How much does it cost to hire an offshore MongoDB developer?

MongoDB is an open-sourced database that uses a flexible way of storing data which makes it highly popular among developers around the world. It was created to replace MySQL as it is an easier way to work and collect data. The main advantage of this database is the way it stores and keeps data: instead of storing the data in a table of rows, it keeps files in BSON format, for apps to easier access and converts them to JSON files.

There are also some advantages of MongoDB:

• High-performance level and speed. Storing data in the RAM allows keeping the process fast.
• Flexibility. Having dynamic architecture allows working with non-structured data and adapting to a changeable business.
• User-friendly interface and quick setup. It is easy to install and set up. It also allows developers to use NoSQL structures.
• Horizontal scale-out. This type of scaling, unlike other SQL databases, increases storage capacity.

Companies and development teams can use MongoDB in many various ways.

• Integration of large amounts of data. If you need to integrate a large amount of data into the database, MongoDB can deal with it due to its flexibility and scalability.
• Description of data structures. This option means that the database allows describing structures and allowing data-name changes in generations of documents.
• Provision of data for high-performing applications. Unlike other databases, MongoDB is scalable enough to proceed with multiple data transactions in huge databases.
• Cloud applications support. MongoDB has many ways of configurations, so if you need to run the cloud application, you can rely on this database.
• Collaboration support. In document databases, each team can control different parts of the document, which increases collaboration.

Many companies and developers use MongoDB for several reasons:

• Deployment options. This database is available for almost every public cloud, such as AWS (Amazon Web Services), Google Cloud, and Azure.
• Document model. Developers can work faster as document model works well in storing data with any modern programming language.
• Scalability. MongoDB allows to store and keep huge amounts of data and traffic.
• Ability to start to code quickly. Developers who just installed it can begin to code right away.
• Large community. There is a large community worldwide with a mature ecosystem which makes it easy to get help.

MongoDB was created in 2007 by MongoDB Inc., which develops and provides support for NoSQL databases and MongoDB.

You can use the tools described below to ease the data storing and managing of the database.

• MongoDB Shell. It is an interface based on JavaScript for MongoDB. You can easily and quickly connect to MongoDB, update available data operating settings, and also perform administrative operations. MongoDB Shell has expanded the command-line interface–it is filled with syntax intelligent autocomplete, highlighting, and contextual help.
• MongoDB Compass. It is a powerful GUI that lets you easily manipulate, aggregate, analyze and quire your data in MongoDB. It provides detailed schema visualizations, great querying abilities, and even the option of real-time performance indicators measuring. This tool has three main versions: a full version, a read-only version, and an isolated edition.
• MongoDB Cloud CLI. You can manage your Cloud services, such as Atlas, Cloud Manager, and Ops Manager, by using the MongoDB CLI (Command Line Interface). You can test, script, and make other actions just by using the MongoDB Cloud CLI.
• MongoDB Data API. This tool helps to read, update, delete, and modify MongoDB Atlas data without using any additional drivers and libraries, and other connectional tools.
• MongoDB Command Line Database Tools. It is a collection of command-line tools which you can use with MongoDB deployment. As these tools are created apart from MongoDB, you can receive updates frequently with more useful updates.
• MongoDB BI Connector. MongoDB Connector for Business Intelligence (BI) allows users to create queries with SQL for graphing, reporting, and visualizing data from the MongoDB server.

MongoDB developer is a specialist in the IT field who develops and maintains applications and software using Mongo tools. It is essential for them to know the difference between the SQJ and NoSQL databases. They also should know the syntax of MongoDB. MongoDB is also widely used among backend developers and data analysts as it significantly easies their work.

• Junior MongoDB developer
  Junior MongoDB developers have from zero to two years of experience. They should have basic knowledge of Mongo development, knowledge of programming language, and little expertise in cloud computing and database architecture. Junior developers usually work in teams with more experienced developers. In such conditions, they learn from simple tasks, learn how to communicate with other teammates, and deal with set tasks.
• Middle MongoDB developer
  Unlike junior MongoDB developers, middle developers should have from 3 to 5 years of experience. They should have more advanced knowledge of Mongo development, more than one programming language, understand database architecture well, and be able to provide ideas and create high-quality software.
• Senior MongoDB developer
  Senior MongoDB developers should have a good experience level (from 5 years). This experience level requires advanced knowledge of databases, MongoDB, several programming languages, and potential limitations within MongoDB. They can also be the DBA (Database Administrator) as, during such time of working, they acquire the needed skills. Senior software engineers also manage junior developers and projects what requires them to have strong management and communication skills.

MongoDB developers often have the following responsibilities:

• Develop, configure and maintain MongoDB models.
• Write and run processes of backup and recovery.
• Keep documentation of databases and architecture clear.
• Design and develop new ways of indexing.
• Upgrade databases using patches.

MongoDB developers need to have a set of skills, which we will describe below.

• Experience with Big Data solutions, for example, Hadoop.
• Advanced knowledge of programming languages (Python–MongoDB has a native Python driver so these two could work together well; C++, Go, Java, and PHP).
• Experience in developing a system that works with huge amounts of data and transactions.
• Experience in full-stack development using MongoDB.
• Experience in architecting web applications and web portals.

If you need to hire a MongoDB developer, you have several options: freelancers, in-house developers, outsourced engineers. Here we will discuss these three types of programmers.

• Freelance MongoDB developers
  The first option you can find is a freelance MongoDB developer. These developers usually don’t belong to any company, which means they will leave as soon as the project ends. They are a good option for companies with a small budget or if the project is short-term. On the other hand, it may be a problem to find the developer with the best matching skills as many skilled developers already have interesting projects or they work in software development companies that can provide them with interesting projects and clients.
• In-house MongoDB developers
  If you need developers at the stage of core development, you should hire in-house developers. As they work in your company, they will be dedicated to the project and will provide ideas on how to improve and develop the product. Although the team of in-house engineers is highly dedicated and skilled, there are some drawbacks, such as high expenses on technologies, tools, bonuses, and extra spending.
• Outsourced MongoDB developers
  The third option you can choose is outsourced MongoDB developers. You can hire the with YouTeam outstaffing model, which provides you with top-notch full-time engineers. Outsourced developers are a good option if you need to hire extra specialists for your in-house development team or get an independent development team (you can hire not only the team but also a product manager who will help the development team to easily integrate into your company).

You need to tell in detail about the company, what project you want to do and how it will contribute to the business, in general, to attract the developers with an interesting project. It is also important to describe all the requirements for the developer to get the best matching candidates. You should point out the next things to write a good MongoDB job opening:

• Point out the job title and the list of tech and soft skills requirements.
• Write your expectations about the project.
• Describe shortly your company and the field you work in (it will help developers who have some expertise in your industry to find the best solution).
• Write about the development stage (it may be either the development from scratch or maintenance work).
• List responsibilities the developer will have and describe the team.

If you need to test the candidate’s skills during the interview, you can ask them some of the following questions:

• What are some of the advantages of MongoDB?
• What is a Collection in MongoDB?
• How does Scale-Out occur in MongoDB?
• How to perform queries in MongoDB?
• What are the data types in MongoDB?
• What are Geospatial Indexes in MongoDB?
• What is the Aggregation Framework in MongoDB?
