Case Studies
Selected Case Studies
Expanded writeups for selected healthcare and product-engineering projects, with the confidential details generalized and the engineering decisions preserved.
These case studies turn the Impact highlights into fuller project narratives: the production problem, the technical approach, and the business result.
Performance engineering
Company-wide parser performance rewrite
A shared parser added seconds to large medical-service queries. I benchmarked the bottleneck, replaced expensive merge behavior with map-based lookup, and moved the parser toward predictable linear work.
- Representative workload
- 25s to 1s
- Measured parser speedup
- 25x faster
- User-facing load time
- about 80% lower
Reliability engineering
Nightly medical-service job stabilization
A nightly appointment-processing job looked healthy in production but silently left recoverable billable services behind. I rebuilt the run around bounded batches, caching, fault isolation, and categorized operational reporting.
- Recovered services
- about 5,300
- Failure boundary
- per appointment
- Run shape
- windowed and chunked
AI product prototype
Medical Coding Copilot
I prototyped an AI assistant for recording and processing billable medical services using an agentic workflow over case context, reports, tariff data, and deterministic validation.
- Workflow
- human in the loop
- Output
- structured suggestions
- Validation
- deterministic boundary
