Senior Full Stack Engineer / Technical Advisor for AI Powered Wine Startup

I'm looking for an experienced senior full stack engineer who enjoys working with founders and acting as a technical thought partner, not just completing development tickets. A little about me: I'm a former Google Product Manager with a strong technical background. I've been building my startup, Sommplicity, myself using Next.js, Supabase, Vercel, Stripe, GitHub, and AI coding tools like Claude Code and Codex. The application has progressed much further than I expected, and I continue to build most features independently. Where I need help is with the deeper engineering challenges. I'm looking for someone who can review architecture, solve difficult bugs, recommend best practices, identify technical debt before it becomes a problem, and help ensure the product is production ready. This is not a project where I hand off a list of tasks. I'm looking for someone I can collaborate with over time as a trusted technical advisor. Current areas where I'd like support include: Architecture reviews and technical guidance Debugging complex issues Production readiness and launch planning Code reviews and best practices Performance and scalability improvements Security and authentication reviews Database and API design GitHub workflow and deployment guidance Technical planning and prioritization Looking ahead, one of my biggest priorities is expanding Sommplicity into a mobile application. Experience with React Native and Expo is a significant plus because I'd like to make architectural decisions today that support both web and mobile. Our current stack includes: Next.js React TypeScript Supabase PostgreSQL Vercel Stripe GitHub AI assisted development using Claude Code and Codex The ideal person is someone who: Has shipped multiple production web applications Has experience with modern React and Next.js Understands scalable software architecture Is comfortable reviewing and improving AI generated code Can explain technical concepts clearly Enjoys mentoring and collaborating with technical founders Has React Native or Expo experience (preferred) This will likely begin as 5 to 10 hours per week with the opportunity for a longer term relationship if we're a good fit. When you apply, I'd love to hear: A little about your background and the types of products you've built. Whether you've worked with AI assisted development workflows. Your experience with React Native or Expo. Why this type of advisory role interests you. More than anything, I'm looking for someone whose judgment I can trust. I'd much rather work with an experienced engineer who helps me make better technical decisions than someone who simply writes code.
