Show HN: My first dev project. Feedback?

Important context:

This project took 130 hours ± 5 hours from start to finish.

Before starting, I had zero experience or knowledge of:

1. Coding (knew that Python was a language and that's it)

2. Financial microstructure (didn't know what VWAP or option contracts were; let alone greeks, calls/puts, Bayesian optimization, etc.)

3. Tooling (Github, Postgres, Docker, Cursor, CLIs, etc.)

4. Software engineering principles/best practices

---

Questions I have:

1. Is the code objectively decent? I passed logic in plain English to AI, step-by-step, and tested before layering more

2. Is learning these domains and going from 0 to 1 in ~130 hours good - or laughably bad?

3. Does this signal any sort of nascent talent in the areas of SWE or quant finance?

(I'm trying to get an early signal of if I should continue to explore a career change. Or if I'm out of my depth.)

Any feedback would be massively appreciated.

Happy to provide more details/context :)
