Tripcents wouldn't exist without Toptal. Toptal Projects enabled us to rapidly develop our foundation with a product manager, lead developer, and senior designer. In just over 60 days we went from concept to Alpha. The speed, knowledge, expertise, and flexibility is second to none. The Toptal team were as part of tripcents as any in-house team member of tripcents. They contributed and took ownership of the development just like everyone else. We will continue to use Toptal. As a start up, they are our secret weapon.

Brantley Pace, CEO & Co-Founder


I am more than pleased with our experience with Toptal. The professional I got to work with was on the phone with me within a couple of hours. I knew after discussing my project with him that he was the candidate I wanted. I hired him immediately and he wasted no time in getting to my project, even going the extra mile by adding some great design elements that enhanced our overall look.

Paul Fenley, Director

K Dunn & Associates

The developers I was paired with were incredible -- smart, driven, and responsive. It used to be hard to find quality engineers and consultants. Now it isn't.

Ryan Rockefeller, CEO


Toptal understood our project needs immediately. We were matched with an exceptional freelancer from Argentina who, from Day 1, immersed himself in our industry, blended seamlessly with our team, understood our vision, and produced top-notch results. Toptal makes connecting with superior developers and programmers very easy.

Jason Kulik, Co-Founder


As a small company with limited resources we can't afford to make expensive mistakes. Toptal provided us with an experienced programmer who was able to hit the ground running and begin contributing immediately. It has been a great experience and one we'd repeat again in a heartbeat.

Stuart Pocknee , Principal

Site Specific Software Solutions

We used Toptal to hire a developer with extensive Amazon Web Services experience. We interviewed four candidates, one of which turned out to be a great fit for our requirements. The process was quick and effective.

Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.

Dennis Baldwin, Chief Technologist and Co-Founder


Working with Marcin is a joy. He is competent, professional, flexible, and extremely quick to understand what is required and how to implement it.

André Fischer, CTO


We needed a expert engineer who could start on our project immediately. Simanas exceeded our expectations with his work. Not having to interview and chase down an expert developer was an excellent time-saver and made everyone feel more comfortable with our choice to switch platforms to utilize a more robust language. Toptal made the process easy and convenient. Toptal is now the first place we look for expert-level help.

Derek Minor, Senior VP of Web Development

Networld Media Group

Toptal's developers and architects have been both very professional and easy to work with. The solution they produced was fairly priced and top quality, reducing our time to launch. Thanks again, Toptal.

Jeremy Wessels, CEO


We had a great experience with Toptal. They paired us with the perfect developer for our application and made the process very easy. It was also easy to extend beyond the initial time frame, and we were able to keep the same contractor throughout our project. We definitely recommend Toptal for finding high quality talent quickly and seamlessly.

Ryan Morrissey, CTO

Applied Business Technologies, LLC

I'm incredibly impressed with Toptal. Our developer communicates with me every day, and is a very powerful coder. He's a true professional and his work is just excellent. 5 stars for Toptal.

Pietro Casoar, CEO

Ronin Play Pty Ltd

Working with Toptal has been a great experience. Prior to using them, I had spent quite some time interviewing other freelancers and wasn't finding what I needed. After engaging with Toptal, they matched me up with the perfect developer in a matter of days. The developer I'm working with not only delivers quality code, but he also makes suggestions on things that I hadn't thought of. It's clear to me that Amaury knows what he is doing. Highly recommended!

George Cheng, CEO

Bulavard, Inc.

As a Toptal qualified front-end developer, I also run my own consulting practice. When clients come to me for help filling key roles on their team, Toptal is the only place I feel comfortable recommending. Toptal's entire candidate pool is the best of the best. Toptal is the best value for money I've found in nearly half a decade of professional online work.

Ethan Brooks, CTO

Langlotz Patent & Trademark Works, Inc.

In Higgle's early days, we needed the best-in-class developers, at affordable rates, in a timely fashion. Toptal delivered!

