Today wasn't about adding new AI features. It was about making sure NovaDXB can survive real users. A demo only needs to work once. A product needs to handle bad inputs, unexpected behaviour, security risks, API limits, and edge cases you didn't think about when you started building. So today I focused on everything users never see: 🔒 Input validation and sanitization 🔒 Prompt-injection protection 🔒 Secret management and deployment security 🔒 Rate limiting and caching 🔒 Error handling without exposing internal details And, of course, bug fixing. One of the more interesting issues: cached responses were returning the AI answer but not the itinerary data needed for the side panel. The chatbot looked correct, but the experience wasn't. That's the kind of bug users notice immediately. The AI itself didn't get smarter today. The product got more reliable. With only 2 days left, NovaDXB is starting to feel less like a prototype and more like something people could actually use. 2 days to go. 🚀 Decoding Data Science Mohammad Arshad DDS Business Circle #BuildInPublic #AIAgents #AIChallenge #Dubai #BuildWithAI #GenerativeAI #Innovation #SoftwareEngineering #CyberSecurity #UX

Spent today making sure SpendSense doesn't just work — 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" — 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. 🔥Decoding Data Science DDS Business Circle Mohammad Arshad#AIChallenge #BuildInPublic #AI #FinTech #Dubai

Took everything running quietly in the background — the classifier, the forecasting, the alerts — and gave it an actual screen. One click now pulls your spending, sorts it by category, shows you exactly where you stand against budget, and tells you in plain language if something's off. Also learned the hard way this week that "it works in my notebook" and "it works in the deployed app" are two very different sentences. Spent real time making sure the version people actually see matches the version I've been testing. It's live. It's rough in places. But it's real, and you can click it. 3 days left in the AI Application Building Challenge. 🔥 #Decoding_Data_Science #DDS_Business_Circle Mohammad Arshad] #AIChallenge #BuildInPublic #AI #FinTech #Dubai

I'm building SpendSense — an AI app that watches your spending as it happens and warns you before you overspend, not after. Bank SMS comes in → AI auto-categorizes it (food, shopping, travel, daily) → forecasts if you're on track to bust your budget → pings you on Telegram before it's too late. Less "oops I overspent again." One smart mentor for your money that adapts to how you actually spend. 8 days. Building in public. Let's go 👇 #AIChallenge #DecodingDataScience #BuildingInPublic #AI #FinTech
