Supply Chain & Data Toolkit

Nine small, focused tools that each solve one quick supply chain or data science problem โ€” the kind of recurring "micro-inconvenience" that rarely gets its own project but eats time every week. Built fast, with AI, to prove a point: I notice these bottlenecks, and I can go build the fix instead of just flagging it.

Why this exists

Most operations and data work isn't glamorous โ€” it's a dozen small decisions made well or poorly: when to reorder, how much to order, whether a supplier is actually reliable, whether that A/B test result is real. Each tool here targets exactly one of those decisions and makes it a ten-second calculation instead of a spreadsheet exercise nobody has time for. That's the kind of problem-solving I want to bring to a team: spotting the friction and removing it.

Grounded in coursework, not guesswork

The supply chain formulas in these tools (safety stock, reorder point, EOQ, ABC analysis) and the AI-native approach to building them both come from real coursework, not just a Google search:
