My result is Safi-Budget, a Go-based CLI tool.</p> <p>Technical Takeaways:<br> Data Flow: I implemented a JSON-based persistence layer, ensuring that every transaction is serialized and saved instantly.</p> <p>Handling Windows I/O: By replacing fmt.Scanln with bufio.Scanner, I solved common terminal-freeze issues, making the app much more stable.</p> <p>Testing: I added a main_test.go suite to validate disk I/O operations and ensure data integrity.</p> <p>This project was a great way to refine my understanding of Go structs and file system interaction.</p> <p>Check it out here: <a href="https://github.com/shakipkorir/safi-budget" rel="noopener noreferrer">https://github.com/shakipkorir/safi-budget</a></p> <p>I’d love to hear your feedback on the implementation!</p> go showdev beginners opensource
