• AI Tooling: Hands-on experience with OpenAI API, LangChain, or automation frameworks (e.g., Zapier, Make, Vercel Functions).
• Database & Infra: Familiar with Firebase, Supabase, PostgreSQL, and cloud deployment (Vercel, AWS, or GCP).
• Version Control: Proficient with Git, GitHub, and CI/CD pipelines.
• AI-Native Mindset: Uses GPT-5, Copilot, or Cursor IDE to accelerate coding and problem-solving.
