About
As a Full-Stack Developer with a Bachelor’s in Computer Science, I bridge the gap between complex backend logic and seamless frontend experiences. My expertise lies in the JavaScript/TypeScript ecosystem, specifically React and Node.
Currently, I architect solutions for Legal Ops automation, where I’ve fortified platform security and optimized workflows handling massive financial volumes. Previously, at DD Solutions, I spearheaded the strategic migration of analytics dashboards to React, reducing load times by 40% and automating image annotation workflows that cut manual analysis by 60%.
I am passionate about building modular design systems and optimizing database performance using Prisma and PostgreSQL. I am always looking for challenging projects that require scalable architectures and high-performance code.
