• React Query (TanStack Query) for server state management
• Experience with modern styling approaches like Tailwind CSS

• Familiarity with authentication systems like Clerk
• Experience with Stripe or payment integrations
• Experience with AI integrations (e.g., OpenAI, Vercel AI SDK)
• Exposure to Docker and cloud services like AWS S3
• Experience working on SEO optimization and performance improvements
• Prior experience working closely with founders or startup teams

What Success Looks Like

• Owning and shipping features end-to-end with minimal hand-holding
• Writing clean, scalable, and well-documented code that the team can build on
• Proactively identifying performance bottlenecks and resolving them before they become problems
• Contributing meaningfully to architectural and product decisions alongside the founding team

What‘s in It for You
