SIXTY DAYS. & placement ready.
A sober, mathematically balanced system designed around your 4-hour daily transit and college labs. Conceptual videos and documentation run during transit and lunch; active coding runs during lab typing and evening home deep-work slots. Zero sleep sacrifice (6.5h preserved).

Core Java Deep Fundamentals (the "why" behind JVM & Maps)
Detailed explanations of internal bitwise hashing, treeification thresholds, Red-Black vs AVL rotation overhead, equals/hashCode contract violations, and concurrent CAS mechanics.
React Fiber, Reconciliation & Concurrency (under the hood)
How React works internally: Fiber singly linked list nodes, workInProgress vs current double buffering, O(N) heuristic diffing, hook action queues, and automatic batching.
Production Capstone Project (architecture & interview defense)
Building one production-grade full-stack system (High-concurrency ticket/flash-sale engine) with deep understanding of race conditions, ACID locks, caching invalidation, and Docker observability.
