What I'm looking for

I’m looking to own frontend features end-to-end—building fast, reliable React/TypeScript and Next.js (SSR) user experiences that integrate cleanly with Node.js/NestJS backends, with room to influence architecture, performance, and product outcomes.

I’m a Senior Frontend Engineer with 7+ years building production web applications across FinTech, Healthcare, and Web3. I’m deep in React, TypeScript, and Next.js (SSR), focusing on component architecture, performance, and complex client-facing workflows.

I like owning features end-to-end: integrating cleanly with Node.js/NestJS backends and designing UI that matches real API behavior instead of “throwing work over the wall.” In past roles, I built and shipped user-critical experiences like real-time session interfaces, analytics surfaces, and reliability-focused client workflows.

Most recently, I’ve been building the React/TypeScript frontend for a live video-streaming product with real-time UI and recording controls, backed by a Node.js/NestJS service. Previously, I developed React interfaces for an AI-assisted brokerage MVP and built React/TypeScript NFT marketplace and wallet-flow experiences alongside NestJS + AWS backends.
