I’m a full-stack engineer with 4+ years building production React/TypeScript applications, shipping features that move real workflows forward. I love turning messy inputs into deterministic, auditable systems—especially when performance and reliability matter.

At YieldStream, I reduced document processing from 60s to under 2s by designing a 4-tier extraction cascade (pdfplumber, PyMuPDF, Tesseract, LlamaParse). I also built a 3-layer scoring model that replaced gut-feel routing with deterministic, auditable lender recommendations, backed by a scalable Python/FastAPI microservice and AWS Lambda deployment.

Previously at GiveWP, I shipped 253 pull requests across core plugin and addons for two major releases (3.0 and 4.0). I co-built the visual donation form builder (React 18, TypeScript, Gutenberg), helped lead the v2-to-v3 migration across multiple mailing integrations using a non-destructive abstraction, and introduced campaign-based fundraising in the 4.0 release.

I care about quality end-to-end: I led accessibility audit remediation (ARIA labels, keyboard focus, semantic HTML, heading hierarchy, and color contrast standards) and focused on maintainable architecture through modular admin UI refactors. Earlier in my career, I managed full-cycle underwriting deal flow—an experience that directly shaped the thesis behind YieldStream.
