Max Forbang
Software Engineer · US
I was able to negotiate a freelance web design deal for $5k and increase my salary by $45k at 23 years old. If the money is an issue for you, the only thing I'd say is that there is a reason why the most successful people spend tens or hundreds of dollars on couching / courses throughout their lifetime. It's because it's the most ROI investment you can make - the stock market or a 401k will not make you wealthy; you've got to figure out how to flat out earn more money.

Chris Joiner
Senior Frontend Engineer · UK
I wanted to fill my gaps to the Senior level and have already done side projects and online courses. I was looking for something more efficient, that's when I found you.
Daniel Roberts
Software Engineer · UK
This course / resource has given me the confidence to call myself a senior developer. Really supportive team with quick answers to your questions and the content is great, you can apply it to all languages and technologies. If you are looking to become a senior then this is the course for you. i got a 50% increase in pay within 6 months.
Pepa Sab
Senior Software Engineer - UK
I joined the programme because I was overwhelmed, jumping to multiple udemy/youtube course, trying to catch up with the crazy framework heap, never got the solid fundamentals of front-end development. I wanted to fill in the gaps, get better and start thinking like an engineer. As a result I got an offer close to six figure in a recent job hunt.
Ricardo Kreyhsig
Senior Sofwtare Engineer · US
I had hit a plateau and knew that I needed to make a significant change to level up, and the program delivered just that. Bogdan and Dragos helped me identify and fill my knowledge gaps, and the technical exercises and lectures were top-notch.
Laura White
Senior Developer · US
It was a shortcut. You got me straightened out.
Nabil Eldirsi
Lead Frontend Engineer · UK
About 4 and a bit weeks later I'm in a new role with a 33% increase in salary, more confident I passed more tech tests than I have ever before during the interview process. Now I'm leading a project in my new role, and I honestly wouldn't have gotten here if it wasn’t for Dragos and Bogdan at seniordev.com. Thanks guys looking forward to continuing my journey as a senior dev with both of you and the rest of the community.
Software Engineer · US
I have to say that joining the Software Mastery program has been one of the best decisions I've made in my career as a software developer! What really surprised me is how much focus there is on developing the right mindset for success - it's not just about the technical skills but also about how to approach everything in software engineering. And let me tell you, the results are real! Within just a few weeks of starting the program, I got a big pay raise and even more opportunities started coming my way.
Jana Kunft
Principal Engineer · UK
This program has been and still is absolutely invaluable for me, and I highly recommend it to everyone. I already landed my dream job of senior developer, aiming for principal engineer earlier this year, but as I have started developing a long time ago, and in my previous job I used obsolete technologies due to out of control technical debt. Dragos and Bogdan are amazing mentors.
Izaak Chater
Senior Engineer · AU
When I first signed up, I was struggling with self-doubt and anxiety, but within weeks of starting the program, I secured multiple interviews and eventually landed a job. Six months into my new role, I negotiated a 50% salary increase with back pay. This program taught me to focus on timeless principles in software development, cutting through the noise of ever-changing frameworks, and gave me the direction I needed to succeed in my career.