Lara Aldag, CEO


Toptal makes finding a candidate extremely easy and gives you peace-of-mind that they have the skills to deliver. I would definitely recommend their services to anyone looking for highly-skilled developers.

Michael Gluckman, Data Manager


Toptal’s ability to rapidly match our project with the best developers was just superb. The developers have become part of our team, and I’m amazed at the level of professional commitment each of them has demonstrated. For those looking to work remotely with the best engineers, look no further than Toptal.

Laurent Alis, Founder


Toptal makes finding qualified engineers a breeze. We needed an experienced ASP.NET MVC architect to guide the development of our start-up app, and Toptal had three great candidates for us in less than a week. After making our selection, the engineer was online immediately and hit the ground running. It was so much faster and easier than having to discover and vet candidates ourselves.

Jeff Kelly, Co-Founder

Concerted Solutions

We needed some short-term work in Scala, and Toptal found us a great developer within 24 hours. This simply would not have been possible via any other platform.

Franco Arda, Co-Founder


Toptal offers a no-compromise solution to businesses undergoing rapid development and scale. Every engineer we've contracted through Toptal has quickly integrated into our team and held their work to the highest standard of quality while maintaining blazing development speed.

Seven Clear Signs That You're Ready to Hire a Node.js Consulting Specialist

Professional consultants know the importance of using the right tool for the job. Plus, they know which tool that actually is.

As your business or department grows, you will inevitably hit a point (over and over) where the people working for you cannot sustainably accomplish the tasks you set for them at the rate your plans require. When it comes to Node.js development, a significant factor in that situation can be the fallout of inefficiency that comes with not following best practices and a general lack of awareness of the Node.js paradigm and ecosystem.

Watch for these signs to know when you should hire a Node.js expert, before things have gotten stressful—if they haven't already.

Clear Sign No. 1: “Just Restart Node” Is Part of Your Weekly (Or Daily!) Parlance

If you restart your Node instance whenever something isn’t working, and you do this because this actually tends to fix things, that’s a problem. That isn’t going to fly when your Node app is in production. Plus, as your source tree grows and evolves, this will only get worse than when it was first built. If nobody on your team has been able to figure out why this is, it’s time to get outside help. Doubly so if everyone has become resigned enough to this job to stop thinking about it.

Clear Sign No. 2: “Reclone, Re-install, and Rebuild” Is Your Fallback Solution

Even more insidiously, if you find that you have to reclone your repo, run npm install, and build your project from scratch to get your project behaving properly again, it’s a problem. It may not cause you nearly the level of in-production headache as the previous sign, but it certainly indicates that your team could use a skill boost when it comes to Node projects.

The more fallback strategies you have that smell like this one, the more your development environment depends on unreliable black boxes and arcane magic.

You need someone to open these boxes up and shed light on them. If your own developers can’t depend on your project to behave consistently, your end-users will likely have a similar experience, if not worse. By not getting help, you’re forcing yourself to either admit that you have no idea what’s happening with one of your product’s core technologies, or worse, lie about it to them.

Better to just get proper help with your Node.js development!

Clear Sign No. 3: There’s Nobody Left Who Knows the Intentions behind Architecture-level Decisions

It’s normal nowadays for people to come and go from projects for all manner of reasons. Because of this, it’s not always easy to tell what level of quality you can expect to find in the code or design someone leaves behind. Worse yet, unless priority was given to planning and documentation, there may be important project decisions whose rationale are no longer part of your team’s knowledge pool.

The clearer you can be about your project's history and intentions, the easier it will be for a Node.js consulting specialist to do their job.

Sometimes, that’s OK. Other times, problems arise, and your team has to choose between staying with what was decided, or taking things in a new direction.

For example, maybe your original developer decided to use a particular database back-end, knowing how to scale it in a certain direction when the time came. That time is now. If your current team doesn’t know how to do that, they may not even know whether the scenario they are facing was planned for or overlooked. You may go off hiring a database specialist to solve the problem, when really, your data should be persisted with some other technology.

