Founder · IAT Software · 2014–Present
Twelve years owning a research SaaS used at Oxford, Princeton, and high-school psychology labs. Currently rewriting the 600+ class WinForms client into a clean MVVM WPF application on .NET 10.
I design and ship production-grade software that researchers actually use. For twelve years I have owned the entire lifecycle of IAT Software — a SaaS platform that lets non-engineers create, deploy, and analyze Implicit Association Tests based on Harvard methodology.
I don’t chase frameworks — I ship maintainable, correct software.More about me

A ground-up rewrite of a 600+ class WinForms IAT authoring client into a maintainable MVVM WPF application. Designer tabs are in place; deploy lands with the coordinated server release.

Three-tier, message-driven Spring application that deploys user-authored tests, administers them in the browser, stores encrypted results, and emits Excel workbooks that routinely exceed 150 worksheets.

The full product: a point-and-click authoring environment, a server that administers IATs, Excel exports of Greenwald D-scores, and a public site.

The WPF rewrite is not a reskin. It is a set of rules the original client taught me the hard way.
The test model holds data and Guids. It does not touch the file system, the network, or the display. Side effects live in services. That boundary is the rewrite’s north star — learned the hard way from a WinForms client where god objects talked to everything.
WebSockets, packaging, image generation, validation, and dialogs are interfaces registered in DI. ViewModels consume contracts, not implementations. MediatR carries transaction events across that boundary so a handler never needs a window.
Instruction regions, continue strips, and keyed layouts are derived from the interior and key positions. Designers can override; the calculator still owns the defaults. Previews stay locked to the same aspect as the administered test — one math, two surfaces.
A socket that works once is a demo. Persistent connections, cancellation, exponential backoff, thread-safe send, and transaction completion without tearing down the pipe — that is production. UTF-8 text frames, not binary, because the Java handler is a TextWebSocketHandler.
