# Institutional software engineering

Inside a large organization, the constraints come from the systems already running, the people who depend on them, and the rules the company answers to. The work is adding a capability without disturbing what the organization already relies on.

## Financial interfaces at American Express

American Express already had a frontend and a marketing machine, so I worked inside them. I shipped credit-card marketing components, comparison sliders, and landing pages, helped with the Dojo-to-jQuery migration, and ran A/B tests inside the analytics stack.

## Interactive media at AMC Networks

AMC's YEAH! launched at SXSW in 2013 with Facebook login required. The frontend I owned had to work with Facebook for identity and sharing, and with Brightcove for streaming, chapter playback, and back-office editing.

## A private chain for Grant Thornton

At EOS Costa Rica I built a private EOSIO chain for Grant Thornton: an MVP for intercompany transactions and tax workflows, with a stablecoin, hashing, and IPFS records behind a React client.

## Regulated banking and retail mobile

Wink depended on partner banks, so I coordinated with their teams and vendors on the API integrations that moved deposits, transfers, and account data through the app.

At Tractor Supply I came in as a consultant on an existing React Native app. I introduced TypeScript, improved performance, and built a ViroAR feature for product previews without replacing anything around it.
