Join the Exciting AI Hackathon Powered by GEECHS JOB for IT Engineers

AI Hackathon Powered by GEECHS JOB: An Invitation for IT Engineers

On October 26, 2025, GEECHS Inc., based in Shibuya, Tokyo, is hosting an engaging event aimed at IT engineers—the AI Hackathon Powered by GEECHS JOB. This hackathon is not only a platform for skill showcase but also a community-building opportunity for IT professionals eager to explore the capabilities of generative AI.

Background of the Event

GEECHS Inc. regularly organizes events tailored for IT engineers and recruiters. This time, the focus is on a hackathon that aims to provide IT freelancers a stage to collaborate and innovate using cutting-edge technologies related to generative AI.

As many IT freelancers operate without being tied to a single company, they must continually seek new projects and enhance their market value. Understanding the trends in technology and services is crucial, and the interest in generative AI has surged. Participants can engage in knowledge-sharing and practical applications of these technologies, reinforcing the reason for hosting this event.

Whether you wish to share your development knowledge about generative AI, collaborate with fellow engineers to think innovatively, or simply want a chance to participate in a hackathon, we encourage you to join us!
