From Bootcamp WebDev to Confident Full Stack Engineer

I came into web development as a career changer through a bootcamp. Luckily landed my first job around the same time GPT landed, and learned the ropes as fast as I could but with heavy assistance from AI. But deep down, I never really felt confident in my fundamentals. Their program taught me all the things I felt I was missing. I went from aimless feature development, anxious about being replaced, to genuinely understanding systems thinking, performance, and scalability.

Level-up your Software Eng Career

Bogdan and Dragos have put together an excellent resource to help engineers who are struggling to land interviews and/or level up. After joining, I learned how to write an effective resume, how to tell the kinds of stories hiring managers want to hear, how to study for and pass technical interviews, and how to be a better Software Engineer across the full stack.

One year to level up: my road to senior

That experience left me feeling confused, insecure, and full of self-doubt. I was stuck in tutorial hell and endless side projects. I started this program because I wanted to master end-to-end delivery and stop settling for second-tier companies. After one year I started feeling more confident, able to resolve problems effectively, and received an offer for a full-stack position.

My honest review

I've got to thank Dragoș and Bogdan. They really helped me learn the core concepts and fundamentals of programming. Without a solid foundation, I struggled to learn efficiently. That's what makes this program so great: it's structured in a way that just clicks. Each lesson builds on the last, so you understand why you need to learn something before moving on.
