I am available to tutor math, computer science, and physics via Skype. I work with both adults (e.g. software developers looking to brush up on math) and younger students, especially students preparing for math competitions.

If you are looking for math contest prep, be sure to read the section about that below.
I am friendly, patient, and able to explain things clearly.
I have more than 10 years of tutoring experience and have worked with more than 100 students. I received my SB in Physics from MIT and am an experienced software developer.
I am also very familiar with math contests. I am an instructor at Art of Problem Solving, received honorable mentions on the USAMO and Putnam exams, attended MOSP and RSI, tied for first place on the Mandelbrot Contest, and was a member of the US Physics Team twice.
See here for my slightly out of date teaching resume.
During lessons I use a tablet device to write on a shared whiteboard. I recommend students use a tablet so that they too can write on the board.
For reference, my Skype username is seanmarkan.
Occasionally I'm asked about tutoring via email. I am happy to provide advice on math problems via email, and it's the same rate as Skype tutoring, pro-rated to the minute.
I leave it to the student to set the agenda for each lesson. I highly recommend that you bring a set of problems that you are struggling with and want to work through together. This is almost always the most effective way to improve.
The rate is currently $100/hr. You can book in increments of 30 minutes.
You can pay after each lesson or make a deposit in advance (for one or more lessons). I will refund any unused deposit upon request. PayPal, Venmo, Zelle, and checks are all fine.
You can use this convenient online booking tool to see my availability and book immediately, or alternatively feel free to email me at sean.markan@gmail.com.
If you make your booking through the online tool, you can also reschedule or cancel using the same tool—just use the links in the confirmation email you received when making the booking.
Please try to provide 12 hours notice if you need to cancel or reschedule. There is no fee to cancel with 12 hours notice. I reserve the right to charge a $20 fee to cancel/reschedule with less than 12 hours notice ($40 if it's less than one hour).
No-shows will be billed for the full amount, and if I cannot reach you within 10 minutes of your scheduled start time, you will also forfeit the remaining time.
Feel free to email me at sean.markan@gmail.com.

I receive a lot of interest from parents who want me to help their children with math contest preparation (for tests like the AMCs and AIME). If you are one of them, please bear the following in mind:
Improving at math contests requires a lot of work and motivation. If your child is not intrinsically motivated to work on them (or if you have to push them), I recommend that you do not choose me as a tutor. It is likely to be frustrating for both of us. However, if your child loves math and wants to learn new things as fast as possible, we're probably a good fit.
On a more concrete level, here are the expectations I have for students working with me on math contests:
Students must come to each lesson prepared with a list of problems to work through. (10 problems per hour seems to be about the right ballpark.) Students must have worked on these problems in advance, so that they can articulate what they tried and where they got stuck. (Or if they had no clue how to start, that's fine too.)
I recommend pasting the text of the problems into a Google document. This way I can see them easily during the lesson, and both the student and I have an easy way to review past work.
As for where to find problems to work on, it is generally a mix of problems I suggest and problems the student picks on his/her own (e.g. by working through old contests).
If you feel your child can enthusiastically meet these expectations, feel free to get in touch!
