Financial SaaS
Landing verified locallyTogetherly
A platform for personal and shared finances with circles, budgets, goals and joint decisions.

The challenge
Shared finances often live across spreadsheets, messages and personal apps. The challenge was to add transparency without removing each person’s individual space.
My contribution
I designed the product architecture and end-to-end experience: API, web application, landing, mobile foundation, brand packages, shared types and versioned legal documents.
Key decisions
- Model personal and couple Circles as the core domain rather than a layer added to individual accounts.
- Share brand, UI, types and configuration through pnpm workspaces and Turborepo.
- Keep privacy, traceability and approval of large expenses as visible product rules.
- Version terms and privacy notices with the code so every release stays auditable.
The product in use
Screenshots captured while running the project or reviewing its published version.

Outcomes
- The MVP brings together a complete API and web core, a public landing and a mobile foundation for the next phase.
- The architecture avoids duplicating rules and styles across product surfaces.
- The financial proposition uses direct language, clear states and short journeys.
