      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      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.

The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

      WordPress Website Design Review from Clea Bierman

      Blue Meridian Partners has worked with Constructive as our website design and development partner for more than eight years. During that time, they have played a significant role in shaping our digital presence and helping bring our brand to life online. What I've appreciated most is Constructive's ability to balance creativity with stewardship. They have consistently found thoughtful ways to push our brand forward when innovation was needed, while also respecting and working intelligently within established brand guidelines. Their team understands how to translate complex ideas into engaging digital experiences. Across dozens of projects, I've worked with three different project managers, and each has been highly accountable and genuinely enjoyable to partner with. The relationships have been professional, collaborative, and built on trust. We've also had several occasions where creative projects required significant work on very tight timelines with little notice, and Constructive consistently found a way to deliver. Like any long-term partnership, navigating complex websites and evolving organizational needs requires ongoing communication and attention. What has kept us coming back year after year is Constructive's commitment to partnership, their willingness to solve problems alongside us, and the care they bring to our mission. I am grateful for their contributions to Blue Meridian's growth and would confidently recommend Constructive to organizations looking for a thoughtful, mission-driven digital agency.

      Nonprofits Review from Robert Espinoza

      Constructive built PHIs website back in 2017-2018 and, in many ways, they have been with the organization ever since. Over almost eight years, they've grown alongside PHI rather than simply maintaining a site. PHI is a national nonprofit working at the intersection of research, policy, and workforce interventions on the direct care workforce, and a lot of what we do is complicated. Constructive's remarkable team has had a real knack for turning that complexity into something clear, usable, and genuinely engaging online. Some of the things I'm most proud of from our partnership like our worker story gallery, our national resource center on direct care workers, and our online index came out of that collaboration. These weren't just features; they became core parts of how we tell our story and share our work with advocates, policymakers, and practitioners. What made Constructive stand out was how invested they were in our mission. They were creative and technically excellent, yes but more than that, they showed up as a true partner. We didn't experience them as a vendor so much as an extension of our team. I would absolutely recommend them to any nonprofit or social impact organization looking for a thoughtful, dependable digital partner.

      Nonprofits Review from Diana Denza, MPA

      The Center for Family Representation worked with Constructive on a year-long rebranding process that overhauled our logo, colors, website, and all of our marketing collateral. As a result of this process, we now have a brand that truly represents our organization and the work we do for low-income NYC families. Constructive was highly responsive and professional throughout the process, working with us to ensure that every element of the rebranding felt just right.

      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.

      I am thoroughly pleased with your companies ability to deliver an exceptional working relationship that has lead to an eloquently executed client experience. Isadora Digital Agency took a much-needed concierge approach to our relationship and helped us define our goals as well as align the expectations of the officers of our company. Our needs and vision were sophisticated but you helped us to achieve our vision through a multitude of legal and compliance challenges while still creating a warm and textured environment for our clients to engage with us. There have been multiple occasions the agency has gone exceptionally above and beyond to make this project a success – had we partnered with some of the other 9 design companies we were engaged with, I don’t feel confident that they would have provided the white glove service that we received from your firm. Let me summarize: Isadora delivers enterprise style service and results with the client engagement and human interaction of a boutique firm.

      Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen.

      I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.

      Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!

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  Properties Commonly used frameworks/Used for
Python One of the most widely used languages for backend services, data platforms, and AI-powered applications. 
  • Django
  • FastAPI
  • Flask 
Java One of the most widely used languages for enterprise backend systems, particularly in industries like finance, healthcare, and large SaaS platforms.
  • Spring Boot 
JavaScript/Node.js JavaScript is traditionally associated with frontend development. 
  • Used for backend development through Node.js
C#/.NET Key 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 
PHP Widely 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.

Project Timeline Backend scope
Startup MVP backend platform 2-6 months Core APIs, authentication, database setup, basic integrations, and initial cloud deployment 
Mid-scale SaaS or web platform 6-9 months Scalable APIs, advanced business logic, database optimization, multiple integrations, and monitoring systems 
Enterprise backend systems 9-12 months Distributed services, high-volume data processing, compliance features, complex integrations, and infrastructure automation
Large platforms with complex infrastructure 12-18+ months Microservices architecture, real-time processing pipelines, global cloud infrastructure, and large-scale databases
