Coding With Joseph

Data structures and algorithms tutoring in the GTA

Data structures and algorithms tutoring for GTA students

Linked lists, stacks, queues, trees, recursion, Big-O, sorting, and exam tracing taught until the reasoning is yours.

DSA is where guessing gets expensive. We draw the structure, trace the code, analyze the runtime, then write it by hand until you can do it under test conditions.

Sound familiar?

You can recognize a linked list solution, but writing one from scratch still falls apart.

Big-O answers feel memorized instead of derived.

Recursion, trees, or graphs make sense in lecture and disappear during a quiz.

How the first session actually runs

You bring the thing that is going wrong: the assignment, the error, the failed quiz, the topic that will not stick. We find the one gap doing the most damage and fix that first. You leave with the problem moved forward and a clear next step, not a sales pitch.

What we fix first

The first session is not random tutoring. It is a diagnosis and a focused repair.

Linked list operations

Recursion call stacks

Tree traversals

Big-O exam reasoning

What better looks like

  • Trace pointers, nodes, recursion, and loop behavior on paper.
  • Explain time complexity instead of guessing from keywords.
  • Turn DSA assignments into repeated patterns you can actually reuse.

Questions

Can one session help with DSA?

Yes, if the target is specific. One session can clarify linked list insertion, recursion tracing, Big-O, or a tree traversal. Full mastery takes reps, but clarity can move fast.

Do you use diagrams?

Constantly. DSA is visual. If you cannot draw the structure and trace the state changes, the code will feel like memorized symbols.

Where students book from

Sessions are online, so it does not matter where in the GTA you are. Students book from across these cities and from outside them.

Need a different subject?

C++ / C

Pointers, memory, classes, structs, file I/O, and debugging explained until you can write the code without AI carrying you.

Java

Get unstuck on OOP, inheritance, interfaces, collections, exceptions, JavaFX, Swing, and data structures without hiding behind generated code.

Computer Science

A focused first session for students who need help with programming, assignments, debugging, AI dependence, or a course that suddenly got serious.
