Case Studies
Most of my work lives behind enterprise walls, so instead of repos, here are the stories: the problem, the constraints, the architecture, the decisions, and what happened.
AI Call Analytics: Natural-Language Answers to 'Why Do Customers Call?'
Sole architect of a production AI pipeline that transcribed and classified about 10,000 calls per day for a multi-billion-dollar rental company. Its findings led to a product change that cut total call volume over 30%.
- ~10,000 calls/day ingested and classified
- Classification: hours to minutes with Batch Inference
- ~30% reduction in total call volume
- First production AI system at the client
Testing Against Production in Seconds: Module-Federation Override Tooling
Built a Webpack 5 runtime-override system and browser extension for a 60-micro-frontend platform whose lower environments did not match production. Developers could test local or branch builds against production conditions in seconds.
- 60 micro-frontends, 4 teams
- Production-parity testing: hours to seconds
- One-click dependency-aware deployments
The $1.4M/Year Bill Nobody Was Watching
A retailer's RFID loss-prevention POC emitted mostly false positives and cost about $119K/month on GCP. I replaced per-second label diffs with windowed SKU-set comparisons, modeled the cloud cost, and cut the bill by about 99%.
- ~$119K/month to ~$1.3K/month (~99% cut)
- ~10 valid events per 10,000 sent, before the fix
- $500–700M ROI opportunity sized in proposal
Being the Entire Product Team Across Two Fashion-Tech Businesses
Led architecture for a bespoke manufacturer and its digital tech-pack partner. I separated their shared AWS environment, decomposed one overloaded database into Tech Packs, WMS, and per-facility WES systems, and rebuilt the tech-pack application.
- 1 shared database to 3 purpose-built systems (Tech Packs, WMS, WES)
- Manual SSH deploys to CI/CD with health-checked cutover on ECS Fargate
- 95%+ of the tech-pack full-stack app built solo
The Batch Job That Was Silently Corrupting $10M/Day
Three months into the job, a self-directed audit of a 3-year-old Spring Batch validation pipeline found that only the first stop of multi-stop routes was evaluated. The same-day fix closed a $10M/day exposure.
- $10M+/day in losses prevented
- Silent defect: no errors, no alerts, 3+ years in production
- Found, confirmed, and fixed in one day
