• AI/ML Integration: Experience deploying or integrating LLMs and AI‑driven features into consumer‑facing products.
• Performance Languages: Proficiency with Rust and Tauri for high‑performance desktop or system‑level applications.
• Startup Growth: Prior experience scaling a product from “early‑stage” to “mass‑market” in a high‑growth environment.

• Innovative: We bring AI to the masses with proactive technology that acts as the ultimate AI assistant. Built on our proprietary, patented technology, Read AI takes notes, surfaces information, facilitates collaboration, and learns you, making individuals and teams more effective.
