  • Build scalable, user-friendly front-end applications using React.js.
  • Develop robust backend services using Node.js (Express, Nest, or an equivalent framework).
  • Integrate with AI services such as OpenAI, Claude, or Gemini for advanced product capabilities.
  • Deploy applications using GCP and manage infrastructure (CI/CD, hosting, environment setup).
  • Work with both SQL and NoSQL databases, including PostgreSQL and Firestore.
  • Collaborate with internal stakeholders to ensure best practices in full-stack architecture and deployment.
Must Haves
  • React.js – Proven experience building interactive front-end applications.
  • Node.js – Experience with frameworks like Express or Nest.js and ability to justify technical choices.
  • AI API Integration – Familiarity with implementing external LLM APIs (e.g., OpenAI, Claude, Gemini).
  • SQL & NoSQL – Strong experience with PostgreSQL and document-based databases (e.g., Firestore).
  • GCP – Hands-on experience deploying/managing applications in Google Cloud Platform.
  • Firebase / Firestore – Comfortable integrating Firebase services.
  • DevOps Ownership – Capable of handling deployments, CI/CD pipelines, and cloud hosting.
Nice To Have
  • TypeScript – Bonus if you've used it in production.
  • Python or Elixir – Helpful for understanding and transitioning the current codebase.
