GDG Markham October Hackathon 2026

Build AI solutions for challenges that matter to Markham Join developers, designers, students, product thinkers and community members for the first GDG Markham Community AI Hackathon. Markham residents and youth will open the event with one-minute reverse pitches describing local issues, concerns and opportunities. Developers will choose a challenge, form a multidisciplinary team and spend the day building a working prototype with support from technical and product mentors. You do not need to arrive with a team or project idea. We will facilitate team formation after the community pitches. We are looking for technology co-builders We welcome participants with experience or interest in: Artificial intelligence and machine learning Web and mobile development Cloud architecture and backend development Android or Flutter development Firebase Google Cloud Gemini and generative AI User experience and product design Data analysis Technical presentation and product demonstrations Professional developers, students, independent builders and first-time hackathon participants are welcome. You do not need to be an expert in every technology. Teams need people with complementary skills who are willing to learn, collaborate and build within a limited timeframe. What you will build Each team will select a challenge presented by a Markham resident, youth speaker or community representative. Possible areas include: Accessibility and inclusion Education and youth opportunities Community services Small business support Sustainability Transportation and mobility Multilingual access to information Civic participation Neighbourhood connections Teams will define the problem, identify the intended users and create a functional prototype that can be demonstrated by the end of the event. Projects are not expected to be production-ready. A focused prototype that clearly demonstrates the proposed solution is sufficient. Technologies Teams may use: Gemini and Google AI Studio Vertex AI Firebase Cloud Firestore Firebase Authentication Firebase Hosting or App Hosting Flutter Android Google Cloud Cloud Run Google Maps Platform Other complementary development and design tools Participants may use technologies outside the Google ecosystem when they support the project. Meaningful use of a Google technology is required only for the Best Use of Google Technology award.
