• Proven experience with PHP and Python.
• Desired experience with NodeJS and Express.
• Hands-on experience with AI design tools such as v0.dev, bolt.new, Lovable, or similar platforms.
• Experience with GitHub Spec-kit and Open Spec.
• Experience with workflow automation platforms such as N8N.
• Strong track record of delivering production-grade full-stack applications.
• Solid understanding of backend development, including API design (REST, GraphQL), server-side logic, and database management.
• Experience with platforms like Supabase for rapid backend development and both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases.
• Proficiency with authentication mechanisms (OAuth, JWT) and security best practices.
• Understanding of caching strategies, performance optimization, and scalability patterns.
• Deep understanding of design systems, design tokens, and component-driven development.
• Expert-level proficiency with Figma, including design system management and component libraries.
• Experience with CSS frameworks (e.g. TailwindCSS) and modern styling approaches.
• Strong collaboration and creative problem-solving skills.
• Experience with TypeScript and modern JavaScript/ES6+ features.
• Familiarity with cloud platforms (AWS, Azure, GCP) and deployment workflows.
• A portfolio showcasing full-stack applications you've built, including work with design systems and AI design tools.
• Strong attention to detail and a passion for innovation.
• Ability to work in a fast-paced and dynamic environment.

Responsibilities

• Rapidly transform concepts into interactive prototypes using v0.dev, bolt.new, Lovable, and similar AI design tools.
• Build full-stack applications from prototype to production, with emphasis on frontend excellence and solid backend foundations.
• Ensure all components align with existing design systems (design tokens, color palettes, typography, spacing) and brand guidelines.
• Develop production-ready UI components using modern frameworks (React.js, Vue.js, Nuxt.js) with best practices for accessibility, performance, and responsive design.
• Design and implement RESTful APIs and backend services using platforms like Supabase to support frontend functionality.
• Work with databases (SQL and NoSQL) to manage application data efficiently.
• Implement authentication, caching strategies, and optimize application performance across the stack.
• Collaborate with UX Designers, AI Builders, and Innovation Leads throughout the development lifecycle.
• Utilize GitHub Spec-kit and/or Open Spec to streamline development workflows and maintain specification standards.
• Leverage Figma and design system tooling to maintain component libraries and streamline design-dev handoff.
