About David

Bio

I am a Physics Ph.D. with two areas of specialty: math and software.

I have 10 years of experience as a software Technical Support Engineer. I love helping customers. I have tons of experience with SQL, databases, Excel, Python, VBA (Visual Basic for Applications), Linux and UNIX (including shell scripting), VBscript with WSH, and troubleshooting everything you can imagine with Windows.

I have tons of experience with SQL, databases, Excel, Python, VBA (Visual Basic for Applications), Linux and UNIX (including shell scripting), VBscript with WSH, and troubleshooting everything you can imagine with Windows.

I have 15 years of experience as a math tutor, and I've worked with students from middle school through college and beyond, covering topics from pre-algebra and algebra through calculus and linear algebra.

I've been told I'm kind and really good at communicating with people at their own level. I'm also patient, happy to work with students at their own pace, and good at putting students at ease.

I have extensive experience working with Oracle, Microsoft SQL Server, and Microsoft Access databases, but I've also worked with MySQL, PostgreSQL, and SQLite. I have sample MySQL and PostgreSQL databases running on Debian virtual machines, a sample SQL Server database running on a Ubuntu Server virtual machine, and a sample Oracle database running on a Windows virtual machine. If you want to, we can use any of these virtual machines for practice.

I have used Python extensively for web scraping and for accessing all of the database types I've mentioned above. I've taken basic and intermediate Python classes. I've taken 1 year of computer science classes, so I know about basic data structures and algorithms. I have samples of my Python and VBA work up on GitHub.

I've done all sorts of insane things with Microsoft Excel, including using VBA anywhere from creating simple custom functions to complex functionality with multiple custom forms with various controls on them.

I've helped math students with a variety of difficulties, such as math anxiety, a tendency to make lots of mistakes on homework and tests, and teachers and textbooks that we're so good.

GRE,

GRE

I have 15 years of experience tutoring on many subjects, including the GRE. I’ve taken the GRE twice, plus I’ve taken many practice GREs, so I understand test taking strategies, which I will share with you. There are two keys to getting a great GRE score. First, understand the different types of GRE questions, which we can go over together. Second, take a number of practice GRE tests under simulated testing conditions, so that you learn to pace yourself and answer as many questions as you can. If you don’t have some, I can get you practice GRE tests.
Microsoft Excel

Microsoft Excel

I have many years of experience with Excel, doing all sorts of insane things with it: chains of spreadsheet functions, pivot tables, statistical analyses, charts and tables, custom spreadsheet functions using several lines of VBA code, even custom windows with hundreds of lines of VBA code. I’m also an experienced tutor and technical support engineer, with a talent for two things: 1) seeing where my students are, and then 2) telling them what they need to know in an easy-to-understand way at a comfortable pace. If you want to systematically learn Excel or parts of it, we can select a good textbook on Excel, and we can regularly meet for lessons and Q&A as you read through the textbook and work assignments. Or I can directly teach you the parts of Excel you want to master. We can work on spreadsheets together using Wyzant’s desktop sharing feature.

Computer

Linux,

Linux

I have years of experience using the Linux command line and shell scripting, including with sed, awk, and grep. I have experience working with Ubuntu Desktop and Server, CentOS, and Debian. I have imported and installed a variety of Linux distros into virtual machines in Virtualbox and VMWare on Windows hosts, and have networked together multiple Virtualbox guests running in parallel.

Microsoft Windows,

Microsoft Windows

I'm an experienced software technical support engineer who has worked with all versions of Windows since Windows 3.11. I have done extensive troubleshooting of problems with the Windows operating system and of programs running on Windows, including problems with slowness, crashing, errors, and malware.
Python,

Python

I have considerable experience with Python and computer science. My favorite development environments are PyCharm and PyDev. I've posted some of my Python programs online on GitHub. Wyzant likes to block out URLs, so here’s the URL in all English: https colon slash slash github dot com slash DavidJLambert slash Python-Universal-DB-Client. I also have experience with Java, Fortran, Visual Basic, and shell scripting. I have 15 years of experience as a tutor of math and software, and 10 years as a Technical Support Engineer. I have a talent for understanding what my students need to know, and teaching them at their own pace. Python is a common choice for a first programming language, partly because it is easy for beginners to learn. But it can still be a challenge to learn because Python has 3 different programming paradigms: procedural, object-oriented, and functional. These paradigms work very differently from each other, and that can be quite a challenge for people new to programming. Procedural is easy. Object oriented is quite different, and can be a challenge to get used to. Functional programming is not covered in a first course on programming, and is still harder to get used to.
SQL,

