as software architect, and I find geofencing and driving behavior tracking very useful. The explanation of Haversine formula for distance is simple to understand. But for real road maps, it can be little difficult sometimes. Still, this is very helpful for building location-based applications.

I am working in software architecture and DDD is helpful for big systems. I like how you explain Entities, Value Object and Aggregates. It help in making clean code. But DDD is not easy, it need business knowledge. Sometimes for small projects, it become complicated. Still, Thanks for sharing!
