I'm a Java specialist with 8+ years of experience building high-performance systems and coaching students to crack FAANG-level interviews. My strength lies in teaching Data Structures and Algorithms in Java the right way – clean, production-quality code with deep focus on time/space complexity and Java-specific optimizations.
I cover everything from scratch with zero fluff:
Arrays & ArrayList internals, dynamic resizing tricks
Linked Lists (singly, doubly, circular) – reversal, cycle detection, fast/slow pointers
Stacks & Queues using ArrayDeque, real applications like monotonic stack, sliding window
Hashing mastery: HashMap/HashSet internals, collision handling, custom objects as keys
Trees: Binary Trees, BST, AVL basics, traversals, LCA, serialization
Heaps: PriorityQueue tricks, kth largest/smallest, merge k sorted lists
Graphs: Adjacency list, DFS/BFS, topological sort, Dijkstra, Floyd-Warshall
Key algorithms: Two pointers, sliding window, binary search variants, greedy, DP (knapsack, LIS, etc.)
Advanced: Trie, Segment Tree, Disjoint Set Union when needed
All implementations are written in modern Java (17+), using generics, proper encapsulation, and JUnit tests. I emphasize patterns over memorization – once you see 100+ problems explained with the same 15–20 patterns, LeetCode Hard becomes routine.
My students consistently move from struggling with mediums to solving 20–25 problems in mock interviews. I focus on making you think like a senior engineer: clean code, edge cases, complexity analysis, and multiple approaches.
If you want clear, concise, interview-ready DS&A in Java with zero boredom and maximum results, I’m your guy. Let’s get you that offer.
