Four anonymized engagements with enough detail for engineering managers to compare against their own constraints.
Regional banking
Engineers missed instructor cues when scrubbing long replays; support tickets spiked after each release week.
We mapped DOM signal layers to audio peaks and shipped a narrow UI that jumps to annotated beats only.
Median time-to-answer dropped without adding surveillance hooks; compliance signed off on the data diagram.
Retail media
Webpack-to-Vite demos froze on underpowered loaner laptops during hybrid sessions.
Capped dependency graphs, pre-warmed caches, and split visual diffs from logic in pull requests.
Office hours queues shortened while satisfaction stayed level versus the gamified queue experiment.
Healthcare scheduling
Students copied verbose error strings that broke mobile keyboards and confused screen readers.
Schema-first Zod handlers with mirrored server messages and two-clause caps on client copy.
Accessibility audits passed earlier; mentors spent less time rewording validation text.
Design tooling startup
Graduates shipped rainbow-heavy projects that failed hiring bar on contrast.
Cool-palette generators with WCAG ramps and exception requests backed by measured contrast.
Demo day panels looked cohesive while individual taste still read in typography choices.
