About Dennis
Personalization means we start where your current knowledge ends. Coding is not magic. Absolute beginners and intermediate hobbyists alike benefit from my library of free code templates and cheat sheets.
We will tackle APIs, C++, JavaScript, SQL, HTML, and CSS to build a complete technical toolkit. Some students need help with algorithms or competitive platforms while others focus on backend architecture.
You will learn to debug your own scripts rather than just copying logic from the web. I have 10 years of experience simplifying these concepts for diverse learners. It is quite satisfying to see a script execute without errors for the first time.

Transitioning from finance into heavy coding felt like learning a second language through trial and error. I discovered that syntax is simple but the logic is where most people get stuck. Coding for analytics has been my main focus for 10 years as a practitioner.
My Master of Science from Columbia gives me a perspective on how databases scale in real environments. You need to know how to structure code before you can make it run efficiently. I prefer a direct style that cuts through the noise of modern development tools. Coding is simply a bridge to solving problems.
