Spent today making sure SpendSense doesn't just work โ it works safely. Checked that no API keys or credentials ever touched the codebase, added retry logic for when the AI service gets overloaded, made sure a single bad row of data can't crash the whole app anymore.Also spent a genuinely humbling amount of time discovering that "fixed in one place" doesn't mean "fixed everywhere" โ this app runs across three separate files now (the dashboard, a daily automated digest, and my testing notebook), and getting them to actually agree with each other turned into its own debugging exercise.Not every day of building AI looks like AI. Some days it looks like checking logs, renaming files, and making sure the boring stuff is actually solid underneath.2 days left in the AI Application Building Challenge. ๐ฅDecoding Data Science DDS Business Circle Mohammad Arshad#AIChallenge #BuildInPublic #AI #FinTech #Dubai
