    The Review
    Feedback summary: 

    Hello World is professional, yet free of the rigid structure of many large development firms. They ask good questions in order to really understand the project but are capable of making their own judgment calls and working without undue oversight. The team has strong quality assurance measures.

    A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.


    Introduce your business and what you do there.

    CodeFuse Technology offers all types of tech services to our clients via a SaaS-based cloud platform. I’m the CEO.


    What challenge were you trying to address with Hello World?

    We were struggling for extra resources at the time. We had a number features we wanted to implement and we were looking to augment our existing development team with outsourced developers.


    What was the scope of their involvement?

    We had a series of features that we wanted them to deliver. As a part of our platform, what we wanted was that clients to be able to do is tag tests. Hello World had a voice in how we were going to implement the tagging mechanism. We got a test screen of how the user can do the tagging and then go across to a test scheduling screen where they can schedule those tests based on the tags they select. We sent over a story based feature with some acceptance criteria. We left a lot of the user-experience side up to Hello World and they just ran with it. They asked relevant questions when necessary and everything seemed to go fairly smoothly.

    How many resources have been assigned to your project?

    We’ve had two developers working with us at various times. There is a senior developer and a junior developer who come on board about half way through the last project. From a senior-to-junior point of view, we settled on a process of any junior development would be reviewed by the senior developer. That seemed to work quite well. It was a small team that we were using, but it seemed to work quite well with that senior/junior relationship and us coming across with as detailed requirements as we could.

    What technologies did they use on your project?

    Although our platform expands a little bit beyond this, the core technologies they were using were .NET and C#. There was also some SQL Server. The thing that restricted them a bit in terms of using C# and SQL Server was that our platform is Microsoft Azure based, so there has to be quite a lot of consideration given to the certain SQL that is supported by Microsoft Azure. There had to be a blended skill set of C#, .NET, SQL Server, and Microsoft Azure.

    How did you come to work with Hello World?

    We found them originally through the Upwork platform. What stood out to us wasn’t necessarily technical skill sets. It was more that we find what we’re looking for, not just developers, but marketing augmentation as well. It is more about do they demonstrate, do they understand the problem, can they break it down into small components? Can they provide value around implementations, suggestions, and how long the project might take? A lot of it is just ensuring that any contractor or freelancer that we use has to understand the problem. Hello World showed that to us through the interview process.

    How much have you invested with Hello World?

    We are paying the junior developer $25 per hour now. The senior developer was a bit more expensive than that. I’m guessing it averaged out at $30 per hour.

    What is the status of this engagement?

    We started working with them in September 2016. At the moment, the senior developer isn’t engaged with us, because the major features that we were asking for have been completed. We are using the junior developer for ongoing bug fixes and support.


    Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

    I think that they strike a nice balance between the freelancers that we’ve used for software development. It can get very bureaucratic. You can get things down into too much detail and too much process. On the other end of the scale, it’s almost a bit too loose. There is a broad sort of spectrum of how people approach their work. I think Hello World struck a nice balance between understanding a problem, asking questions when necessary, not interrupting our business too much with silly questions but asking questions at the right time. Obviously, if there is a big question, you want people to ask, but you don’t want to have your time wasted with silly questions where it should be just common sense. It was good working with them from that perspective. It minimized hassle for us, but we still got a good quality outcome at the end of it. For each feature, there was a set of questions to begin with which tended to be quite important questions about the implementation. Then after that, we had sort of regular check-ins from them every day or every other day so we could see the progress coming along. That all seemed to work quite well.

    There was just a good level of trust that the job was being done well. We would do code reviews internally, and they were doing code reviews between junior and senior developers. Overall, we were very happy with the overall management of each project and it was done without too much undue hassle for us.

    What did you find most impressive about Hello World?

    I think it was the speed of understanding complex problems. Our platform has been in existence for four or five years. There has been a lot of different work done on it and some of it is pretty complicated. But generally, the developers got into a piece of code and understood things quite rapidly. Some of the things we struggled with internally, Hello World could understand very quickly. There was very little unproductive time analyzing legacy code.

    Are there any areas Hello World could improve?

    We have worked with a plethora of different freelancers where the quality has been up and down. Generally speaking, we have been pretty happy with the quality, communication, etc. from Hello World. Nothing really springs to mind. I don’t think that I really have any mess-ups or anything like that.
