Hello, my name is
Seth Elliott.
A Software Engineer specializing in web & app development.
Software Engineer at Sunrun. I build production web apps with Next.js and SvelteKit — from Salesforce-integrated internal tools to full-stack products like Route Zero.

A bit about me
Engineering robust, intuitive digital experiences with a blend of frontend expertise and backend know-how.
🎓 A.Sc. + B.Sc.in Web Design & Development from Utah Valley University.
My Current Tech Stack
Full-stack builder
I move fluidly between frontend and backend — building component systems in Svelte and React, and the APIs, databases, and integrations that power them. That range shows up in production work like a Salesforce-integrated internal tool at Sunrun and Route Zero, a full-stack app backed by Postgres and a live third-party catalog API.
Design-minded
Clean architecture and clean design come from the same instinct: build systems that stay maintainable as they grow. I structure component libraries, state, and interactions with reuse and accessibility in mind from the start, not bolted on afterward.
Ships with teams
Direct, transparent communication is what turns a plan into a shipped product. At Sunrun, that meant owning requirements gathering and aligning engineering and design stakeholders end-to-end on a team-wide internal tool.
