DogeTheBot
DogeTheBot is a Node.js automation system built on whatsapp-web.js and Puppeteer. It handles group administration, media workflows, text-to-speech, meme/image utilities, and command routing, while also exposing a lightweight code-execution playground.

Contributions
What was built
Built command routing, authorization, group controls, and media workflows.
Added an in-chat coding playground for C, Python, and Node.js.
Deployed the runtime with Puppeteer and FFmpeg-friendly infrastructure constraints in mind.
Technical decisions
How the implementation was shaped
whatsapp-web.js provided direct automation without relying on the official business API.
Feature modules separated command handling from media/runtime concerns.
Puppeteer and FFmpeg support made the bot viable for richer command categories.
Challenges
Operational and engineering constraints
Keeping WhatsApp sessions stable across restarts and constrained hosting environments.
Balancing admin features with authorization and abuse controls.
Coordinating multiple runtime-heavy features in a chat-driven interface.
Outcomes
Why the project matters
20+ user-facing commands across admin, media, and utility workflows.
Event-driven command routing across group admin, media, and code execution features.
