Hello Client, Greeting of the day!!!! I read your job description. I can do this job with quality product. I am always available for your support. Thanks

@ajittkumark

I have 6+ years of experience in .NET development, working on business applications, APIs, and production systems where ongoing support, feature enhancement, and stability were equally important. My technical experience includes • ASP.NET and C# for backend development and business logic • SQL Server for query optimization, indexing, and production data handling • REST API development and third party integrations such as payment and external services • Frontend support using HTML, CSS, JavaScript, and structured UI changes • Authentication and secure API communication • IIS deployment and production troubleshooting on Windows environments My usual approach in live systems is to first understand the current architecture, identify recurring pain points, and then work in small safe changes so bug fixes and enhancements remain stable in production. This can cover bug fixing, performance tuning, payment or logistics integrations, database improvements, and new module development based on business needs. I am comfortable starting with a task based engagement and continuing long term if the collaboration fits well.

I’m comfortable working with existing codebases, IIS deployments, and jumping into urgent fixes when needed.

@bloginfinite25

A live ecommerce system with real customers going through it every day isn't the place for a developer who needs time to "get familiar" with production environments. You need someone who can jump in, diagnose fast, and fix cleanly without breaking anything else in the process. ASP.NET, C#, SQL Server, REST API integrations — this is my daily stack. I've worked on live ecommerce platforms where a slow query or a failed payment gateway call costs real money by the minute. I know how to move quickly without being reckless. Bug fixes, performance improvements, third-party integrations, new module development — I handle all of it. And I document what I do so your system doesn't become a black box that only I understand. IIS deployment, Windows Server, authentication systems, secure API integrations — comfortable with all of it. Frontend support in HTML, CSS, and JavaScript when needed too. I'm also genuinely interested in the long-term support side of this. A developer who already knows your codebase is worth far more than starting fresh every time something breaks. There's something about how your system is currently described that raises a flag I'd want to check immediately before touching anything — message me and I'll tell you exactly what it is. Could be nothing, could save you a headache. Open to negotiation — happy to start with a small task and prove it through work. Reach out directly and I'll share my portfolio and relevant work personally.
