What I'm looking for

I’m looking for a team where I can modernize and ship scalable React/Node products, collaborate closely with stakeholders, and own features end to end—while using emerging frontend and infrastructure practices to improve performance, reliability, and developer productivity.

I’m a Senior Full Stack JavaScript Developer with more than six years of experience delivering complex, scalable digital products using React, Next.js, Node.js, and Express. I work independently from concept to deployment, translating business needs into technical solutions while keeping code quality and performance high under tight deadlines.

Most recently, I led codebase modernization, built robust backend APIs, and improved UX through interactive frontend experiences—while serving as the primary technical liaison to stakeholders. I’ve also migrated legacy builds to Vite (reducing build times by 40%), delivered data visualizations using Chart.js, and supported team productivity through training and cross-team stand-ups.
