Grand Milestone Update: Engineering Simulation Engines, Computational Geometry & Game Logic! ⚡🛠️

Hello LinkedIn Network! 🚀

I am back with a major milestone update on my Java backend journey! Moving completely past basic syntax exercises, I have spent the last few weeks engineering modular, state-driven console applications, multi-tier geometric models, and robust logic engines.

To continue documenting my #LearnInPublic progress, here is a detailed breakdown of the 4 core systems I designed, optimized, and pushed to my repository this week:

🏧 1. AtmEngine.java (Stateful Transaction Engine)

Engineered a production-inspired banking hub. Designed a multi-phase workflow featuring a strict authorization layer inside an infinite execution loop ( while(true) ). Integrated sequential state validation counters that automatically lock the terminal session after 3 consecutive failed login attempts.…
