About Benjamin Cohen
As a Senior Software Engineer at SoFi, I bring over seven years of experience in software development, specializing in frontend technologies. My expertise includes TS, React, MUI, Next, Tanstack, and Optimizely, with a strong focus on creating efficient and reliable interfaces using React and its ecosystem. At SoFi, I contribute to building production-level systems while collaborating with designers and product managers to deliver pixel-perfect user experiences. I worked on the student loan refinance funnel and drove A/B testing leading to a $9 million increase in MRR.
