I am a full time, professional online tutor of Computer Science (from school level up to college courses) and Mathematics (to school children).

I hold BSc (St. Xavier’s College), MSc and MTech degrees (Calcutta University) in Computer Science and am a state topper being a Summa Cum Laude in all of the three.

I started teaching about 12 years back, when I was in college. After tutoring both local and online students for many years I shifted to full time online tutoring about 5 years ago.

I tutor students from USA, Canada, Europe, UK, Singapore, Australia, UAE, India and others. My class timings are often flexible as I always keep the needs of my students in mind.

I teach various Computer Science topics including C, C++, Java, Python, C#, Data Structures, Algorithms, DBMS, solving projects/assignments etc. (this list is in no way exhaustive) mostly to college students. I also teach Computer Science and ICT to school students according to international boards like GCSE, IGCSE, IB and also national boards like ICSE, ISC and CBSE. I provide training for AP Computer Science A and AP Computer Science Principles as well.

I also teach Maths to school students up to Grade 10 being well versed with the intricate details of such courses ranging from the Common Core Maths of the USA to the Canadian board, UK GCSE, IGCSE etc. I provide tons of extra practice materials which we go through together. This is sufficient to instill confidence in them while getting the students exam ready.

I usually teach one-on-one since this allows close interaction with my students, but group tuitions are also welcome. This helps me to analyze their weaknesses/strengths and curate my tutoring methodology according to the individual student's mental prowess and the demands of the course in concern.

I always maintain a nice, cordial atmosphere in class and make sure that my students can speak to me freely. They are encouraged to maintain an open, inquisitive nature and ask questions till all their doubts are answered.

Students may also contact me for troubleshooting via phone, whatsapp or email if necessary.

I teach via Skype, Zoom and Discord. I employ online digital whiteboards and other paid digital solutions coupled with state of the art hardware setup for stutter free, crisp audio video leading to a fulfilling learning experience.
