A Non-Tech Founder's Experience
I am still using Codementorx as I write this, and absolutely love the company. From the onboarding process, to finding and working with the best Developer(s) for my project, everything has been amazing. Any questions I've ever had have been thoroughly answered and the customer service is unparalleled.
Outstanding Work Coding My Algorithm By Edaqa and CodementorX
This is an unbiased opinion. I am not getting any incentive for this opinion. I would like to let the world know that my dream of writing my own Forex Trading Algorithm has become a reality as a result of the professional programming services provided by Edaqa Mortoray one of the outstanding programmers over at CodementorX. So, if you are like me and is looking for a trusted company to build your algorithm, Edaqa and CodementorX is a great place to start.

I absolutely love Codementor
I absolutely love Codementor. I think it’s a real treat for the development community and for companies to hire developers when they’re getting up and running and also scaling.
Emiliano at Codementor has been extremely kind and efficient. I really enjoy working with him and want to continue working with Emiliano and people like him at Codementor.
Codementor is a breath of fresh air
Codementor is a breath of fresh air. The entire experience was unlike anything I had experienced before in the last 12 years being in the industry. The team is extremely friendly, knowledgeable and responsive and the talent they source for you is truly world class. I've completely stopped looking in other platforms because the time and money saved for the quality of finished product just cannot be beat. If your sick of the low quality high priced talent on Upwork or the broken customer experience with Toptal then you've got to get on Codementor NOW.
Great experience
Great experience. Quick and easy way to find a top tier programmer. The coder I worked with was excellent
Great experience
This company is professional, responsive, and dedicated to keeping their clients happy. They have been swift to respond to me at every stage and they put me in touch with a great developer. Their vetting process has saved me a lot of headaches. I will use them again.
Impressive candidates, easy process, great results
Codementor gathered a shortlist of qualified candidates to help me with some DevOps work. So far, I could not be happier with the results. The candidate I chose is concise, easy-going, knowledgeable, and provided suggestions that I had overlooked for this task. He completed the work within the estimated timeframe, and I have chosen to continue working with him.
Professional and unique in the industry
Professional and unique in the industry
I've been a long-time mentor on the platform and for a year we are using CMX that helped me build a profitable business. The team is easy to talk to and they are always helpful figuring out the various issues you can face while freelancing.
Without CMX our sales pipeline would've been way less stable and they save over 50 hours compared to other platforms for each deal (this is specific to our statistics).

I usually get high-quality developers that work with me and answer all of the questions that I have for them to help me improve as a developer and produce amazing programming material.
Delivering the expertise to make a project happen.
We were looking to augment our team with senior user interface development capabilities. Given a startup with a tight budget and having already suffered through some inconsistent delivery, it was important to find not only the skill set but a cultural fit for the team. Paul at CodeMentorX worked thoughtfully to understand our constraints and requirements and delivered a set of excellent candidates almost immediately. We have been engaged with Stuart through CodeMentorX and the difference is night and day. Not only have we been able to progress towards our launch milestone, but we have been able to create a much better platform foundation for the future.
I would wholeheartedly recommend CodeMentorX as a key resource to deliver the expertise to make a project happen.
Team sets them apart from similar services
The Codementor team is thoughtful, responsive, and genuinely committed to helping companies succeed. We worked with Codementor when kicking off a major web project that we needed a bit of extra capacity for. Unlike some competitors, we felt that there were real, caring people on the Codementor side. And, they helped us find a wonderful fit. Platform and payments are easy – definitely recommend all around.
Excellent company
Excellent company. Amazing Team. Top source for finding top-tier developers.

Codementor is our #1 way of scaling our engineering team
When we set out to find a full-stack engineer, we focused our search in a couple different areas - traditional job posting sites and freelance engineering marketplaces. But we quickly realized that job posting sites lacked the ability to filter out unqualified candidates. And while the freelance marketplaces did a bit better, they recommended candidates that were overqualified, out of our budget, or out of our timezone - or all of the above.
Then we found Codementor. The process of filling our position took less than a week and they found us a superstar. They've had the flexibility to meet our specific needs every step of the way and their customer service has been top notch since day one.
Codementor continues to be our #1 means of growing our engineering team and we couldn't be happier!
Get your product shipped!
We've worked with contracting firms of all shapes and sizes, and we've been thrilled with the experience of CMX. Pienso, an MIT spinoff, is building a machine learning training platform that enables domain experts to create, shape, and deploy their own machine learning models at scale - no programming experience needed. That being said, finding talent that can execute on such a technically demanding platform is an extremely difficult challenge.
CMX jumped right in. The hiring consultants we worked with had a great understanding of our technical requirements. They promptly matched us with an absolute rockstar DevOps engineer that was able to quickly and professionally execute our infrastructure goals to help bring our product to market. We look forward to working with CMX more in the future!

Great platform for mentors and clients
Great platform for mentors and clients. I've been using the platform for a few years. I've had many live sessions and I've found long-term clients too.

Love Codementor X…

Higher quality for both clients and contracts
It does a great job of connecting you with opportunities without your having to search through tons of projects like on other freelance sites. The projects are typically high quality, and Codementor ensures high-quality matches, so both sides don't have to deal with the lower quality projects and pay that plague other freelancing platforms. Caveats: You may need some reputation on the Codementor platform to be connected to good projects, and given the standard of quality, you may not see as many opportunities as on other sites. However, if your emphasis is on quality over quantity, CodementorX is a great platform.

Small Kinks, Great Potential, Strong Prospects
As a whole, I think CodementorX does a great job. It has taken a cut-throat industry of online freelancing and delivers a platform that I can feel comfortable using without trying to undersell my talents. Looking into the future, I think my main concerns would be how CodementorX can position itself so that it continues to deliver high quality content to both clients and freelancers. Platforms like Upwork and Toptal started off as decent solutions but ultimately end up where they are today. As a behavior interviewer and a CMX developer who likes to browse listings, it looks like there is already some saturation of ReactJS developers. If I was a ReactJS developer, it would feel a bit difficult to be picked if 15+ people have applied to a job posting. I don't readily have solutions to these concerns I raise but I am confident in CodementorX's future as a place where freelancers can go if they are serious about offering high quality services for a market-range price.
As a freelancer, I had a difficult client on a project who was both overly demanding and did not seem to know anything about his role as a CMX client. He did not seem to know how the billing system worked and the expectations set by CMX. This occurred with another client with whom I interviewed with. The client didn't know that he was supposed to fill out the survey and explicitly express intent to work with me. As someone who is new to CMX, it can be a bit confusing to balance figuring out the platform for yourself and the client.
There are a few platform issues that appear once you start using the CodementorX platform more. It doesn't always seem like the support channels (Contact Us) are the best way to address them since I have sent out e-mails per the instructions there and have not received a response. Here are a few:
1. US Social Security Number - this is displayed as plaintext to the user. I'm not sure if this is PCI data and needs to be encrypted but at least don't show it as plain text where anyone can look over my shoulder to see the last 4 digits.
2. SSO Accounts - I feel disadvantaged as a user who uses Google login versus making a CodementorX account. I can't use the app, my e-mail, etc.
