I have about 4 years of part-time tutoring experience in St. Louis, MO for a private company and, in Edwardsville, IL for SIUE. I have additionally about 3 years of part-time and periodically full-time experience (2014 - 2017) with online or primarily online tutoring employers. I began this tutoring business in June 2017, which has been a full-time job. Since November 2017, I have had more than 2100 sessions with 224 students (as of Dec. 2022). Many sessions lasted 2 hours or more. Some students have had many sessions. A few students have been with me for years.

I am also open to helping with research projects, theses, or dissertations in any field (especially Heart Rate Variability (HRV)) requiring math, statistics, physics, programming, and certain areas of engineering if there is a good fit. I do not proof dissertations or theses. I do not provide statistical help for dissertations or theses.
Students of all ages are welcome. I have had C programming students as young as 10 and 14. In Java (AP CS), I have tutored 8th grade, 9th grade, and HS students. In addition, I have had several HS AP Physics students. I have had a 12th grader learning Java enterprise apps (then moved to C# .Net asp.net web forms). I have had one 8th grader and two ninth graders in advanced math classes. I have tutored math, physical science, and astronomy for a student in 7th grade. I have taught a 7th grader physics with a portion of Hewitt's Conceptual Physics (slowly). Currently I have a ten-year-old boy as a student learning Python for gaming.
I have had students in research, students working on their Ph.D. dissertation, students working on their MS thesis, and students working on their MS or MBA, as well as elementary students, HS students, and undergraduates in CS (mostly) or engineering. Some of my BS CS students want physics and/or math tutoring, in addition to CS tutoring. I have also helped an industrial research professional Ph.D. in C and C++. Lately, I have been getting more MS students working on CS-related degrees and adults interested in learning Python or C++. In the past several years, I have had several AP statistics students and several BS CS students in statistics for engineers. I have tutored students in AP calculus, calculus, differential equations, and introduction to linear algebra. I usually have college or university physics students.
I have a B.S. in Mathematics (SIUE), an all-but-thesis graduate coursework toward an M.S. in physics (SIUE), an M.A. in Physics (Washington U St. Louis), and a Ph.D. in Theoretical Physics (Washington U St. Louis). I also have a postdoctoral fellowship in Theoretical Physics in Germany (Universitaet Tuebingen, Institut fuer Theoretische Physik – Department of Theoretical Physics) in my background. I took the required classes for a B.S. in physics during and after my B.S. in math but did not receive a degree. I am two classes away from completing an M.Ed. in Secondary Education/Mathematics (UMSL), but it is now too late to complete.
As an adjunct professor, I taught Introduction to Statistics, physical science, and college physics. I have been a former teaching assistant or teaching fellow in physics for 5 years in graduate school. I am also an author or co-author of about 40 refereed journal publications and about 40 refereed abstract publications (mostly in medical research). I have about 2,650 citations, recorded by ResearchGate.
I am a former part-time software engineering consultant using C++ for a US industry in PA (2019). Additionally, I gained six years of experience as a programmer/software engineer. I had twelve years of programming experience in scientific research at Wash U School of Medicine in St. Louis. My dissertation and postdoc have provided five years of FORTRAN programming experience. At Wash U School of Medicine, I gained eight years of part-time UNIX system administrator experience. The programming languages C, C++, FORTRAN, Python, and Java are my computer programming specialties.
Based on 40 hours per week of programming, I have about 6.5 years of experience with C, 4 years of experience with C++, 2 years of experience with Java, and 1.5 years of experience with Python (primarily tutoring Python). I have several years of experience with shell scripting. I have coded GUI’s in MFC/C++, JavaFX, and Java Swing. In total, I have been programming for about 30 years.
In addition to math and physics, I tutor C, C++, FORTRAN, Java, JavaFX, Python, SQL (first semester), basic UNIX/Linux, and shell scripting. I can teach beginning to expert levels in all programming languages, except for Java, C#, and Python. Currently, I can help beginning and intermediate-level Java and Python students. I can also help with beginning C#, JS, HTML5, CSS3, SQL, and PHP. I have recently tutored several times a first course in MATLAB for engineering students. Over the past few years, I have had many students in data structures and algorithms and python programming. Recently, I have helped with courses in algorithm analysis, applied ML, and computer systems design, but I am not an expert in any of those courses.
