ASP.NET Development: Enterprise Solutions with Proven Results

My ASP.NET journey began at Callaway Golf and UpperDeck, where I built robust e-commerce platforms and interactive web applications. This foundation in enterprise development shaped my approach to creating scalable, maintainable solutions that deliver measurable business value.

Technical Proficiency and Business Impact

My ASP.NET expertise spans both C# and VB.NET implementations, with a focus on creating systems that solve complex business challenges. At Callaway Golf, I developed components for their online store while integrating merchant services and inventory management. At UpperDeck, I helped build the digital companion for their Marvel Vs card game, combining ASP.NET with PostgreSQL for a rich user experience.

Notable Projects

My ASP.NET experience includes several significant projects that demonstrate the breadth of my capabilities:
