Day 5️⃣ Cleaned up the API structure⚙️ 🔸Added prefixes + tags across all endpoint files and updated main.py 🔸Added a dedicated router.py to keep things scalable. 🔹Not a feature-heavy day, but this cleanup prevents future routing messes

Python but with FastAPI! There are a lot of reasons but if broadly talking it has: - async speed - dead-simple syntax - auto-generated docs - and zero boilerplate If you're building a backend today and not picking it, you're wasting time and performance.

what's the best programming language for backend?

Day 4 of building FinGuard ⚙️ Added the transaction_service.py file, this is where all the core logic lives🔥 Validation → DB ops → idempotency checks → fraud pipeline triggers, everything flows through this layer. #buildinpublic #fastapi #backend

PCs took decades to reach the masses. But AI agents? 🤔 They might spread much faster(even to non techies), transforming security, workflows & business ops. Looking at India’s digital momentum, I feel this leap is very likely. Do you think 🇮🇳 is ready for an AI-first era? 🚀
