I understand what you're actually trying to achieve, not just what's written in the spec. This saves time, avoids costly rework, and means you get a solution that fits your real workflow. I communicate proactively. If something's going to take longer, or if I spot a better approach mid-project, I'll tell you — not after the fact.
