## Target role
Senior Front End Engineer | Lively

## Profile
I build interfaces as part of the whole product: the data, access rules and support work matter as much as the screen. My work brings together React client delivery, a pricing application I operated end to end and an early-stage TSX framework of my own.

- HTML/CSS & reusable UI architecture
- Node.js APIs & PostgreSQL
- Authentication & integration workflows
- Production troubleshooting & AWS

## Product & Engineering Work
### ProofMark · Client engineering contribution
Contribution completed
- For a client document-signing product, I designed the workflow across identity, PDF fields, routing and audit history, using React/Next.js alongside APIs and PostgreSQL. My completed contribution joined the interface to verification and explicit fallback paths, experience I would bring to sensitive account flows.

### Kerf · Independent framework and UI toolkit
Early development
- Kerf is my early-development TypeScript/TSX framework: I am building its compiler, reusable UI toolkit and routing, authentication and data layer. The preview describes direct page updates and actionable diagnostics for coding agents. It is where I work on maintainable UI architecture, separately from my React work.

### NuPrice · Long-term client application
2019-2021
- At NuPrice, a long-term client engagement, I built and operated the application connecting marketplace data and pricing rules to accounts, subscriptions, billing and analytics. Owning embedded support and technical operations kept customer-facing decisions connected to the services behind them, a useful perspective for investment-product integrations.
