⭐⭐⭐⭐⭐
✅ Top Rated by Upwork
✅ 100% Job Success
✅ 13+ Years Experience
✅ 85+ Successfully Completed Projects
I help businesses build, fix, modernize, and scale real-world software — not tutorial projects.
I’m a Senior .NET Developer & Architect specializing in ERP systems, SaaS platforms, eCommerce, and business-critical web applications.
What I actually do
• Design & develop ASP.NET / .NET Core applications that scale
• Build ERP systems — multi-tenant, role-based, report-heavy
• Create clean Angular & React frontends
• Customize & extend nopCommerce, Sitecore & Umbraco
• Integrate Microsoft Dynamics 365, APIs, payments & third-party services
• Modernize and troubleshoot legacy systems that “everyone else touched but no one owned”
AI-Augmented Development
I actively use modern AI engineering tools including ChatGPT, Claude, GitHub Copilot, Gemini, Cursor, and Windsurf to accelerate development and improve engineering decisions.
AI helps me with:
⚡ Faster code development & refactoring
🔍 Debugging and root-cause investigation
🏗️ Architecture exploration and technical planning
🧪 Test generation and code review
📚 Understanding unfamiliar/legacy codebases
🚀 Performance and optimization strategies
💡 Exploring alternative technical approaches
But AI is the accelerator — my 13+ years of engineering experience is the driver.
I don’t blindly copy AI-generated code. I review, validate, test, secure, and adapt it to the actual architecture, business requirements, and production environment.
Why clients stick with me
✔ I think like a business owner, not just a coder
✔ I ask the right questions before writing code
✔ I communicate clearly — no ghosting, no jargon flexing
✔ I deliver maintainable systems, not spaghetti miracles
✔ I use AI to work smarter and faster, without compromising engineering quality
If you want predictable delivery, clean architecture, modern AI-assisted development, and someone who treats your product like their own — let’s talk.
I don’t chase gigs. I build long-term wins.
