Doing a good job, when he's working, very difficult to communicate because of the time difference and because of that impossible to get some things done

Job Success
Mohali, India - 3:45 pm local time
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.
A bit of credibility:
Top Rated Plus on Upwork with a 100% Job Success Score
10+ years delivering projects across web and desktop platforms
Comfortable working independently or slotting into an existing dev team
Available for both short fixed-price tasks and longer ongoing engagements
If you have a project in mind — whether it's a clear spec or just a rough idea — send me a message. I'll give you an honest assessment of scope, timeline, and fit before we start anything.
