Instructor Bio
I’m a backend software engineer and instructor from Romania with more than 14 years of professional experience. I focus on system design, databases, APIs, performance, and the practical trade-offs behind reliable software. More than 19,000 Udemy students have enrolled in my courses, and I share backend engineering lessons with a community of more than 60,000 YouTube subscribers. My teaching is concise, visual, and grounded in real engineering decisions—not memorized diagrams. I aim to help developers understand why a solution works, compare realistic alternatives, and explain their choices with confidence.
