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!

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.Â
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.Â
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.Â
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.Â
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.Â
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.Â
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.
