Things I built, and what happened.

Building an itinerary platform advisor-first, where most of the hard problems turned out to be naming problems.

Took an invoice short-link service from design to production in two weeks, where most of the design work was the security analysis.

Co-owned the payments-domain rollout of an org-wide move to scoped permissions — and argued the scope grammar back toward least privilege.

Built the pricing calculation, reconciliation, and retry flows for dual pricing — a marked-up card price beside a base bank-transfer price, and the failure states that creates.

Primary author of the calendar, contacts, and gift recommendation systems that turned a one-shot purchase flow into a product with a reason to return.

Rebuilt fraud investigation as a decision surface rather than dashboards: throughput up 40%, the review backlog halved.

Replaced a spreadsheet with a service, and found roughly a quarter more available providers in the states that needed them most.

Took the password out of the buyer path, moved checkout state off the client, then shipped a multi-item cart — the cart last, because the cart was the easy part.

Built multi-place gifts: one card composed from several real businesses, for senders who know the person but not the place.

Two systems in one year: a dispute-handling pipeline that cut resolution time about 40%, and an IVR migration that lifted payments by phone 25%.

Led the rebuild of the buyer and recipient experience off three frontend eras onto Vue and Inertia, one flow at a time, for a 17.5% year-over-year conversion lift.

Cut the time to launch a new telehealth service line from three or four months to under one — then grew the team that used it from three engineers to eleven.

Designed a processor-agnostic payments architecture inside a large Rails monolith, and the service-module patterns that let teams work in it independently.

Led the rebuild of the ACH pipeline that moves money in and out — halving on-call load and closing a roughly $300k annual leak.
