I used this course several years ago, and it was unquestionably a great investment.
My knowledge, skills and confidence improved massively, and I would recommend it without hesitation. I was skeptical at first but it turned out to be unfounded. These guys are legit and totally committed to helping you level up.

Bogdan and Dragos really know their stuff. The most valuable part of the course is the regular calls and getting feedback in the community.
Being able to bring a complex problem and a bunch of questions, discuss it with others, and then understand the problem deeply (not just at a technical level) is incredible. It's also fun, because others are on the same journey.

I can't overstate the value, in this software engineering game, of a community of likeminded individuals plus great mentoring and teaching, and that is what you're paying for here. Yes, you can theoretically get all the information yourself online - but it just doesn't compare.

They're also genuinely committed to making the course as good as it can be - I had one piece of negative feedback for them previously, which was that their time estimates were wrong, and they've since updated it. Overall, highly recommended.

I’ve really enjoy the programme so far. Bogdan and Dragos are both very helpful and always willing to give guidance, advice and tips.

The modules are kept up to date including recently the new themes surrounding AI, which makes it very relevant in today’s climate.

There is a lot to learn from full stack thinking, End to End Delivery to Software Architecture and more just to mention a few.

The various weekly calls are also really valuable, both for Q&A and for hearing different perspectives from other developers.

I highly recommend it!

This program has become my go-to program to get up to speed on full-stack JS fundamentals. It's more important now, more than ever, to really solidify your knowledge, practice your engineering skills, find community and a have a compass, pointing you in the right direction on how to grow and improve as a solid senior engineer and this is where I have found all those things.

I joined theSeniorDev program around March this year, and within only a few months, I can notice how being part of the community has changed the way I approach Software Development. Community support, frequent feedback from Bogdan, and the initial plan that is built based on your goals were the things that showed me this program offers a lot more than similar ones out there. I love being part of the community, seeing others learn and achieve their goals is a huge motivation!

This course goes into so much depth and is very well structured. The assessments make it clear which areas you need to focus on. Even only a couple of modules in, I have noticed a huge improvement in the quality of my code and my mindset.
And, of course it is challenging, but in the best possible way. Would highly recommend it.

The SeniorDev Software Mastery program is the best mentoring program for leveling up as a developer I have ever done! Dragos and Bogdan are experienced professionals in the software development field, and there is no lack in information that you can learn as a developer to ensure you reach a Senior level developer, and to prep you for the developer job search. In addition to a rich in information program that you follow, you also receive up to 4 mentoring calls per week with Bogdan and/or Dragos, to help you and answer any questions you have along the way.

Across one year, I worked through the entire curriculum, refined my CV to be invited to more interviews than I did before the program, and ended up preforming well on interview processes until I finally signed a contract as a senior developer at a top company.

Overall, I learned so much information from the program that will be useful to me as a developer for many years to come throughout my career. I have gained confidence in my work and in interviewing, and ended up having two great job offers from two great companies to choose from, and increased my salary by 65%. If you are looking for a mentoring program that will offer you everything you need to get to that next level, this is the one you should book. There is nothing else I have heard of that can compare, and it was the best decision I have ever made for my career!

I joined SE Mastery in October 2025 after watching some of the YouTube videos and finding the content valuable. At the time, I was actively interviewing for software engineering roles but felt I was missing some of the senior-level thinking needed to perform well in interviews and technical discussions.

Since joining, I have gained a better understanding of how experienced engineers approach problem-solving, system design, and technical decision-making. The content has helped me strengthen my fundamentals and think more strategically about software engineering challenges rather than focusing only on implementation.

One aspect I particularly appreciate is the practical nature of the program. The coding sessions and discussions provide insights into real-world engineering practices, and the personalized roadmap helped me focus on areas where I needed improvement.

Overall, SE Mastery has been a useful learning resource for my professional development, and I have found the program valuable in helping me grow as a software engineer.

A year later after completing the program this has been the best investement I have made in my career. The content is just what I needed to fill in my knowlege gaps and is aligned with in demand skill in the industry. It helped me to take ownership of my career and take on new challenges at work. What I love most about this program is the community. In a time where so many people are divided it's great to be a part of a community where I can learn from and am encouraged by developers all over the world.

I highly recommend this mentorship programme. It provides a well-rounded, end-to-end learning experience, covering frontend development, backend development, and CI/CD deployment. The content goes beyond the basics, diving deep into optimisation, scalability, and security.

One of the standout aspects of the programme is how frequently the content is updated to stay aligned with the latest industry trends and best practices. More importantly, the course helps you build strong mental models that make it much easier to apply what you learn in real-world work environments.

Bogdan and Dragos are genuinely fantastic mentors. They put a tremendous amount of effort into keeping the programme at a high standard. The weekly mentorship calls and guidance they provide were exactly what I needed to boost my confidence. Their advice is thoughtful, practical, and comes from real experience. It's clear that they genuinely care about helping people grow and succeed.

