The problem
Supply chain work runs on formulas such as safety stock, EOQ, reorder points, and landed freight cost. Most people still work them out in spreadsheets they rebuild for every job. I spent my career in supply chain, and I wanted the tools I wished I'd had.
What I built
Freight Mode Estimator
Compares ground, ocean, and air freight on cost, transit time, and the inventory carrying cost of slower shipping.
Linked calculators
Calculators share their inputs, so a safety stock result can go straight into a reorder point calculation.
Scenario comparison
Put what-if scenarios side by side and compare the results before making a decision.
Glossary and acronym lookup
281 terms plus an acronym search, for students and for new hires who keep hearing "MOQ" and "DIO" in meetings.
Under the hood
- 32 calculators across nine categories, from inventory planning and logistics to procurement, ecommerce, and pay.
- Common supply chain formulas checked against what I know from working in the field.
- Pages are served as ready-made HTML with the styling built in, and the JavaScript loads afterwards, so pages show up quickly.
- Dark, professional design for people who keep it open all day at work.
What it shows
- Deep industry expertise turned into a product
- A system of tools that share data
- Performance tuning on a single-page React app
