• 2 to 3+ years of professional full stack engineering experience
• Strong hands-on experience with React, Next.js, and React Native
• Backend experience with Python and/or Golang in production
• Solid understanding of PostgreSQL, APIs, and system design
• Strong fundamentals in HTML, CSS, TypeScript, and modern frontend patterns
• Ability to work independently and take ownership in a startup environment

• Familiarity with cloud platforms like AWS or GCP
