You can read about a trader’s job for a year and still have no judgment. Books and LLMs give you the vocabulary, but consequence gives you instinct and confidence to act. I think what’s missing is a flight simulator for judgment — something that takes you through the day-to-day: the Slack messages with the trader’s boss and peers, the pressures, the incentives, and the regrets.

To demonstrate that, I vibe coded a few standalone HTMLs that take you through the day-to-day of different roles, such as a Trader, a Jr. Software Engineer, a Product Manager, and an ML Researcher.

Each day starts with a briefing. There is a Slack channel showing communication with the boss and peers, and different artifacts one needs to use and a clock, emphasizing the time pressures.

And of course, a bit of a disclaimer: No guarantee these accurately capture the day-to-day experience. They can obviously be further enhanced by feedback from people in those actual roles through interviews and role plays. The intent is to share the concept.

You can find the GitHub repo here. No installs needed — just open index.html.

I vibe coded sesh because of that.
It’s available on my GitHub (github.com/m-gharibi/sesh), feel free to use it.

You can use sesh to save, list, find, merge, and split your sessions:

  • sesh snapshot

  • saves a snapshot of your current session in your project directory

  • sesh find “quantum computing”

  • This does full-text search across every saved session you’ve ever run, then you do sesh resume to drop you back in mid-conversation

  • sesh merge otherSession

  • e.g. pull another session into the current session. You can merge multiple sessions into one.

  • sesh split

  • allows you to split a session where you discussed three topics into 3 sessions each with their own topic and related messages extracted from the original session

  • sesh list

  • shows all your saved sessions in the current folder

Install in Claude like:
/plugin marketplace add m-gharibi/sesh
/plugin install sesh
