AI agents that hold real conversations, on the phone and on the web.

• Agents that listen, reply and know when to stop talking
• Voices that sound human, in more than one language
• Tools to build, test and understand agents
• Giving agents knowledge and memory

People usually reply within about a fifth of a second. An agent has to think inside that gap.

The parts nobody sees: services, data, and what happens when a lot of it arrives at once.

• APIs and services
• Data models, caching and background jobs
• Real-time audio and events
• Monitoring that spots trouble first

The best backend work is invisible. That’s rather the point.

Interfaces that feel fast and obvious, on the web and on phones.

• Web apps and dashboards
• Mobile apps
• Design systems and shared components
• Turning slow screens into fast ones

Where I started, as an intern. I still notice every janky scroll.

Working out what to build, and for whom, before writing the code.

• User research and testing
• Flows, wireframes and prototypes
• Design docs that settle debates early

I was a designer before I was an engineer. It never wore off.
