I help businesses build and modernize enterprise software that integrates seamlessly with complex business workflows. I have 15+ years of professional experience, I've delivered WINDOWS DESKTOP applications, ENTERPRISE WEB platforms, POS, KIOSK, ERP, backend services, workflow automation, and integration solutions for clients across the USA, UK, and Australia. My focus is solving complex engineering problems where reliability, scalability, and maintainability are critical. I specialize in Software/Tool development using .NET Framework and .NET Core. Alongside enterprise development, I help organizations adopt AI where it delivers measurable value. I build intelligent document processing, Retrieval-Augmented Generation (RAG) systems, AI agents, semantic search, OCR pipelines, and workflow automation using Azure OpenAI and modern LLM technologies. My approach is practical: AI should improve productivity and business processes—not simply add complexity. ### Core Expertise ✔Enterprise Software Development * C#, .NET, ASP.NET Web Form, ASP.NET Core, Blazor * WPF, WinForms, .NET MAUI * Entity Framework Core * SQL Server * REST APIs & GraphQL * Windows Services * Azure & Cloud Solutions * QR Code, Bar Code ### Industry Experience ✔ AI & Intelligent Automation ✔ Transport & Fleet Management ERP ✔ Healthcare & Medical Billing ✔ Retail POS & Inventory Management ✔ Payroll & Attendance Systems ✔ School & College Management ✔ Manufacturing & Industrial Automation ✔ Financial & Invoicing Solutions **Desktop & Hardware Integration** * Windows API * USB & Serial Communication * Driver Communication * Industrial Equipment Integration * Label Printers, Barcode Scanners, Weighing Scales * Smart Card & ID Card Printers **Healthcare EDI Solutions** * ANSI X12 * EDI 837P / 837I * EDI 835 * EDI 277 * EDI 999 * Healthcare Billing Systems * Clearinghouse Integrations **Biometric & Attendance Systems** * ZKTeco * eSSL * Mantra * Cogent * Suprema * Safran * Fingerprint SDK Integration **Technical Publications & XML** * S1000D * DITA * XML * XSLT * BREX * Data Modules * Schema Validation * Publishing Automation **AI & Intelligent Automation** * Azure OpenAI * Large Language Models (LLMs) * Retrieval-Augmented Generation (RAG) * AI Agents * Semantic Search * OCR * ETL * Document Intelligence * Workflow Automation If you're looking for a senior engineer who can understand complex business requirements, modernize legacy systems, integrate enterprise technologies, and deliver production-ready software, I'd be glad to discuss your project.

I help companies stabilize, modernize, and extend production .NET applications. I am a senior .NET and C# developer with 13 plus years of experience working on existing enterprise codebases in C#, ASP.NET Core, ASP.NET Web API, SQL Server, Azure, Angular, and React. Most of my work is not greenfield. It is the hard part. Legacy .NET Framework apps, slow APIs, fragile integrations, performance bottlenecks, data issues, and new features that need to ship without breaking what already works. I am comfortable with long running projects, messy code, and complex business logic. If you need someone who can step into an existing system and make safe, useful changes, that is the work I do best. What I can help with ASP.NET Core, C#, and .NET backend development REST API development, third party integrations, authentication, and background jobs Legacy modernization from .NET Framework, ASP.NET MVC, and Web API to modern .NET SQL Server schema design, stored procedures, query tuning, and data fixes Azure deployments, Azure DevOps, CI CD, and production support Angular or React front ends integrated with .NET APIs Bug fixing, refactoring, performance tuning, and scaling existing systems When AI is actually useful, I also build AI workflow automation and RAG systems inside existing .NET applications. That includes OpenAI API integrations, document extraction, internal knowledge search, summarization, approval workflows, logging, fallbacks, and human in the loop review.
