Cooper Featherstone

Full-Stack Developer building production-ready web applications

I build real-world applications with authentication, APIs, and modern frameworks like React and Next.js — focused on usability, performance, and business impact.

01 — Cooper Featherstone LLC

Founder & Full-Stack Developer

Early-stage product engineer who ships production work.

  • Built and launched production web apps and SaaS-style products (React, Next.js, APIs)
  • Client work end-to-end: UI/UX, backend integration, deploy
  • Auth, dynamic data, responsive UI
  • Full product lifecycle, concept to production

02 — Practice

Production signals, not vibes.

Full-stack apps deployed

Public deploys on GitHub Pages and Vercel, including Funnel Maker, Daily Methods Hub, InvoiceForge, and more.

Authentication + database

Supabase auth and Postgres-backed product flows in Funnel Maker and Daily Methods Hub. Access-gated dashboard path in IG Command Center.

API-driven products

App Router API routes for funnels, billing, AI generation, and CRUD — visible in the public repositories.

03 — Selected work

Products, not homework.

Each build below is real source or a live deploy. Proof is limited to what the repo or live site actually shows.

04 — About

I ship usable software.

I focus on building real-world applications that solve practical problems. Most of my work centers around full-stack development using React and modern backend tools, with an emphasis on performance, usability, and clean design.

Internships at JB Hunt and Walmart sit behind the work. The public repos are the proof: auth, APIs, dashboards, and deployed apps.
