About
I am a senior full-stack engineer with 5+ years building SaaS and consumer applications using Next.js, NestJS, React, Node, and AWS. I focus on shipping production-ready features, improving performance, and mentoring engineering teams.
At Kosmic I led frontend development for an AI video-editing platform, implemented complex features with TypeScript and React, and ensured cross-browser session stability and payment integrations.
Previously I managed teams of 5+ developers at Devsinc, redesigned architectures, reduced sign-up drop-offs dramatically, and achieved high client satisfaction through careful library evaluation, caching, and refactoring.
I publish utility packages (npm), write tests with Jest and Cypress, and deploy on AWS and Docker; I seek roles where I can drive architecture, mentor engineers, and deliver impactful, user-centered products.
