From Voice to Action: Building an AI Assistant with Python and Google Workspace
Jumping between Gmail, Calendar, Drive, and Jira tabs for repetitive tasks is exhausting. That's why we built Attento, an assistant that lets you execute real actions in Google Workspace using natural language. In this talk we build Attento, an end-to-end voice assistant that turns natural language into real actions across Google Workspace. We'll cover architecture with FastAPI, OAuth 2.0 authentication with PKCE, function calling with Gemini, streaming with NDJSON, best practices with uv and Pydantic Settings, and the path from demo to production with Postgres and automated morning briefings.

Python in the Browser: Powered by WebAssembly
What if the browser could run Python as a first-class language? In this talk, I'll show how PyScript makes it possible to execute real Python directly in the browser, powered by WebAssembly. Through a series of exciting, live examples, you'll see Python manipulating the DOM, calling browser APIs, and building interactive experiences, all without a traditional JavaScript codebase. I will also show a couple of examples of how you can embed both JavaScript and Python on PyScript to make even more exciting tools. I will also discuss what WebAssembly is, why it exists, and how it enables languages like Python to run safely and efficiently on the web platform. Finally, I'll discuss when tools like PyScript make sense, and compare it with similar tools. Whether you're a Python developer curious about the frontend, an engineer interested in WebAssembly, or simply someone who enjoys seeing the boundaries of Python pushed, this talk will change how you think about what can run in a browser.
Real-Time Voice Systems: Design and Architecture in 5 Levels
Voice systems have advanced rapidly in recent years, but most implementations still stop at demos: simple combinations of Speech-to-Text, language models, and Text-to-Speech that work in controlled environments but fail when facing real-world conditions. This talk proposes a different approach: understanding voice systems as an architecture that evolves through maturity levels, from basic prototypes to real-time production-ready systems. Through a 5-level framework, we'll walk the full path of a Conversational AI system: from integrating basic components, through orchestration challenges (streaming, latency, turn-taking), to less obvious but critical problems like audio quality, robustness, and user experience, reaching real-time architectures with technologies like LiveKit, and finally exploring where the future is headed with end-to-end systems and multimodal agents. The talk is based on real experience building voice systems in production and focuses on engineering decisions more than specific tools. Attendees will leave with a clear understanding of how to design modern voice systems with Python, what problems to anticipate, and how to structure their own architectures to build world-class conversational experiences.
Stop mocking, start containerizing
“Write tests. Not too many. Mostly integration.” Kent C. Dods While unit tests have their place, integration tests validate how your systems behave under real-world conditions. Yet too often, developers fall back on mocks that simulate dependencies rather than testing with the actual services their code interacts with. In this workshop, we’ll explore a better approach: Testcontainers is a powerful Python library that enables you to run real Docker containers as part of your test suite. Whether you're testing against PostgreSQL, Redis, or HTTP APIs, you’ll learn how to spin up disposable, isolated environments that bring realism and confidence to your testing practice. Whether you're testing microservices, monolithic backends, or data pipelines, this workshop will show you how to build tests that don’t just pass but prove your system works. Bring your laptop and a running Docker engine, we’re going to get our hands dirty!
