- Own frontend architecture for AI-first products, including reusable components and scalable UI patterns
- Integrate frontend applications with AI backends (LLMs, agent orchestration layers, RAG pipelines)
- Translate complex AI behaviors into clear, usable user experiences
- Optimize frontend performance, responsiveness, and reliability for real-time AI interactions