SQL

I have more than 10 years of experience as a Technical Support Engineer with SQL, and with 6 types of relational databases: Oracle, SQL Server, MySQL, PostgreSQL, Microsoft Access, and SQLite. I have lots of experience installing, configuring, and administering these 6 types of databases on Windows and Linux. I have sample databases of all 6 types available for you to use: Access and SQLite database files, and VirtualBox virtual machines with the other 4 types: Oracle, SQL Server, MySQL, and PostgreSQL. I also have 15 years of experience as a tutor, making me a patient, easy-to-understand teacher of technical subjects. I excel at figuring out where my students are, then giving them the knowledge they need at a pace comfortable for them. SQL can be a challenge for students. It’s not a procedural language where you give the computer exact steps to follow. In SQL, you tell the computer what results you want, and the computer figures out the quickest way to get your results.
UNIX,

UNIX

I have years of experience using the UNIX command line and Korn shell scripting, including with sed, awk, and grep. I have experience working with the Solaris and HP-UX operating systems and with programs running on them, including performance issues.
Visual Basic

Visual Basic

I have years of experience writing VB Script working with COM objects and the Windows Scripting Host for intelligently automating various tasks, including parsing the contents of web pages and running backups. I have also written VBA code for creating custom functionality in Excel, Access, and Outlook that includes custom forms. I have written Visual Basic programs. I do not have experience with the .NET framework.

Linear Algebra,

Linear Algebra

I have 15 years of experience as a math tutor, and I've worked with students from middle school through college and beyond, covering topics from pre-algebra and algebra through calculus and linear algebra. I've been told I'm kind and really good at communicating with people at their own level. I'm also patient, happy to work with students at their own pace, and good at putting students at ease. In linear algebra, the concepts are quite abstract. It is often the first rather abstract math class a student might take. When taking a class, it is common for many people to read about a concept or to listen to a lecture about it and think "OK, I get this," but when they try to do the homework problems, they realize "oops, I don't get it yet," and they have to go back and study the concept some more. This often happened to me when I was majoring in Physics (I ultimately got a Ph.D. in Physics). So I can do a good job of explaining those concepts, but to get a complete grip on the concepts usually requires working some examples of those concepts. I would recommend either watching me work a few examples of those concepts, or going through a few homework problems together. You can then do the rest of your homework problems on your own, and if you have trouble with some of them, you can come back to me: I can often set up a tutoring session with a few hours notice. It would help me to know some things about you: * What is your major? * What other math classes have you taken, and how did you do on them? * Why did you choose to take linear algebra? * Linear algebra requires a good grasp on geometry and trigonometry. How did you do on those classes? * Are you good at visualizing things in 2 and 3 dimensions? In trying to understand linear algebra concepts and homework problems, I recommend drawing pictures.

Effective Tutor for Challenging Topics

David is helping me improve my skills developing python code for Ubuntu operating systems using PyCharm. It was immediately obvious to me that his experience in these challenging work spaces is strong. Since I am effectively a novice, I was initially concerned we might have communication difficulties . However, this fear was quickly cleared as David was able to make the adjustments and explain important concepts in a clear way using terms that I could understand at my level. David establishes a comfortable and effective environment for leaning tailored to the my specific needs.

David does a great job explaining & going through materials - very patient and compassionate

So far, David has helped me learn the concepts of Python. He wants me to learn and does a great job of explaining the information/my questions and helps me understand what I need to do. We went through my homework assignment and he would ask questions while I did the assignment to make sure I understood why I was doing what I did. David has really helped me learn this class and is very patient. He cares about my success in this course and I appreciate his willingness and time he's taken to help me get up to speed. I highly recommend David for tutoring!

Trish, 3 lessons with David

Helpful and patient tutor in both Python and SQL

David L. was helpful figuring out the exercise I was stuck on and when he didn't have an immediate answer he took the time to figure out what I was doing wrong and got back to me with the solution the next day. He definitely helped me learn the lesson that was stumping me.

I must say, this is my first time ever using a online tutor session and I was very pleased with David. He was patient with me and helped me understand and solve errors in my code. I highly recommend David as a tutor.
