Maroof K.

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 and worked on HIPAA COMPLIANT US HEALTHCARE ECHO SYSTEM (AUTH, SCHEDULING, EVV, PAYROLL, EDI BILLING) SUPPORTS MULTIPLE CLEARING HOUSES. 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 * Tkinter, openpyxl, pytest, and PyInstaller * SQL Server * REST APIs & GraphQL * Windows Services * Azure & Cloud Solutions * QR Code, Bar Code * COM | SERIAL PROGRAMMING ### 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 ✔COM/SERIAL DEVICES INTEGRATION **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.
