Frequently Asked Questions
Are you an Agency?
Well, some clients call us a virtual agency or an agency 2.0 :)
1. Typical agencies take 50-70% from a developer salary. We take only 15-30%.
2. Agencies have 10-20 developers on their bench (available). We’ve got 300+ devs.
3. Agencies don’t allow developer buy-out. You can hire our developer in-house after 1 year for “1-month salary” fee.
Will I have a contract with a developer or with Expert Remote?
With Expert Remote.
It’s risky to have 5 contracts with 5 remote developers from 5 different countries.
You’ll have a single B2B contract with our company. So, if smth goes wrong with IP or anything, you can always sue us :)
P.S. Our company is registered in the USA and Poland.
How does the pricing work?
Each developer has their own hourly rate with our commission already included.
We take between 15% and 30% from what you pay, which is 2-3x lower than typical agency fees.
No setup fees. You only pay after you hire a developer.
2-week paid trial. If you don’t like our developer after 2 weeks, we’ll apply a 25% discount on the hours worked.
1-week notice. You can ask for a replacement or cancel the contract within a week.

What are your average rates?
Rates start from $20/h. The median average is $35-40/h.
There’s always top 10% percentile candidates who are overpriced, and bottom 10% percentile underpriced ;) But most fall into the market rate category.
The beauty of global sourcing is tapping into unknown regions. Have you heard of North Macedonia? You can find senior developers for $25/h (our fee included)!
How do you ensure developer quality?
We source developers with marketing, which is 20-30x more effective than Linkedin. This creates us a huge flood of candidates.
Then we take this top of the funnel and feed it into our proprietary vetting process. Only top 1% of candidates make it through.
Part of the process is automated, which allows us to do it at scale. For instance, our recruiters have their calendars fully booked and able to conduct 200-250 soft-skill interviews a month.

Freelance Database Developer & Programmer for Hire
A database developer is a broad term that encompasses many different types of professionals. A database specialist is a professional who designs, organizes, sets up, and connects databases to the products they support. The most common database technologies used today are relational database management systems (RDBMS) like Oracle Database and MySQL.
You can hire database developers on a freelance basis for short or long-term projects. Let’s look at the different types of developers, their skills, and ways to hire database developers so that they bring real impact to your project.
Main Skills a Database Programmer Should Have
Freelance database developers and programmers are in high demand. If you’re looking to hire a freelance database developer, you should know what skills they need to possess to be considered professionals.
Relational (SQL) and Non-relational (NoSQL) Databases
These are two types of databases that store information based on different principles but ultimately serve similar purposes. Relational databases store data in tables (rows and columns), whereas non-relational databases do not have any concept of tables or rows. Instead, they collect and organize various types of data in a data structure.
SQL databases work great with static data that does not need to be altered after it is recorded. NoSQL types are better for more dynamic data flow.
The most common RDBMS is MySQL, which powers most enterprise systems including Uber, Airbnb, and Shopify. The most common non-relational database management system (NRDBMS) is MongoDB, which is used by Toyota, Forbes, and Flobiz.
A database developer is often responsible for the quality of the data that is being stored in the database. It means that they need to ensure that their code is working properly and that there aren’t any bugs.
Database programmers should know how to perform ACID properties validation, test data mapping, verify data integrity, and check business rule conformity.
CRUD Operation Knowledge
CRUD stands for Create, Read, Update, and Delete. Essentially, these are the basic visual operations you need to know if you want to work with databases in any capacity. When working with REST APIs, it’s important to understand the CRUD concept because it will help the developer comprehend how the application interacts with other systems.
A database developer must be able to model data in a way that is logical and practical. It means that they need to understand what the data will be used for and how it will be used. They must also keep in mind how data can be stored and retrieved from the database, as well as how quickly it can be accessed.
Software architecture defines how the software will be structured, what it will accomplish, and how it will be implemented. Database modules are parts of software architecture and are reflected in a database. Each module represents a separate collection of files or data structures that perform specific functions within the overall system. Database modules can be either physical or logical.
This is critical for database experts because it defines the way that data is stored in the database and what types of queries can be run on that data.
Backend Development Skills
A database developer needs to be able to manipulate the data. This means telling a database what to do with the data so that it can serve as a source of useful information. And though it’s not necessary to know C#, Java, or Python for database application development, even some basics can help enormously. It is especially relevant if the project is centered around handling a large amount of data.
What Freelance Database Developers to Hire for Your Project
Database development jobs are available across various domains such as healthcare and insurance, finance, e-commerce, and the education sector. Database experts can be categorized according to their specialization.
Hire database developer who has professional experience working with MySQL databases. They’ll be able to work with any type of SQL-based database system and help design an efficient schema that meets your technical needs.
When to hire MySQL database developers
MySQL is great for building small web solutions, like ecommerce stores for the local market. It is also a great choice for online analytical processing and online transaction solutions. In general, when a comparably small amount of data is used, MySQL will be a great fit.
Oracle is another popular database system, and it’s used by many large companies around the world for their mission-critical databases. Oracle developers can help your team design, develop and maintain an enterprise-grade database solution with a high level of availability.
When to hire Oracle developers:
If you have a large database to manage, then Oracle developers are your best choice. Oracle is a reasonable solution for data warehousing and online transaction solutions.
For smaller projects that require less expertise in MySQL or Oracle servers, but still need some complexity in their schemas, consider hiring MongoDB developers. They specialize in NoSQL systems, and their knowledge is more limited than those who’ve worked with more common systems. However, they can provide enough versatility when working with the MongoDB framework.
When to hire MongoDB developers:
Due to its NoSQL nature, MongoDB is best for real-time scalability and data integration. It will be a good fit for product catalogs with multiple attributes, or analytics platforms that continuously track information.
Cassandra database developers are great for business applications that need data to be available and consistent at all times. It’s also very good for workloads that are write-intensive and can handle numerous requests at once. However, if you need transactions in your app (e.g. creating users), Cassandra won’t work well because it doesn’t have ACID compliance like other databases do. The ongoing maintenance cost for a Cassandra database is also very low.
When to hire Cassandra developers:
Cassandra is a popular choice for user activity tracking, where it’s important to keep all data up-to-date as quickly as possible. It will be a good fit for data centers, weather apps, ecommerce stores — where there is a constant flow of information.
When you have a new project, and you are not sure which technology to use — hiring a Firebase developer will save you time and money. Firebase is beginner-friendly and easy to use while providing convenient access to data.
When to hire Firebase developers:
Firebase database developers are a common choice for real-time apps that need to be able to handle large amounts of data. Firebase is also easy to set up and can be used in conjunction with other databases like Cassandra. Cloud Firestore can process 1 million concurrent connections making it a good solution for apps with limited sorting and filtering queries.
Top Freelance Database Developer: Skillset by Level
Hiring a freelance database developer can be a daunting task, especially if you’re new to the field. If you’re hoping to hire database developers, here are some of the skillsets database experts should have at different levels.
Junior Database Programmer
Junior database developers are entry-level developers who have just started working with databases. The main skill they should possess is the ability to learn quickly, and if they are passionate enough, then you can expect them to grow fast. They also need to have logical thinking skills and technical skills. These two traits will come in handy while solving complex problems or identifying flaws in existing systems.
