faq

How do sessions work?

We meet on a live video call. You share your screen, show me what you're working on, and we work through it together. Every session is live — no pre-recorded content.

How do I pay?

Venmo, Cash App or Zelle — the booking page fills in the amount and a note for you. No accounts, no card forms, and nothing is stored on this site.

What if my time gets taken or doesn't work?

Requests are confirmed by email. If two people ask for the same slot, I'll offer you the nearest open time — and if nothing works, you get a full refund.

Do you tutor beginners?

Absolutely. Whether you're writing your first for-loop or debugging a tricky React state issue, I'll meet you where you are and explain things step by step.

Can I book for a specific assignment or exam?

Yes. Mention the topic or assignment when you book so I can prepare relevant examples and exercises in advance.

What if I need to reschedule?

Email me at least 24 hours before your session to reschedule or cancel at no charge.

What video platform do we use?

Google Meet by default, but Zoom or Discord work too — pick one when you book.

free resources

Things I point students to between sessions.

LeetCode

Practice coding interview problems with curated topic sets and difficulty filters.

AI Engineering From Scratch

A practical GitHub resource for building AI engineering fundamentals from the ground up.
