I build secure, production-ready AI, cloud and desktop applications on .NET, Azure and AWS — from intelligent document processing and AI agents to rich WPF and DevExpress business applications. With 15+ years of experience in enterprise .NET development, I bring AI into real business workflows: extracting data from documents, automating manual processes, and delivering polished desktop and web applications with proper security and access control. AI & Intelligent Document Processing ============================= - Azure AI Foundry (Microsoft Foundry): model deployment, prompt flows, agents and RAG solutions - Azure OpenAI / OpenAI GPT integration in .NET and Python applications - AWS Textract: extracting text, forms, tables and key-value pairs from PDFs, invoices and scanned documents - End-to-end document pipelines: S3/Blob upload → Textract/AI extraction → validation → database/API - PDF parsing, OCR and data extraction automation - AI chatbots, assistants and workflow automation WPF & DevExpress Desktop Development =============================== - WPF applications using MVVM, data binding, styles/templates and custom controls - DevExpress WPF controls: GridControl, TreeList, Charts, Ribbon, Docking and editors - DevExpress Reporting (XtraReports): report design, sub-reports, export to PDF/Excel and print - DevExpress components for ASP.NET Core and Blazor web applications - Modernising legacy desktop apps: .NET Framework to .NET 8, performance tuning, UI refresh - Integrating desktop apps with Web APIs, Azure services and AI features Azure Security, Identity & RBAC ======================== - Azure RBAC: role assignments, custom role definitions and least-privilege access across subscriptions, resource groups and resources - Securing AI resources (Azure OpenAI / AI Foundry) with RBAC and Managed Identities instead of API keys - Azure Policy and Conditional Access configuration and automation (PowerShell / Azure CLI) - Microsoft Entra ID (Azure AD), OAuth 2.0, OpenID Connect, JWT - Okta Identity Platform integration - API security with Azure API Management and Key Vault Core Technical Skills ================= Backend: .NET Core / ASP.NET Web API / C#, Python Desktop: WPF (MVVM), DevExpress WPF, DevExpress Reporting Frontend: ReactJS, Blazor, HTML5, Bootstrap Azure: AI Foundry, Azure OpenAI, App Services, Functions, APIM, Key Vault, Blob Storage, Entra ID AWS: Textract, S3, Lambda, EC2, SQS, SNS, IAM Database: SQL Server, PostgreSQL, MongoDB, Oracle What I Can Do For You ================= - Automate document-heavy processes (invoices, forms, contracts, reports) using AWS Textract or Azure AI - Build AI-powered features, agents and chatbots with Azure AI Foundry and OpenAI - Develop or modernise WPF desktop applications with DevExpress controls and reporting - Design secure Azure environments with proper RBAC, Managed Identities and Policy - Build scalable Web APIs and microservices in .NET Core - Implement authentication and authorization (Entra ID, Okta, OAuth2) Recent Work Highlights ================== - Built document-processing pipelines with AWS Textract to extract structured data from PDFs and scanned files - Delivered AI solutions on Azure AI Foundry integrated with .NET backends - Developed WPF business applications with DevExpress grids, dashboards and reports - Implemented Azure RBAC and least-privilege access models for cloud and AI resources - Automated Azure Conditional Access and named-location updates via scripts - Long-term full-stack .NET Core & React development for client web portals (5+ years, 2020–2026) Why Work With Me ============== - 3,000+ hours and 5.0 rating on Upwork - I think about architecture, security and cost — not just getting features to work - Clear communication and on-time delivery, as my client feedback reflects If you need AI built into a secure, scalable .NET, desktop or cloud solution, send me a message — let's discuss your project.
