I work on parcel transportation and ecommerce fulfillment: what shipping costs, why it costs that, and which decisions change it.
Career highlights
Results from the shipping and transportation product surface at ShipMonk, a third-party logistics provider whose network ships tens of millions of packages a year. More than 90 percent of that volume moves through the rating and routing I own.
- Annual carrier savings, delivered through 10 launches
$10M+
6 new carriers, 3 expansions, and 1 relaunch, all API integrations. Product lead on each, and on several the full launch, from negotiation data to rollout.
- On-time delivery, fixed by changing the math
50% → 90%+
Retail-compliance shipments missed their window half the time. Planning to 90th percentile transit, and getting the retailer to move the window off the weekend, fixed it.
- Hours of manual work eliminated a year
4,000+
Three production internal apps, built and shipped as a non-engineer, that centralized the Transportation team's operations, carrier management, and financial reporting.
- Hazmat order volume, 3 carriers to 6, same margin
~9×
I identified the flaws in the existing setup, designed the solution, and worked with engineering and operations to implement it. Volume grew almost ninefold, with margin held and carrier violations sharply down.
- Faster order to doorstep, at no added cost to the brand
50%
Cut click to delivery for ShipMonk merchant Dr. Squatch from 7-8 days to under 4 on economy orders, through order cutoffs, carrier selection, and method mix.
Portfolio
Tools for the decisions shippers have to make, like where to put the next warehouse or what a box choice costs. I build them with Claude Code on synthetic data, so the math can be public.
