AI Engineering
Learn LLMs, RAG, agents, secure tools, and production AI through practical insurance examples.
Why learn Python as a MERN engineer?
Many AI, document, numerical, and evaluation libraries are strongest there. I need enough Python to build and operate those services, but hosted model APIs and business orchestration can remain in Node.
Do type hints validate runtime input?
No. They help developers and type checkers. I use Pydantic or explicit validation for external data and carefully configure coercion/strictness where field values affect business behavior.
How do you make notebook experiments production-ready?
Move reusable logic into explicit modules and services, pin dependencies, remove hidden notebook state, inject clients, add meaningful boundary tests, and implement logging, resource limits, and deployment reproducibility.
An async endpoint freezes during OCR. Why?
The OCR library may be synchronous or CPU-heavy, so it blocks the event loop. I offload suitable work to threads/processes or queued workers and keep the HTTP boundary responsive with durable job status.
