Required:
Proficiency in full-stack development with TypeScript/JavaScript and Python
Backend experience with Node.js and REST API design/consumption
Frontend experience with React for building scalable UIs
Experience with PostgreSQL and Supabase for data modeling and storage
Hands-on experience integrating AI/ML features via providers like OpenAI or Claude
Ability to thrive in a founding-stage startup environment — owning features and shipping rapidly
Strong communication and cross-functional collaboration skills
