Top rated, very hands on, IT Systems Architect and Lead Developer with a proven track record that spans more than two decades in both the Private and Public sector. Legit out-of-the-box thinker with problem solving abilities that have consistently provided original innovating solutions or saved heavily invested ones from sinking.
** My 4.2 stars rating is only due to a 9-years old 100K project that was successful but the client only rated it 4.0, due to his particular style of being strict with ratings. This rating only took effect recently due to Upwork making the choice to include LIFETIME ratings. Without it, my overall stars rating would be 4.9**

Over 10 years of experience building full-stack web, desktop, and mobile applications — now extended with modern cloud-native stacks and enterprise AI automation.
✅ Strong in both Back-End and Front-End development
✅ Web Apps, Desktop Apps, iOS & Android Mobile Apps
✅ .NET ecosystem + Node.js + Python + Supabase
✅ AI Automation: Power Automate · M365 Copilot · Claude (Anthropic)
✅ Familiar with Vue3, ReactJS, AngularJS, Blazor, Bootstrap, Twilio, AWS S3, AWS Lambda, Dropbox API, SignalR, Google Maps API, Crystal Reports, Telerik Reporting
💼 CORE EXPERTISE
With over a decade of .NET experience, I have deep expertise in .NET Core, ASP.NET MVC, Web API, Microsoft Blazor, Entity Framework, WCF, and Xamarin — coding fluently in both C# and VB.NET.
I've recently expanded my stack to include Node.js and Python for modern API development and scripting, and Supabase as a scalable open-source backend (PostgreSQL, Auth, Storage, Realtime).
AI AUTOMATION — MY NEWEST STRENGTH
I design and implement intelligent automation workflows using:
Microsoft Power Automate — business process automation across M365, SharePoint, Teams, and 3rd-party services
M365 Copilot — AI-assisted productivity and enterprise integration
Claude (Anthropic) — custom AI integrations, prompt engineering, and API-driven automation pipelines
Build RAG chatbot and more.
This lets me deliver solutions that don't just work — they think and automate.
⭐ SPECIAL SKILL — SYNCFUSION
10+ years working exclusively with Syncfusion's 1,000+ component library across WinForms, WPF, ASP.NET, Blazor, Angular, React, Vue, Xamarin, and UWP. If it's Syncfusion, I can build it.
🏥 LONG-TERM PROJECT HIGHLIGHT
For 10+ years I've collaborated directly with a U.S. client on an Electronic Medical Records (EMR) platform — managing appointments, e-prescriptions via Surescripts, and integrations with Twilio, EFax, AWS S3, Dropbox, SignalR, Telerik Reporting, and Syncfusion. I have hands-on knowledge of U.S. healthcare standards: ICD, CPT, and HL7.
I write clean, well-tested code and always review my work before delivery. I take full ownership of every project I touch.
Let's talk about what we can build together.
