Social Media Posting Automation

I need a small, reliable piece of software that lets me create, schedule, and publish social-media posts to Facebook, Instagram, and Twitter from a single dashboard. The focus is on functionality rather than flashy design: connect to each platform’s API, give me a clean form where I can write or paste the post copy, attach an image or video, set a date and time, and hit “schedule.”

I am open on the tech stack—Python or Node.js on the back end and any lightweight front-end framework you favour—so long as it remains easy for me to deploy on a standard VPS. Please use each network’s official API (Graph API for Facebook, Instagram Basic Display or Graph endpoints for Instagram, and the current Twitter API).

Deliverables should include:
• Source code with concise setup instructions
• A short README explaining how the API keys need to be stored securely
• A quick demo video or live link showing the tool in action

Once everything is tested and running, hand over the repo and any credentials I’ll need to maintain it on my own server.
