What I'm looking for

I’m looking for a team where I can build scalable, low-latency UI and real-time workflows—while pushing AI-driven engineering, workflow automation, and developer productivity to ship faster without sacrificing quality.

I’m a Software Engineer with experience building high-performance frontend and full-stack applications across fintech, trading, and web platforms. I specialize in React, TypeScript, and real-time systems, with a strong focus on scalable UI architecture and low-latency, data-driven features.

At JPMorganChase, I’ve built interactive React + TypeScript tools for traders to inspect ETF baskets, monitor live pricing and risk, validate inputs, and submit workflows into pricing & valuation engines. I’ve also led AI-driven engineering initiatives—using AI agents, reusable skills, and workflow automation—to accelerate delivery, while partnering with backend engineers to integrate low-latency market data and automated testing to keep quality high.
