ProjectsShelfCast — Sales Analytics & Forecasting Dashboard ShelfCast is a sales dashboard focused on providing analytics and insights, including predicting future sales using an advanced forecasting algorithm. Originally built for a specific local business in Lethbridge, I have since expanded the project with the goal of making it scalable for any small business that has POS data. It can upload CSV exports from a POS system, parse and store sales data in a local SQLite database, generate visual reports (top sellers, worst movers, sales trends, and category performance), produce bulk forecast reports, and filter all reports by date range and category. Brezina Strength Academy A personal coaching website built using Wix and Figma to showcase UI/UX design with a focus on accessibility and full mobile accessibility. I developed prototyping skills and demonstrated live usability testing in front of a live audience, applying Steve Krug's principles for accessibility so users never felt lost or overwhelmed. Client's High-Performance Gaming Build An end-to-end gaming PC build for a client working with a $2,500 CAD budget, delivered fully assembled and tuned for roughly $2,200. I guided the client from the first conversation: scoping what was achievable within budget, defining target resolutions and frame rates, walking through theme options, explaining the reasoning behind every choice, flagging buying traps to avoid, and using the PSU tier list to verify the power supply was genuinely worth its price. I advised on the full peripheral setup, assisted with the physical build, performed a clean Windows installation, removed bloatware, and enabled XMP/EXPO.
