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.

Free problem triage first. Then focused 1:1 tutoring at $40 CAD/hour, no contract.

Online for students in Canada and the US · 500+ students helped · 8+ years teaching

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 triage actually runs

  1. 1

    You bring the problem

    Send the course, deadline, and the assignment, error, or exam topic that has you stuck.

  2. 2

    I reply with a next step

    I review the details and tell you whether a focused tutoring session is the right fit.

  3. 3

    We work through it together

    In a paid 1:1 session, we work on your code or topic and leave with a practice plan.

Academic integrity stays clean: I help you debug, trace, and understand your own work. I do not write submissions for you.

What we fix first

The triage is not random tutoring. It is a diagnosis and a focused repair plan.

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 areas and nearby campuses.
