Build Your Own AI Personal Assistant — A Hands-On Workshop with an OpenAI Codex Ambassador

What if the next AI tool you used was one you built yourself? ✨

​An assistant that remembers your preferences, checks your calendar, and helps you organise your day—from a conversation on WhatsApp.

​That’s what I’ve been building with Pippa, my personal AI scheduling assistant. On Saturday, 24 October, I’m opening up the project and teaching you how to start building your own.

​This four-hour paid workshop brings together a guided build, live demonstrations, and the practical lessons behind Pippa: connecting an agent to real tools, giving it memory, and deciding when it should act or ask for confirmation.

​What we’ll explore

​OpenAI Agents SDK: instructions, tools, agent execution, and conversation sessions.

​Agents API: a live demonstration and discussion of how it fits into an assistant’s architecture.

​Google Calendar and Gmail: connecting an assistant to useful personal context.

​WhatsApp and voice notes: making your assistant accessible through everyday conversations.

​Memory and permissions: remembering preferences, connecting accounts with OAuth, and protecting credentials.

​Python, FastAPI, SQLite, and Railway: the application stack behind Pippa, from local development to deployment.

​Reliability: handling failures, checking tool results, and keeping you in control of consequential actions.

​The goal: build a small working assistant during the workshop, understand the architecture behind Pippa, and leave with a clear path to extend your own.

​We’ll focus the hands-on build on the core agent and tools, with demonstrations of the wider integrations.

​Who is this for?

​Developers, technical founders, and curious builders who want to move from chatting with AI to creating useful assistants. Basic Python familiarity will help. Bring your laptop and a task you’d love an assistant to handle.

​📅 Saturday, 24 October 2026 🕘 9:00am–1:00pm · Singapore time 📍 [Venue released to confirmed participants] 🎟️ Paid workshop · $100 per pax
