What I'm looking for

I’m looking for a team where I can build high-performance full-stack products—using React, Node, and Python—and also tackle low-latency systems. I want ownership, clean CI/CD, and room to grow into tougher performance and security challenges.

I’m a Full Stack Developer focused on building fast, reliable web applications—especially low-latency trading dashboards. At Gray Marrow, I developed React.js dashboards on Linux and improved interaction speeds by 35% while boosting responsiveness during market spikes by 25%.

I also translate tick-level data into actionable visuals by using Python (Pandas and NumPy) to aggregate market data into OHLCV candlesticks via time-based resampling (1s, 1m, 5m). On the backend side, I optimized low-latency trading system components using C++ on Linux, reducing processing latency by up to 35% through efficient multi-threading and memory management.

Previously at Solytics Partners, I revamped legacy code with React, Redux, and React Table for a 40% performance boost and reduced page load times by 2 seconds. I’ve built full-stack experiences with React.js and Node.js (50% monthly active users growth) and architected RESTful APIs using Django to reduce server response time by 40%. I enjoy hands-on engineering, debugging, and shipping user-focused improvements.
