Building a Persistent CLI Financial Tracker in Go

I recently set out to build a tool that solves the problem of manual financial tracking—without the bloat of traditional apps. My result is Safi-Budget, a Go-based CLI tool.

Technical Takeaways:
Data Flow: I implemented a JSON-based persistence layer, ensuring that every transaction is serialized and saved instantly.

Handling Windows I/O: By replacing fmt.Scanln with bufio.Scanner, I solved common terminal-freeze issues, making the app much more stable.

Testing: I added a main_test.go suite to validate disk I/O operations and ensure data integrity.

This project was a great way to refine my understanding of Go structs and file system interaction.

I’d love to hear your feedback on the implementation!
