About the project We’re building GoodCare OS — an operating system for home care and pediatric home health agencies. Already have a polished React demo (~25,000 lines, three apps: admin web, caregiver mobile, nurse mobile) running on git hub (will share link when you apply). Our founder runs three real agencies in TN and TX, so the platform has built-in customer #1. We need a senior engineer to take this from demo to production SaaS. Sprint 1 (2 weeks) is the foundation: set up real infrastructure, migrate mocked demo data to a real Postgres database, wire up auth, get the first customer org logging in. Tech stack React 18 + Vite · Node.js · Supabase (Postgres + Auth) · Render · Netlify · Doppler · Sentry · PostHog. Familiarity with Twilio, Stripe, and React Native a plus for follow-on sprints. Must-haves • 5+ years shipping production web apps end-to-end • Strong React + TypeScript • Postgres fluency, especially row-level security • Worked at an early-stage startup as the only or one of few engineers • US-based or full overlap with US Central Time • HIPAA experience strongly preferred Nice-to-haves • Healthcare SaaS / EVV / Medicaid billing experience • Multi-tenant SaaS architecture experience • Shipped a React Native / Expo app to stores How to apply Please include: 1. Link to a production app you shipped (your role + what you built) 2. One paragraph on the trickiest production bug you ever fixed 3. Your hourly rate and availability over the next 2 weeks No agencies, no resellers, no generic proposals. I’ll respond within 48 hours to anyone whose application addresses the three points above.

Are you a developer who actually enjoys talking to people, or a tech-adjacent professional who wants to leverage your software background for high-paying outbound roles? We are building an engineering-focused platform and need a Native American English speaker to handle technical discovery calls and schedule product demos with CTOs, VREs, and Lead Architects. Instead of reading a robotic script, you will be having peer-to-peer technical conversations to qualify leads. We are specifically looking for someone with prior development experience (React, Node.js, Python, or similar stacks). You won't be writing code in this role, but you must speak the language. Because you understand architecture bottlenecks, API integrations, and developer pain points, you can easily navigate technical gatekeepers and hold meaningful conversations with senior engineering leadership. This is a fully remote, part-time position with highly flexible hours, but calls must be made during standard U.S. business hours (EST/PST). You will need a quiet home office, a solid internet connection, and a professional headset. If you want to step away from the IDE for a few hours a day and use your dev background to drive outbound growth, apply with a quick overview of your tech stack and a brief Loom introduction.
