Bio

I am a married (over 35 years!) father of two wonderful daughters and have enjoyed - and been relatively successful ;-) - working with / teaching children and young adults since I was a teenager, and people of all ages throughout my adult life. I put myself through school by tutoring elementary and high school students.

I am a married (over 35 years!) father of two wonderful daughters and have enjoyed - and been relatively successful ;-) - working with / teaching children and young adults since I was a teenager, and people of all ages throughout my adult life. I put myself through school by tutoring elementary and high school students. I also coached 8–15-year-old boys, football, and hockey, and worked at summer camps for a number of years teaching 6–16-year-old (male and female) photography (camera and darkroom). I was a teaching assistant for 2.5 years for an introductory computer programming class for non-computer science students while working on my Masters degree.

I hold both Bachelor of Computer Science, with Distinction (Honors) and Master in Mathematics (specializing in operating systems) degrees and have worked in the software industry for over 40 years. Throughout my career I have held a variety of development (programming), design, and management positions, up to and including executive (C-level) management. Many of these were as an independent contractor, which I have been for over 25 years, which has honed my ability to quickly assess and focus on critical (student's) needs.

I am flexible on scheduling time and am extremely comfortable tutoring both online (which in many cases works *better* than in-person) and in-person. I also try to be highly responsive at answering Wyzant Messaged questions.

Both professionally and personally I have been told that I am an excellent mentor, very easy to learn from, and a great listener.

I look forward to helping you achieve your academic, personal or professional goals!

Photography

I have been interested in photography for many years and even considered a career as a photographer until I became interested in computer software;-)! I have worked as a semi-professional photographer and taught many summer campers (6-16 year olds) both camera and (B&W) darkroom skills. I have taken a number of photography courses and have a good understanding of composition, lighting, shading, highlighting, cropping, etc. I can teach camera, as well as black and white darkroom, techniques.

The best coding tutor I have had

David has become my go-to tutor for learning how to code in C. I have been really apprehensive in my coding courses and constantly stressed feeling like I do not understand what I am trying to do or even how to explain what I do not understand. When trying to work with TAs at school or even other tutors, I have often left sessions in tears. David has really turned coding around for me. From our first session, he was kind and patient with me and helped me understand not only what issues I was running into while coding but also the logic behind it. David takes the time to help me understand the concepts as a whole, talk out how I am going to approach my code, and tackle specific areas that I am hung up on. He genuinely cares about my understanding and has checked in with me after our sessions to make sure I grasped what we discussed. After each session, he has put together recaps so that I can look back on them while I continue to work through assignments and fill in gaps from what is covered in my lectures with additional resources. I could not recommend David enough. He has helped me more than any other tutor has, not only in my comprehension of C but my confidence in software development as well.

Madison, 10 lessons with David

Incredibly knowledgeable and great at teaching

I had a great time learning about C++ particularly operating systems (graduate school level) with David. We dived into some pretty tough stuff like linker emulators and OS scheduling simulators, and I couldn't have asked for a better guide. He has a knack for breaking down complex ideas into something I could actually get my head around. Additionally, David was very patient and always found time to answer my questions. Scheduling sessions was a breeze too, which was a huge plus. Would highly recommend David if you're looking to understand the nitty-gritty of operating systems, especially the tricky parts.

Caleb, 7 lessons with David

Excellent!

As someone who strives to be a great teacher myself, I feel confident saying I know a good one when I see one. And that is David. This, in my opinion, is evident not simply by knowledge but when they ask, ‘are you understanding this?’ and/or ‘is this making best use of your time?’; each of which was asked multiple times. Definitely looking forward to working with him in the future and highly recommend.

Demitrus, 133 lessons with David

Knowledgeable, Patient, Fun, Interesting

I enrolled into a computer programming class with no prior experience and found myself overwhelmed with the information presented. I found David and my experience in the class was immediately better as I was able to understand the materials through his guidance. He is great at explaining how something works and relating what you learn to your interests.

Jet, 6 lessons with David

Extremely knowledgeable and Helpful!

David has been an invaluable resource in getting me back on track in my Operating Systems course in C. Prior to our tutoring sessions, I was destined to fail the course. David has been able to help break down complex concepts, such as parent/child processes in a shell, multi threaded processes, as well as network programming to implement a client/server program using function calls like send(), recv(), listen(), etc. David clearly has an extreme amount of knowledge in operating systems, and coding in general. He has been very helpful and patient when working with me, and I have always walked away from our tutoring sessions feeling much better about the assignment at hand. He has gone above and beyond, helping me debug code issues in replit outside of our tutoring hours. Would highly recommend!

Nick, 5 lessons with David

Extremely helpful and patient tutor

David tutored me throughout my undergraduate semester in both Computer Systems Organization and Object Orientated Programming. David was instrumental in my success in this class, and helped me master the material covered throughout both courses. He gave me the exact support I needed and would even try to find additional content that would further my understanding of the sue subject. Overall, David was an amazing tutor and I would recommend him to anyone.

Anadi, 13 lessons with David

Knowledgeable and extremely helpful tutor

Talked about VS code, how command line arguments are passed to the debugger and much more. Was able to cover material quickly and efficiently and I learned a lot in our one hour session! Thanks David!

Rebecca, 5 lessons with David

Helped me so much with my homework!

I needed help with C language and my computer science homework for my university. David helped me with my homework, and he also helped me understand concepts I was not understanding in my class. He responds quickly and is always there to help! I would definitely recommend him to anyone who needs help with coding!

Ramona, 4 lessons with David

great teacher, helped me through my long assignments

David is a great tutor, he helped me through my assignment even though I was slow through it and it was frustrating at times, he didn’t give up. Constantly pushed me to keep writing my code eventhough I had almost given up.

Yash, 4 lessons with David

Knowledgeable and Caring

David helped me with one of my CS courses that focused on Operating Systems in C language. He really made sure to break down all the parts to my projects and how everything links together. He really cares for your grade while also wanting you to learn the material and actually understand it. Can’t recommend him enough!!!!
