Presentation
My core strengths are C# / .NET, ASP.NET, MVC, SQL (MSSQL, MySQL), and backend system design. I have extensive experience modernizing legacy systems, building APIs, developing internal enterprise platforms, and improving operational efficiency through automation and system integration.
I have worked in large enterprise environments (including Accenture Interactive projects) and understand the importance of clean code, security, scalability, and clear communication. My solutions have helped companies reduce processing time, cut costs, and meet regulatory and security requirements.
I am currently based in Ontario, Canada, and available for freelance or contract work, including:
- Backend & full-stack development
- System modernization & legacy migration
- API integration
- Database design & optimization
- Internal tools and business systems
I value long-term client relationships and always focus on delivering practical, high-quality solutions on time.
