About Ange Gauthier

Want to make rapid progress but don't know where to start?

With 16 years of experience in IT and over 1,000 hours of online teaching, I help you develop your skills through one simple approach: learning by doing.

No unnecessary theory here! We focus on your projects, your challenges, and your goals. Every lesson helps you build practical skills and make real progress at your own pace.

From our very first conversation, we'll assess your current level and create a clear, personalized learning plan tailored to your needs.

Let's discuss your goals and build your success, one lesson at a time!

About the lesson

Have you been mixing up INNER and LEFT JOIN for a year, got a schema to design, or feel drawn to data? This course is for high school and university students (NSI, BTS SIO, BUT, bachelor's degree), web and mobile developers who want to secure and optimize their databases, and people transitioning into data analyst or backend roles.

My method: you design your own database from the very first lesson, built around a project that speaks to you (library, CRM, e-commerce). Each concept is applied immediately to a real dataset, not fictional tables. On the program: entity-relationship modeling, MySQL (DDL, DML, all JOIN types, GROUP BY, subqueries, views, stored procedures, triggers, indexes, ACID transactions, 3NF normalization), MongoDB (CRUD, complex filters, aggregation pipeline, indexing), integration with Python, PHP, or Node.js, DBeaver, MongoDB Compass.

Observed results: independently writing complex three way JOIN queries by the 3rd session, normalized and optimized architecture within 6 to 8 weeks; several students landed a data analyst or backend position. Formats: one off, regular (6 to 8 weeks), or intensive. No prerequisites required. First 30 minutes free: build your first working database together with me.

An excellent tutor! His explanations are clear, his exercises are practical, and his patience is remarkable. I finally understand Excel features that used to seem complicated. Highly recommended!
