Turning a Rough Fintech Idea into a Build Plan
PRD, 69-parameter architecture and Figma delivered. Cancelled afterwards over an external API.
Problem
- A broad stock-screener idea, with no product direction yet.
- Investment analysis is complex: which financial parameters matter first?
- Engineering needed an MVP it could start on.
What I did
- Narrowed the idea into a defined MVP scope.
- Mapped 69 financial parameters across three tiers.
- Wrote the full PRD for the engineering team.
- Designed and delivered Figma prototypes as the handoff.
- Worked with the former CTO of HepsiJet throughout.
Three decisions
Three tiers, in decision order.
Descriptive, fundamental, technical, following how investment decisions are actually made.
A clear MVP line.
Must-haves separated from later phases, so engineering had a starting scope.
Hand off a prototype, not only a document.
Engineering got a visual reference as well as the spec.
The screener
Where it ended
The PRD, parameter architecture, and Figma prototype were completed and handed to engineering. The project was later cancelled over an external API issue. There is no shipped product, production usage, or analyst adoption.
