Bloomberg-inspired market sentiment tracker built with Claude Code

I had been wanting to play around in a project with dense user interfaces and Bloomberg terminal aesthetics and, so an investment dashboard seemed like a good fit.

It aggregates market indicators that have been known to generate contrarian buy/sell signals. CNN Fear & Greed, Bank of America SSI, AAII Investor Sentiment Survey among others.

A few technical details:

* vibe coded ~70% of it — the parts that not were either UI polish that was faster to do directly or points of the data scraping pipeline where Claude got stuck

* architecture: vanilla JS frontend + Python/Flask backend + background jobs that run an AI data extraction pipeline (Perplexity Sonar / Exa for search + GPT-5)

* runs on render.com as web service + two cron jobs that run the data update process and send daily email notifications

At some point I did try Codex for a few PRs that were never merged and I re-did instead with Claude.
