What I'm looking for

I seek senior frontend roles where I can lead frontend architecture, mentor engineers, build reusable components, and ship scalable data-visualization and fintech products.

I am a senior frontend engineer with deep experience building high-performance, reusable frontend systems for fintech and enterprise applications.

I architected a reusable React + D3 charting framework adopted across multiple internal Goldman Sachs applications, and led migrations to internal query frameworks to improve stability and maintainability.

At startups I owned frontend architecture and led small engineering pods, delivering income and employment verification products, micro‑frontends, and cross-platform SDK integrations.

I emphasize modular, maintainable code, developer experience (Storybook, CI/CD), and mentoring teams to ship production-quality frontends quickly.