At this point, a Node.js specialist is still a generalist enough, and should have enough experience with different projects to be able to suss out the intentions (or lack thereof) of the original decisions on your project.

This time it might be good to get them to document their reasoning.

Clear Sign No. 4: The Main Debugging Tool Used by Your Team Is Still console.log()

Don’t get me wrong: It’s good to know how to use more basic tools in case you are ever stuck having to use them. But they should also give you an appreciation for more advanced tools, which you should then take advantage of where possible.

console.log() is like that. Great for learning Node.js programming, and perhaps for a one-off, quick-n-dirty debugging session. If its use has become habitual within your team, we predict that either your Node.js app has output that’s difficult to filter, or has so little output that anyone on your team who is debugging is constantly adding and removing console.log() statements ad-hoc. Not great.

A Node.js consulting specialist will know the benefits of using the debug module, which makes it easy to filter output by category, to tailor output to how you need it in the moment. They’ll also know that any IDE worth its salt will have a Node.js-compatible debugger, with all of the typical nice features like breakpoints, variable inspection, watches, and so on.

They’ll know that even if you don’t use such an IDE that it’s possible to use Node.js’ built-in command-line tools to accomplish the same thing, and how you can hook your app’s back-end up to Chrome/Chromium’s GUI debugger if you want to go that route instead.

It’s not just that debugging is overly tedious and inefficient with console.log(). Some classes of bugs are all but impossible to tease out without more sophisticated techniques.

For example, memory leaks may be occurring in your Node.js application without you even being aware of it. Your development runs of the Node.js back-end may be short enough or shielded enough from view that you haven’t had the chance to notice yet. In production, though, your clients certainly will, regardless of who is hosting the back-end.

Finding memory leaks.

Clear Sign No. 5: No One on Your Team Has Heard of Yarn

This is a pretty good sign that your team’s knowledge of the Node.js ecosystem and best practices has become outdated. That can be OK in some cases—maybe your main dependency versions are locked down, for whatever reason, so this happens to work for you. But new tools can offer enough substantial benefits that might have been previously lacking in your team’s workflow.

Yarn, an alternative package manager to the previously de facto npm, at the very least can boost your package install time with virtually no setup.

Maybe you don’t decide to use it in the end. That’s OK: It’s not for everyone. But its popularity in the Node.js space means that if nobody on your team has heard of it, your team could use some knowledge cross-pollination to stay sharp and effective.

Clear Sign No. 6: Your Team Is Unknowingly Developing on Different Versions of Node.js

Another very concrete sign you can check for is any discrepancy between your various team members’ output of node --version. First of all, this can easily be a source of WOMM (“Works on my machine!”) syndrome, as your app’s back-end behavior can be affected regardless of whether you tend to use cutting-edge features or not.

Second of all, a Node.js consulting specialist should not only coach your team on best practices, but also be fairly current with Node.js core changes. He or she would be much more likely to have such changes on their radar when your team is troubleshooting, and have a solid opinion on when to upgrade and when to work around bugs in Node.js itself, saving your team from pulling their hair out.

If you really need multiple Node.js versions installed, a Node.js expert would teach you how to use tools like nvm, as with yarn above.

Clear Sign No. 7: Your Back-end Team Has No Test Suite

If regressions are a common occurrence, or your team spends an undue amount of time manually testing features in a way that would be easy to automate, it’s time for a test suite. A Node.js specialist will know what it takes to set one up and also what sorts of processes are worth testing.

They’ll be able to work with Mocha or Jasmine—or whatever it is your team prefers—to get you the practical balance your team needs to make changes with confidence: the most prevention (every ounce of which is worth a pound of cure, remember) for the time invested writing the test suite in the first place.


Not everybody needs Node.js consulting for their team, but if you notice any of the signs in this article, it’s high time you gave it some serious consideration. Teams and projects grow and evolve with time, and some outside help from a Node.js expert can inject some life back into your project, helping improve your team’s tools and workflow. This, in turn, helps improve both the quality of your product and the quality of life for your team members. Everybody wins!