I work with students online. I will offer classes online (Java, C, C++, and Python), where students can connect from different locations, and they may share the burden of my default rate. The default rate becomes $40 + $10 for each additional student. E.g., four students would each pay 1/4 of $40 plus $30. Twenty students are the preferred maximum for an online class. With My Zoom, 100 students can join an online class in real time. (Students must come together first and then request a class. I do not form classes.)
I practice patience and a perfectly positive attitude toward my students, striving not to judge others. In sessions, providing clear explanations of concepts is a focus, if there is a need. Otherwise, practice is the focus. Active learning is best in any subject. Teaching strategies in test taking is beneficial to many students. Teaching error-free programming techniques is valuable in CS.
I want to help students learn problematic material. It is possible to beat the fear of success through achieving small successes. The only real teaching/tutoring goal is to teach a student everything the teacher/tutor knows so that the teacher/tutor is no longer necessary.
Learning technical subjects requires problem solving, and learning programming languages requires specific programming practice. Reading programs, if done carefully, is helpful, but there is no substitute for programming. Like mathematics and physics, one must read and actively practice (program) to master the subject. With sufficient programming practice, there is no need to do rote memorization of code idioms -- such things will come automatically. Programming is problem solving, and I think it is more like problem solving in math than in physics. Learning programming is ideally like learning to play a musical instrument. Learning math and physics also requires significant practice to bypass rote memorization, develop problem-solving speed, and develop intuition.
I primarily write original code to solve problems, if I am paid to do so. The student should assimilate discussed or developed code during a session. It is essential to read and understand code in the relevant programming language.
Note that High School physics teachers with a B.Ed. have the weakest background in physics courses. A High School teacher with a B.S. in physics is much better prepared to teach physics. An M.Ed. high school teacher does not take as many physics courses as an M.S. physics teacher, and could still know less physics than a B.S. physics teacher. A Ph.D. in education teacher is like an M.Ed. in physics teacher in terms of physics courses, unless an M.S. in physics was earned. A Ph.D. in physics has the most experience in physics courses, and a Ph.D. in theoretical physics could be even better prepared. Postdocs also add to a Ph.D.'s preparedness to teach.

“Knowledgeable, patient, and proactive tutor!
Peter was the only tutor who reached out to me even if during the weekend. When we started having problems exchanging communications by XXXXXX, he proactively contacted me by phone. Considering that we live in different states, I considered it a great act of kindness and availability. He is extremely patient, and transmits, with calm confidence, that the goal will be achieved. In a moment so overwhelming, and full of homework to do, he was able to reassure me that I can do it. Overall, I could not be happier, and I strongly recommend him. I will definitely require his help for the rest of the course and for my future math classes. Two thumbs up!”

6 lessons Statistics
Lately:
The number of lessons provided to a student is an interesting measure of performance at this point (1/19/23). One student had about 350 sessions and another had about 200 sessions. Two others had between 130 to 150 sessions (both are still current students). Three other students had between 75 and 100 sessions (one is still current). Seven students had between 25 and 50 sessions (one is still current). Eight students had between 15 and 25 sessions. Twenty students had between 10 and 15 lessons, inclusive. Seventeen students had between six and nine lessons, inclusive. Nine students had five lessons. Eighteen students had four lessons.
(2024): Most students wanted help with discrete math, statistics, AP statistics, AP Calculus BC, algorithms, and Python. One student always requires JS and PHP. Some time was provided to help a student with SQL. Java tutoring was also provided. My newest Python student is 10. AP Physics C and AP CS were also tutored. One student is getting help with college algebra. Another required help with honors pre-calculus. Lately, I have had students in elementary math and algebra. The jc-pdllc.com website is now offline since it brings no new students.
(2023): During the Summer, a significant amount of college calculus and first-year university physics tutoring was provided. I taught Calculus 1 and most of Calculus 2 following Stewart’s text. Most recently, I have been tutoring discrete math, MATLAB, Java, Python, AP physics C, university physics (mechanics and E and M), geometry, AP Calculus, Calculus I and II, college algebra, and pre-calculus. I have begun helping an MS in physics student with a thesis calculation.
