This is a submission for the MLH x DEV Writing Challenge
What I Built
Learning Data Structures, Algorithms, and full-stack development can feel daunting when you're navigating complex documentation alone. As the maintainer of CodeHarborHub, an open-source platform dedicated to empowering developers through structured learning paths. I wanted to create an interactive tool to make self-paced technical education truly engaging.
I built AI Buddies, an open-source AI learning partner integrated within the CodeHarborHub ecosystem. Instead of acting as a typical chatbot that dumps ready-made answers, AI Buddies provides step-by-step guidance, breaks down algorithm concepts with real-time visualizers, and acts as a patient partner for learners solving coding challenges in an interactive sandbox.
Key Learnings:
- Designing non-intrusive AI agents that guide learning rather than completing tasks for the user.
- Structuring lightweight MDX and React execution environments for seamless browser rendering.
- Balancing client-side interactivity with open-weight model architectures.
Demo
- Live Platform: AI Buddies
- Main Ecosystem: CodeHarborHub
- Interactive Roadmaps: Explore live data structure visualizers and agentic learning modules directly in the browser.

ai-buddies
Learn AI through hands-on projects, interactive learning paths, and community-driven content. Explore machine learning, deep learning, NLP, computer vision, and more. Stay updated with cutting-edge trends and build real-world AI skills.
Website
This website is built using Docusaurus, a modern static website generator.
Installation
npm install
Local Development
npm start
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
Build
npm run build
This command generates static content into the build directory and can be served using any static contents hosting service.
Deployment
Using SSH:
$ USE_SSH=true npm run deploy
Not using SSH:
$ GIT_USER=<Your GitHub username> npm run deploy
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.

Partner Technologies
To keep the platform fast, responsive, and open for global contributors, I utilized several core technologies and developer platforms:
- GitHub & GitHub Actions: Used for hosting our repositories, managing open-source contributor pull requests, and orchestrating CI/CD pipelines to build and deploy docs and interactive components automatically.
- Open AI & Agent Harnesses: Integrated open-weight model routing and agent framework concepts (such as LangChain and Hugging Face open weights), enabling learners to leverage model flexibility without vendor lock-in.
- Frontend Stack: Built using React, TypeScript, Tailwind CSS, and Docusaurus for fast, modern documentation layouts with interactive live code previews and KaTeX notation support.
Implementing these tools allowed us to maintain zero-cost inference paths for students while giving them full control over model customization and data privacy.
Hackathon Experience
Participating in hackathons as part of the MLH community is always an invigorating experience. The collaborative atmosphere, late-night debugging sessions, and feedback loops with fellow hackers inspired many of the features now powering AI Buddies.
What I’ll remember most is sharing our live visualizers with student developers during community review rounds. Seeing learners instantly grasp a complex tree traversal or dynamic programming concept through an interactive agent session reminded me why open-source community building matters so much.