After 5 months of joining theSeniorDev program I was able to get much better job. Thanks to Bogdan and Dragos I was able to spot areas that I was not aware of that have so much impact on my CV and this was only the beginning. Following the course modules I was able to improve my knowledge and understading of fundamentals and DSA, which was very important during my interviews. The most important thing to me that I have learnt from DSA examples, was to always break the problem into smaller one, and write in the form of comments in the IDE what I am about to code and how it should work. It was for me a major shift, as I always though to "just write it".
I still have a lot to learn, however, the progress is visible and I was able to improve my knowledge thanks to theSeniorDev!

I love working with Bogdan and Dragos. What I love the most about them is their sense of building community. I've been able to talk about load balancing and other deep technical questions in a judgement free zone with international engineers. These multi-faceted perspectives have helped me to see the gaps in my knowledge and have exited me to grow as an engineer that can tackle problems in a scalable, professional way.

This program was exactly what I needed. I had been struggling to figure out the next step in my career, and Bogdan helped me put together a plan that was both down-to-earth and tailored to me, it took advantage of my strengths while clearly showing what I needed to improve. The program prioritizes building a senior mindset and core skills that are technology-agnostic and will remain valuable throughout my career. It was well worth my time and money.

TLDR: Go To Market mentoring services for software developers.
The program is rather exhaustive, they give you 14 days refund policy during which you can see other "students" who signed up in the previous months actually getting jobs.
The program is divided in modules, each module takes 1-4 weeks depending how much time you dedicate and your previous level. Modules include frontend, backend, fullstack thinking, end-to-end delivery, job hunting, etc.
You'll get life long learnings, especially in the job hunting module where specific tools, tips, and insights make the whole difference.
Re communication you have two main channels, the forum and the various group weekly calls.
You def has some gems in the program, worth taking, especially if you think the bump up in salary will be at least as high as the cost of the program. Which I have seen work very well for many students.
Last but not least, it's not a silver bullet solution, you will have to dedicate time and effort, job hunting is mostly hardcore hustling, and learning new tech skills is mostly what you already know how to do but in a slightly different format.
Good luck, and thx Bogdan and Dragos. Was a truly special experience, love the passion you guys put into your work.

After years of feeling stuck, this program helped me land my first senior engineer role & be able to hit the ground running. I think one of the most important parts is the focus on teaching you ways of thinking and approaching engineering like a senior (and applying what you learn). The program offers a huge amount of resources and knowledge-sharing, but Bogdan and Dragos helped to tailor the plan to my specific career goals so I could navigate it all in the most efficient way.

Dragos and Bogdan have been helpful with giving direction and guiding learners through their curriculum. I enjoy this program because they stay up to date with the AI frenzy, have weekly meetups and respond promptly to all questions. I truly believe if you have the time you can utilize this program to go as far as one’s desire.

A fantastic experience that dispelled the doubts I’d previously had, helping me to reach a higher level and become a much better programmer – more confident, more disciplined, and with a broader understanding of the bigger picture of what I do.

I've been through this program twice. The first time, I ended up landing a job with a significant salary increase (around 20%). Two years later, while on parental leave, I decided to revisit the material and it paid off again: I ended up joining one of Germany's top companies.

Dragos and Bogdan are great mentors and they curated quite a comprehensive curriculum, including frontend, backend, DevOps, architecture, CS fundamentals and inteview prep.

If you're a JavaScript/TypeScript developerlooking to level up, it's absolutely worth the investment. In my case it paid for itself in no time, twice!

Came across this program on YouTube last year during my unsuccessful job search in a very tough market.

Hesitated initially but decided to give it a shot and I couldn't be happier about my decision.

Getting hardly any interviews, struggling with self-confidence, being stressed with visa issues, in just a matter of a few weeks, I got organized, started getting several job interviews every week and got an offer in 3 months after starting a program.

Bogdan and Dragos are very supportive and skilled at their job. Their individualized approach helped me eliminate a lot of noise and focus on what's important and it paid off big time.
Furthermore, a great community of like-minded people supporting and encouraging each other on regular basis.

Best investment I've made in my life.

It was like being a talented athlete failing over and over and then finding a mentor that helps you unlock your potential.

If you are a someone who wants to master software development seriously, be part of wonderful and supportive community of professionals , fill in the gap in your technical skills, have a clear tailored 3-5 year plan for you based on where you are from technical and career perspective, then this program is great fit for you.

I am very grateful for Bogdan and Dragos for building this amazing program. They have helped me and many other engineers with senior thinking, fundamentals, different mental models that all together improved my skills and confidence. I have gained lots of technical in depth knowledge from different modules on improving Web Performance, Frontend Tooling, Backend Fundamental and API Designs, End-To-End Delivery with CI/CD and many more.

Program and the community is great place to be in and at the same time requires commitment, dedication.

I strongly recommend it to anyone who is serious about their career growth and wants level up.

I got into this program after following their YouTube channel.
Bogdan and Dragos are so professional, and they know exactly what points any developer is missing to become a real Senior.
They teach mental models (such as how to dress, what to say, how to arrange your work environment, how to be more productive, work-life balance, they touch everything!), and technical models as well.
They give real hands-on practice that gets you on the right track and gives you everything you need to pass interviews or get promoted.
Beyond all the above, they lead an amazing community of devs who share knowledge, challenges, and wins, consult with one another, and push one another to reach our goals.
I couldn't recommend more. This is an absolutely great program, don't miss it!
