## Product & Engineering Work
### ProofMark · Client engineering contribution
Contribution completed
- Completed a client engineering contribution for ProofMark’s document-signing workflow, connecting identity, PDF fields, recipient routing and audit history. Across UI, APIs and data, made security-sensitive state and fallback paths explicit so signing and verification belonged to one traceable workflow.

### Kerf · Independent framework and UI toolkit
Early development
- Building Kerf, an early-development TypeScript/TSX framework with its own compiler, alongside its UI toolkit and routing, authentication and data services. Compiler-directed page updates and actionable diagnostics connect component architecture with feedback for coding agents; the framework is independent of React.

### NuPrice · Long-term client engagement
2019-2021
- For NuPrice, a long-term client engagement, built and operated a reseller application joining marketplace and competitor data with user-defined repricing rules. Connected accounts, subscriptions, billing and embedded support, then retained customer support and technical operations across the working product.
