Senior Full Stack Engineer (React, Next.js, React Native, Node.js) for Early-Stage Startup

Hi, I'm looking for an experienced full-stack engineer to join me on a long-term product. We're building a modern platform with web, mobile, and an admin dashboard. The project is still in its early stages, so I’m looking for someone who enjoys working closely with founders, making technical decisions, and building a solid foundation from the beginning. Our current technology stack includes: * React * Next.js * React Native * Node.js / NestJS * PostgreSQL If you've built SaaS products or other complex business applications, I’d love to hear from you. I’m not looking for someone who simply completes assigned tasks. I’m looking for someone who can think through problems, suggest better approaches when appropriate, and take ownership of their work. Please include the following with your proposal: * Your latest resume (PDF) * Links to 2–4 projects that are most relevant * GitHub profile (if available) * A brief explanation of your role in those projects I’d also appreciate it if you could answer the following: 1. Which project you’ve worked on is most similar to this one, and what exactly was your role? 2. Have you worked directly with startup founders? If yes, tell me a little about your experience. 3. If you were starting this project today, how would you structure the architecture at a high level? I'm far more interested in how you think, communicate, and solve problems than in a long list of technologies. Please keep your proposal concise and genuine. I’m more interested in your real experience than a polished response. Looking forward to hearing from you. Thanks
