Hacktoberfest Hack Day Portland x Portland AI Devs
About
Join us for a Hacktoberfest community event focused on learning, collaboration, and open-source contribution. Whether you’re new to open source or an experienced contributor, this is an opportunity to connect with fellow developers, explore real-world projects, and build together.
Throughout the event, participants will have the opportunity to:
Learn how to get started with open source and make meaningful contributions
Discover and contribute to projects that align with their interests
Collaborate with fellow developers and community members
Work on pull requests, issues, and other open-source contributions
Share knowledge, ideas, and experiences with the community
Meet new people and grow their developer network
The event is designed to be welcoming to developers of all experience levels. You don’t need to be an open-source expert to participate—just bring your curiosity, willingness to learn, and a desire to build something together.
Whether you join us in person, online, or through a combination of both, come ready to learn, collaborate, contribute, and connect.
Let’s celebrate open source and make Hacktoberfest a month of meaningful contributions and community-driven learning!
