      Software Development Review from Claus-Peter Mueller

      We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

      WooCommerce Review from Amanda Viviano

      We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

      Web Development Review from Sanjay Singh

      I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

      Shopify Review from Sarah Nesheim

      Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

      Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have.Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart.Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.

      Onco has been a client of CMDS for several years and we find that their marketing and SEO knowledge is very valuable. All of the staff we interact with have been willing to take the time to understand our unique business and how we should present our strengths to prospective clients. They never take a cookie cutter approach and instead have been able to help us voice our message clearly and concisely. I would recommend them to any business owner looking for a fresh approach to graphic design and marketing with a unique ability to maximize the benefit of social media campaigns.

5 Frequently Asked Questions About US Backend Development Companies

Which programming languages are most used by backend developers in the United States?

Backend development in the United States relies on several mature programming languages that support scalable APIs, cloud infrastructure, enterprise systems, and data-driven applications. 

Language PropertiesCommonly used frameworks/Used for
PythonOne of the most widely used languages for backend services, data platforms, and AI-powered applications. 
  • Django
  • FastAPI
  • Flask 
JavaOne of the most widely used languages for enterprise backend systems, particularly in industries like finance, healthcare, and large SaaS platforms.
  • Spring Boot 
JavaScript/Node.jsJavaScript is traditionally associated with frontend development. 
  • Used for backend development through Node.js
C#/.NETKey backend language in the U.S., especially for companies building enterprise applications on Microsoft technologies.
  • Enterprise platforms
  • Internal business systems
  • Cloud services on Azure
  • Enterprise APIs 
PHPWidely used by PHP developers building web platforms, content management systems, and eCommerce backends. 
  • Laravel 
  • Symfony 

The GitHub Octoverse 2024 report found that Python became the most used programming language on GitHub, overtaking JavaScript after more than a decade at the top.

According to recent hiring data, about 39.5% of recruiters are actively seeking a Java developer for their teams, making it one of the most in-demand skills in software development hiring.

The Stack Overflow Developer Survey 2025, which collected responses from tens of thousands of developers worldwide, reported that about 66% of developers use JavaScript, making it the most commonly used programming language overall. 

What do US backend development companies do?

They design, build, and maintain the server-side systems that power modern digital products. The systems handle the logic, data processing, and infrastructure behind applications such as SaaS platforms, eCommerce websites, mobile apps, and enterprise software.

  • Build and maintain server-side application logic: Writing the server-side code that powers applications, processes requests from users, executes business logic, and returns results to the interface. 
  • Design databases and manage application data: Creating and maintaining databases that store user accounts, product information, transactions, and analytics data. A backend engineer designs schemas, optimizes queries, and ensures fast data retrieval from systems such as SQL or NoSQL databases. 
  • Develop Application Programming Interfaces (APIs) and integrations: Building APIs that allow different systems to communicate. APIs connect web applications with mobile apps, payment gateways, cloud services, and third-party platforms.
  • Build scalable cloud infrastructure: Building infrastructure that can support millions of users and large volumes of data, including cloud architecture, containerized services, microservices platforms, and automated deployment pipelines. 
  • Support security, performance, and reliability: Protecting data and ensuring applications run smoothly through authentication and access control, data encryption and security compliance, monitoring and error handling, and performance optimization.
  • Build and maintain complex software platforms: Building the core infrastructure behind SaaS platforms, fintech and payment systems, healthcare applications, enterprise business software, and eCommerce platforms. 

When should a company hire a senior backend engineer or a staff backend engineer?

Businesses usually hire a senior backend engineer or staff backend engineer when their software systems become complex enough that architecture, scalability, and technical leadership matter more than simply writing code. 

At that stage, experienced engineers help companies avoid costly technical mistakes and build systems that can scale reliably.

Businesses typically start needing staff backend engineers once their team expands to 50 or more engineers or when existing architecture cannot support growth in users or product features.

Hire a backend engineer when your:

  • The platform needs to scale to thousands or millions of users
  • The engineering team begins to grow
  • System architecture becomes a business bottleneck
  • Backend systems require advanced performance optimization

Modern backend systems increasingly rely on microservices, cloud infrastructure, and container platforms. In fact, about 75% of backend roles now require proficiency with cloud platforms such as AWS, Azure, or Google Cloud, reflecting the critical role scalable infrastructure plays.

How much does it cost to hire backend developers in the United States?

The cost of working with a backend development company in the USA varies widely depending on the project scope, the engineer's seniority, and the complexity of the software system being built.

Market benchmarks suggest the following rates:

  • Mid-level back-end developers: about $120-$160 per hour
  • Senior full-stack or backend engineers: around $130-$190 per hour
  • High-end enterprise engineering services: $300-$800 per hour for specialized projects and large consulting firms.

The mentioned rates are significantly higher than internal salaries because United States backend development companies also include project management, QA testing, DevOps, and infrastructure support within their pricing models.

Project pricing depends heavily on system complexity. Typical backend development budgets in the US market include:

  • Small backend service or MVP: $20,00-$80,000
  • SaaS platform backend: $80,000-$250,000
  • Enterprise or large-scale platform: $250,000-$1,000,000+

How long does a backend development project usually take?

The timeline for a backend development project depends on the platform's complexity, the number of required integrations, and the size of the engineering team. 

Some backend systems require up to 800 hours of backend development work for core infrastructure alone, depending on the number of APIs, integrations, and database features implemented.

ProjectTimelineBackend scope
Startup MVP backend platform2-6 monthsCore APIs, authentication, database setup, basic integrations, and initial cloud deployment 
Mid-scale SaaS or web platform6-9 monthsScalable APIs, advanced business logic, database optimization, multiple integrations, and monitoring systems 
Enterprise backend systems9-12 monthsDistributed services, high-volume data processing, compliance features, complex integrations, and infrastructure automation
