I work on difficult systems: rescuing stuck projects, reverse-engineering legacy technology, and modernizing platforms. I move between people, architecture, and code to turn ambiguous problems into working software.

ELSEWHERE
THE WORK / 2015—PRESENTCOMPANY WORK & INDEPENDENT BUILDS

Work in
the real world.

From bank hardware to telemedicine,
with responsibility for people and code.

01.01 / CASH RECYCLING

Different devices.
One application.

Bank tellers’ cash transactions depended on third-party software. I owned the architecture and implementation of a device-agnostic replacement in Rust and React, with testing support from a predominantly non-developer team.

Two cash-recycling devices connect through adapters to one Rust application with a React teller interface and analytics.
10×devices per node — supported by simulator testing against the incumbent vendor solution’s known limits.
CONSTRAINT & APPROACH
Testing depended on physical cash devices. Built protocol simulators to test beyond the lab hardware, and adapters for two devices with room to add more.
TEAM & DELIVERY
Streamlined lab testing and releases with automated regression checks. Established documentation to retain knowledge and help new team members get started.
OUTCOME
Completed application, includes cash-usage dashboards, demand forecasts, and collection or replenishment recommendations.
One application. Three deployment modes.

Without additional development for each configuration.
