Activities in Habitat Hub

What is Habitat Hub?

Habitat Hub was a volunteer software development team formed by engineers who shared an interest in building products outside their full-time jobs.

From June 2023 to November 2025, I participated as a member and contributed to several web application projects while working in an agile and collaborative environment.

How it all started

I have been a member of the "Habitat Hub" since June 2023. It all started when I met @tom-takeru, one of the early members of "Habitat Hub", at a training program. At the time, I was self-taught in React and was looking for a place to share my knowledge. Then I heard that there was a project in development with a similar technology stack and that they were looking for members, so I decided to join.

Major Projects

During my time at Habitat Hub, I contributed to the following projects.

• Daydule

Daydule is a service that automatically creates a schedule based on your registered TODOs and appointments. It is ideal for people who are not good at scheduling and busy people.

• TimeIsMoney

As the name suggests, this application is based on the theme “time is money”. Enter the time you spend studying, etc. and it will be converted into money based on your hourly rate. It also provides examples of products that can be purchased with that time.

• AI-DISCUSSION

AI-DISCUSSION is an experimental web app where multiple AIs freely discuss a topic you give them.
Once you set the theme, AI agents with different personalities and viewpoints start exchanging ideas and having a conversation.
What’s more, you can join the discussion and add your own thoughts, interacting with the AIs directly.

At the end of the conversation, the AI will provide a summary of what was discussed, so you can easily review the key points.
It’s perfect when you want to explore new ideas or get perspectives you might not have thought of yourself.
The app aims to help spark fresh insights and creative thinking through interactions with AI.

Habitat Hub concluded its activities in November 2025.

During the two and a half years I spent with the team, I gained valuable experience in collaborative software development, agile practices, code reviews, and product development.

Key experiences and achievements included:

- Participating in long-term team-based software development

- Working in an agile, distributed development environment

- Contributing to product planning, implementation, and operation

- Collaborating through code reviews and technical discussions

- Delivering multiple web application projects as a team

The lessons learned through these projects continue to influence both my professional work and personal development projects today.
