Nicholas Genco

Senior Full Stack Software Engineer

New York City & Long Island, NY

Summary

I build scalable, high-performance applications.

My focus is on modernizing legacy systems into maintainable, reusable ecosystems using the React/Preact stack, TypeScript, and RESTful services. I specialize in design system engineering, performance optimization, and creating component libraries that accelerate development at scale.

At Oracle, I architected reusable Web Component libraries that improved development velocity and created uniform patterns within the organization. I've led the adoption of TypeScript across legacy codebases and helped evolve a more modern engineering workflow for internal teams.