I have tutored several students taking AP CS with Python. There are 2 semesters for this course, and I am helping with the second semester now (03-23). Many of my other students are also learning Python with me - and they are not enrolled in a college or university. I spent about 100 hours expanding and improving the website for JC-PD LLC. The number of webpages for JC-PD LLC was doubled. The website uses HTML5, CSS3, JS, and PHP on a Linux VPS. SEO using web master tools and schema was also implemented. Significant improvements were noted.
(2021-2022): I helped code Python homework in a UAV engineering class - no problem except for control theory. Several of my CS students have graduated and are now employed or going to graduate school. In 2021, I had several students in linear algebra and diffyq. During this time, I have been getting more physics students, and the flow of Python, C++, and Java students has been steady. I have been helping more graduate-level CS students - those beginning CS at that level or doing degrees related to CS. One of my long-time students is beginning graduate school now. I will help them with CS courses. I have helped a student with C in courses that require some systems programming in Linux/Unix. An economics graduate student needed some background math help. That student is up-to-speed now. I helped with an advanced data structures class in Java. Also, I helped with a data science-type CS class (still not my cup of tea). Additionally, I had students in linear algebra, physics (1st year), AP CS, AP Java, AP Physics 1, differential equations, easy JS, java, C++, python, discrete math, and algorithm analysis. I helped with a computer systems design class, C++ data structures, JavaFX, and PHP. Currently I am helping with advanced data structures and algorithm (graduate level class for an IT MS student).
(December 2020)
There was a slight decrease in business due to covid’s influence, but it was reasonable nevertheless. I tutored data structures and algorithms in C, C++, and java (4 students). Also, I tutored SQL (several students), C (several students), C++ (several students), MATLAB, JavaScript, and python. In math, there were several algebra-1 students (advanced or honors), and one college algebra student. I helped with digital fundamentals for ½ of a quarter.
(June 2020)
I tutored a tough differential equations course, a linear algebra course, a discrete math course, and some calculus 2. Also, I tutored, SQL, C#, C++, Python, Java, C, Linux, Linux OS programming (threads and processes), PHP, HTML5, CSS, algebra, prealgebra, and a little Python game programming. I helped some students with data structures and algorithms and ½ of a computer organization course.
Several of my HS students have graduated. They will major in CS in college. Most of my students are CS majors, engineering majors, or economics majors at various levels in university. Some of my students are children in middle school. One student is a professional DDS interested in CS. I received a $100 gift card from the parents of one student.
(Dec 2019)
I just finished this semester tutoring C, C++, Java, python, discrete math, MATLAB, CSS3, HTML5, physics, math, a little C# with asp.net (still learning), and a little SQL. I also tutored a little JS, but still learning that too. The C++ course also had a little MFC with visual studio. My students were primarily college students, an experienced DDS, a seventh grader, ninth grader, and several HS students.
Consulting in C++ with Adept PD LLC was ended due to dubious practices on the part of Adept. Some schools, including junior colleges, are giving difficult or unreasonable (more difficult than the course level requires) homework assignments, presumably to reduce the student CS population.
(Spring, 2019)
I have tutored data structures in C, C++, and Java – multiple times in C++ and Java. There have been many Java students and C++ students, along with occasional C student and MATLAB students. I helped a student with a bridge course for students with a bachelor’s degree not in CS to enter a MS program in CS or a branch of CS (IT or cyber security). One of my HS JavaFX students is changing to ASP.NET C#. A young student of mine has left the country. I am a software engineering consultant in C++ for an industrial company, which will end soon since the project is essentially finished. My DDS CS student is now focusing on web development for the summer. My cardiologist Python student is on break, waiting for another cardiologist to be hired. Currently, I am tutoring and learning JavaScript, CSS3, and HTML5.
(The following was written Jan 2018.)
One of my recent students (Sheldon of VA) always said he learned more from me than his professor for his graduate-level physics class.
One of my current students (Khailen of VA), in 6th grade, only needs me to help prepare for math tests. He only needed four or five regular sessions to become clear with his mathematics.
Most of my Unix/Linux bash scripting students get one lesson and are content. One (Eric) has returned for one lesson again after three months. Once it is clear how to approach these programs, there is no longer any need for tutoring.
My MATLAB student (Lara from MI and my C++, MATLAB, and Python student (Melky) student both got A+’s.
