Customers love TurnKey (and we love them back!)

3 Years in a Row Best in KLAS for Ambulatory Revenue Cycle Management (RCM) Services

"TurnKey is the only offshore firm we've interacted with that really places an emphasis on retention. They seem to be the only ones that understand how important retention is to maintaining strong product development cycles. Our churn rate with TurnKey has been under 5% annually whereas we were at more than 50% with our previous vendor!"

We've hired 5 full-time software engineers through TurnKey. To date, not a single engineer has left our contract/arrangement. We worked with several U.S.-based recruitment firms, and none matched the speed and quality of candidates referred by TurnKey. Most impressive and unique about TurnKey is their willingness to reach for the perfect candidate. Our requirements are strict, and they did not compromise.

"It's been nearly two years of us working together and we have not had the need to replace a single developer. The programmers have all performed very well and TurnKey has been able to give us information that has helped to retain our key players."


Mackezie Drazan (US)

CEO of MiResource

We have hired 5 total developers including tech lead, full stack, dev ops and firmware. For each hire, a strong pipeline of candidates was provided, and the TurnKey team performed a lot of pre-screening such that those that entered the funnel were strong and relevant. They also helped with setting salary comp, and closing. Finally they continue to provide HR services as well as legal admin services associated with employment of a geographically diverse group of developers.

We started with 8 hired developers and there have been no problems with any of the hires. We are currently monitoring them as we do all engineers but there is nothing to report that would make us consider this arrangement with TurnKey anything but successful. The transparent pricing up front as well as the genuine desire to continue improving with each hire we make is a big difference maker for us.

TurnKey provided high-quality talent at a cost-effective price. We employed TurnKey to manage the hiring/HR/Legal for >80% of our entire Product team - from identifying and hiring Team Leads, to agent level support roles. I also appreciated that they were proactive in suggesting certain criteria and requirements when first starting our search for key team lead members.

The Best E-Signature Software According to G2

We reviewed several similar companies and along with the cost the major deciding factor was the quality of experienced candidates TurnKey was presenting to us. The additional team members worked alongside our scrum teams delivering new feature functionality and enhancements to our platform.We're impressed with the quality of their candidates and the work ethic they demonstrate on a day-to-day basis in our agile ceremonies.


Sandy Speirs (US)

Director Of Engineering at Sertifi, Inc.

TurnKey is well versed in the startup ecosystem and really understands our needs when it comes to offshore dev, particularly how our needs may be different than the needs of a huge public company. I don’t have to explain as much to TurnKey as I have had to do with other offshore vendors—they seem to get it on the first take. But at the end of the day, all we really care about is quality, and TurnKey has delivered the goods on this front better than other firms we’ve worked with in the past.

Key Questions – and Answers! – about JavaScript developers


Why is JavaScript popular?

JavaScript is popular because it is widely used in web development and has a strong community of developers who contribute to its development. Additionally, it is easy to learn and use, and can be used for both front-end and back-end development. JavaScript frameworks, such as React, Angular, Vue.js, and Node.js, enable developers to build complex web applications that are scalable, secure, and high-performance. With the advent of modern front-end frameworks like React Native and Electron, developers can also create mobile and desktop applications using JavaScript.

How to hire an JavaScript developer?

To hire a JavaScript developer, businesses should define job requirements clearly and post job ads on relevant platforms such as LinkedIn or Indeed. They should conduct technical interviews to assess the candidate's knowledge of JavaScript frameworks, understanding of database management systems, problem-solving skills, and communication skills. It is also essential to evaluate candidates based on their soft skills such as teamwork, collaboration, and communication. Candidates with experience in working with popular JavaScript frameworks and libraries, creating web applications from scratch, and implementing responsive design principles should be prioritized.

You can simplify the process by using our staff augmentation services.  We take a proactive approach to address the hiring challenge by implementing comprehensive, multi-tiered recruiting services.

These developers should also possess soft skills such as communication, collaboration, adaptability, and creativity, as these are critical for delivering high-quality solutions. In addition, they should be familiar with the latest front-end and back-end technologies, such as HTML5, CSS3, jQuery, React, Node.js, and more.

Top interview questions to hire JavaScript developers

The main interview questions to hire JavaScript developers should assess their knowledge of JavaScript frameworks and libraries, understanding of database management systems, problem-solving skills, and communication skills. Some potential questions include:


  • Can you explain the difference between React and Angular? Which one would you prefer to use for a particular project and why?
  • Have you worked with any popular JavaScript libraries like jQuery or Underscore.js? Can you share some examples of how you've used them in your projects?
  • How do you manage database connections and transactions in JavaScript? Can you explain the difference between SQL and NoSQL databases? Have you worked with any of them?
  • Can you walk me through how you would approach solving a complex programming problem using JavaScript? How do you handle errors and exceptions in your JavaScript code? Can you provide an example?
  • How do you collaborate with other developers when working on a project? Can you give an example of working in a team?

What are the tools used by JavaScript developers?

JavaScript developers use a variety of tools to build web applications. Some popular tools include:

  • Code editors such as Visual Studio Code, Sublime Text, and Atom
  • Version control systems like Git and SVN
  • Task runners and build tools like Gulp, Grunt, and Webpack
  • Debugging tools like Chrome DevTools, Firefox Developer Edition, and Safari Web Inspector
