Google DevFest Toronto 2025 was an action-packed day filled with inspiration, community, and cutting-edge technology. Held on November 15 at the Sheraton Centre Toronto Hotel, this was my first-ever Google Developers Group DevFest, and it truly lived up to the hype.

From the moment I arrived, the energy was palpable. The schedule was packed with sessions from top Google and industry speakers, hands-on workshops, and numerous opportunities to connect with Toronto’s most passionate developers and tech professionals. One of my favorite parts was diving into the Capture the Flag challenge. Tackling cryptic puzzles alongside fellow problem-solvers pushed me beyond what I thought possible. Crossing the finish line earned me some great swag, including a GDG backpack and NFC keys that I’ll proudly use.

A standout workshop was “Apps Script: Vibe-code a Gmail add-on with Gemini CLI & MCP servers.” In this session, I built a Gmail add-on that uses Vertex AI’s image model to generate unique cat images on demand inside Gmail. Working hands-on with Gemini CLI, MCP servers, gcloud, and Apps Script gave me a practical look at the future of AI-driven cloud apps. I highly recommend this lab to anyone looking to blend code, cloud services, and creativity.

The event perfectly balanced learning, networking, and fun, demonstrating the power of the local developer community and the exciting innovations coming from Google Cloud and AI. For anyone interested in the future of tech, Google DevFest Toronto is a must-attend event to supercharge your skills and connect with like-minded professionals. I’m already looking forward to next year’s experience!
