> Front-End Software Engineer [React / Next.js • React Native • Svelte / SvelteKit • TypeScript]

Location: New Rochelle, New York, United States
Profile: https://flows.cv/tremayne

I am a NY-based Front-End Software Engineer with a background in Applied Mathematics and Computer Science.  I have been coding professionally for over 7 years and for fun for much longer—dating back to the days of Myspace HTML profile templates.

I got my start with AdGreetz, a personalized marketing startup, where I collaborated directly with leadership to revamp their company website and content management system and develop custom email campaigns. From there, I joined Fetch Rewards, where I worked across multiple teams on products ranging from data management dashboards and backend services to mobile applications and Svelte-based micro frontends. I also contributed to shared libraries, CI/CD pipelines, developer documentation, and supported the hiring process by reviewing take-home tests, conducting phone screens, and onboarding new developers.

What excites me most in this field is exploring new technologies and tools to discover better, more creative ways to solve user problems and elevate UI/UX. I’m currently seeking my next big opportunity with a diverse, inclusive team that prioritizes user experience above all else and encourages developers to experiment with new approaches to building great products.
