About

With a background in quality systems and a passion for building intelligent web solutions, I’ve dedicated the last few years to mastering full-stack development and contributing to real-world AI training pipelines. I thrive in remote environments, collaborating with distributed teams across time zones to solve practical problems with scalable, data-driven solutions. I’m seeking remote opportunities where I can apply my skills in React, Node.js, AI data workflows (NLP, RLHF), and multilingual data processing to build products that make a meaningful impact. I value async communication, clean architecture, and continuous learning.
