FAQ
What does the Premium package include?
The Premium package includes a 1.5-hour live 1-on-1 online session covering advanced DSA topics like Graphs, Tries, AVL, Red-Black Trees, B/B*/B+ Trees, DP, Backtracking, and more. You'll also receive clean code, detailed notes, and a recording of the session.
Can I choose as many topics as I want to learn?
Yes, but I might not be able to cover all of them in one session which means you will have to book another one so keep that in mind.
What programming languages do you use?
I use Python and C/C++. But for understanding data structures to the fullest I recommend C/C++.
What does the Standard package include?
The Standard package includes a 1h live 1-on-1 online session covering these intermidiate topics: Circular Arrays, Circular Queues, Doubly Linked List, Sorting, Recursion, Basic Trees, Binary Search, 2/3 Pointers algorithm. You'll also receive notes and a clean code.
What does the Basic package include?
The Basic package includes a 1h live 1-on-1 online session covering basic DSA topics like Arrays, Strings, Stack, Queue, Linked List. You'll also receive notes from the session.

Very knowledgeable at DSA problem solving, good lesson structure with in-depth explanations and adjusts to student needs when necessary. Every lesson was filled with lots of useful information, was hard for me to keep up sometimes, but hopefully I can understand at that level someday :) Thanks!

A great first lesson with David. He introduced the relevant data structure and the complexities of Big O notation, explained how they applied to the LeetCode problem, and by the end I understood not just the solution, but the reasoning behind it.
