A personal finance platform: accounts, budgets, credit cards, loans, assets, and multi-currency tracking. In active development, with plans to become a standalone product.
What it is
Monetia manages the full picture of personal finances: bank accounts, credit cards, loans, budgets by category, recurring transactions, investment assets with valuations, and net worth over time. It handles multiple currencies with exchange rates, which matters when your financial life spans more than one country.
Why I built it
I work in FinTech, and Monetia is where I apply that domain end to end on my own stack: the data model for money movement, the edge cases of transfers and refunds, budgeting math, and multi-currency accounting. It runs privately on my own infrastructure today and I am shaping it into a real product.
An app AI agents can use
Monetia exposes its domain as an MCP server, so an AI assistant can check budgets, record expenses, or analyze spending conversationally, using the same domain layer as the web UI. Designing one API surface that serves both humans and agents is a theme across my personal projects.
