Trader Performance Tool Prototype

I'm looking for a web app prototype for a trader performance tool called MRT. The main functionalities should include:

- Daily P&L tracking
- Journal entries
- Emotional state tracking

The user interface should be minimalistic and clean. For emotional state tracking, I prefer text descriptions.

Ideal Skills & Experience:
- Experience in web app design
- Strong UI/UX skills with a focus on minimalistic designs
- Familiarity with building tracking tools and journals
- Ability to represent complex data in a simple, user-friendly manner

Please provide examples of similar work done.
