WebMCP at Scale with Susanna Wong (Typeform, Google Developer Expert) | Browser AI, Offline Models, Agents

What happens to frontend engineering when software stops being deterministic?

In this episode of Señors at Scale, Dan Neciu sits down with Susanna Wong, Staff Software Engineer at Typeform and Google Developer Expert in Web Technologies since 2020. Susanna's path is anything but typical: she studied engineering in the US, spent close to seven years as an architect and computational designer at firms like Arup, then pivoted back into software, building Kedro and Kedro-Viz at QuantumBlack before moving into AI features at V7 and now Typeform.

Susanna breaks down the shift from training your own ML models to building on top of LLMs, what Web AI and offline browser models really offer, and the cross-browser hurdles still blocking local-first AI. She also takes us inside Typeform's multi-agent system, how the team thinks about evals for non-deterministic features, and why WebMCP could change how all of us build websites.

Key Topics:

- From architecture and computational design to frontend AI

- Building Kedro and Kedro-Viz at QuantumBlack

- Why training your own models gave way to the LLM baseline

- Web AI, offline models, and on-device inference

- The cross-browser problem with local-first AI

- Typeform's multi-agent system: LangChain, A2A, MCP tools

- Evals as unit tests for non-deterministic AI features

- Offline vs online evals and tracking drift in production

- WebMCP: bringing the web to agents
