Budget App

It’s been kinda hard to make a frontend. I used Claude and God’s bless to create it but finally it does;)
I almost finished my project. Only thing left is deployment. See the frontend;)

Implemented all main features: auth, accounts, categories, and operations.

• Set up JWT authentication with argon2 password hashing
• Created User, Account, Category, and Operation models
• Implemented CRUD operations for all entities via repositories
• Added automatic balance updates when creating/updating/deleting operations
• EXPENSE decreases balance, INCOME increases it
• Created filtering by account_id, category_id, and date range
• Added /categories/with-balances and /operations/details endpoints for analytics

Challenges:
Operations were tricky -> had to properly revert old balance changes when updating. Solved with revert -> update -> apply sequence.

Complete API ready for frontend integration.

Started working on Budget App - a personal finance management application. Chose FastAPI + PostgreSQL stack, then I’ll write Frontend in React

• Set up project structure with layers: models, repositories, services, routes
• Created config file with database settings
• Configured database.py with engine and sessionmaker
• Added CORS middleware
• Created basic health check endpoints

Decided to use Repository pattern for DB isolation and Service layer for business logic. Should make testing easier ;) (i hope)

I just forgot to write devlogs workinh on this project, so don’t pay attention that I wrote first devlog after 4:31 hours of developing :(
