  • Frontend Development : Craft highly responsive and accessible UIs using React, Redux Toolkit, Tailwind CSS, and component-driven architecture.
  • AI & Real-Time Features : Integrate AI-powered features such as LLM-based text processing, basic NLP functionalities, and real-time updates using WebSockets or similar protocols.
  • DevOps & Cloud Deployment : Set up and manage deployments using AWS (especially EC2), Vercel, or GCP. Implement CI / CD pipelines, monitoring, and alerts.

  • AI-Curious & Capable : You have hands-on exposure to WebSockets, LLMs, or NLP whether through projects or experimentation.
  • Security-Conscious : You take endpoint protection, RBAC, token management, and data security seriously.
  • High Ownership : You don’t wait to be told rather you see a gap, and you fill it.
  • Strong Communicator : You write and speak with clarity, and you’re collaborative in remote-first teams.

You might be integrating an AI-powered chat module, optimizing database queries, deploying to AWS EC2, or refining RBAC-based access flows. You'll also join calls with the founder to prioritize next steps and share architectural input. The work is high-impact, hands-on, and foundational.
