Database developers play an essential role in managing large amounts of data, making it challenging for non-technical hiring managers and recruiters to find the right team. Belitsoft will guide you through creating an effective job description, interviewing, and evaluating skills to ensure you hire professionals who perfectly fit your project needs.
Hire Database Developers for Development, Migration or Modernization
Database developers play a key role in various stages of database management, such as database development, modernization, and migration.
Database specialists develop new databases from scratch to meet your organization's specific needs. They define table structures, write stored procedures, and establish security measures. Database engineers work in collaboration with software development teams to ensure that the application's logic, user interface, and data storage components are seamlessly integrated.
Developers modernize legacy database systems to align them with current technologies and make them more efficient. They upgrade to newer database engines, implement advanced security features like firewalls and encryption, and optimize existing queries for better performance. They also monitor key performance indicators such as transaction volume and response times.
Developers ensure a smooth transition when moving your database to a new environment or different system, without data loss or downtime. They handle data transfer, update application connection strings, and maintain data integrity. Tools like AWS Database Migration Service or Azure Database Migration Service are often used. After migrating to a new system, further development may be needed to fully utilize the new environment's features, such as automated scaling.

Database In a Nutshell
Databases are systems that store, organize, and manage data to facilitate the efficient retrieval of information. On a website, databases refer to the underlying technology used to manage and store site data. This concise guide offers an overview of how databases work, key terminologies, a comparison between SQL and NoSQL, and guidance on selecting the best database for your web application.
Businesses often require different types of databases for various purposes. Some common types to consider include centralized, cloud, commercial, distributed, end-user, graph, NoSQL, object-oriented, open-source, operational, personal, and relational databases.
- Scalability to consider how much your data is likely to grow and how quickly.
- Sharding in order to store vast databases across multiple servers and minimize response times for queries.
- Replication to ensure that the information is available and accurate with data updates or a crash.
- Latency to evaluate the time it takes for data to travel back and forth between the database server and the application server.
- Consistency to prevent errors in the database and ensure that any modifications to the database don't make it invalid.
- Availability to respond quickly to a request even if failures occur, which is important when using databases that are spread across multiple servers.
- Fault-tolerance to keep functioning even if one or more components fail, thanks to various techniques such as replication or redundancy.
When should you hire a database programmer?
In some organizations, developers manage databases. However, it's important to consider certain factors to determine if it’s necessary to hire a database developer.
Downtimes affecting business-critical apps
Prolonged periods of downtime are no longer acceptable in our always-connected world. So it's crucial to monitor for recovery and availability regularly after any downtime to ensure database accessibility. Businesses that depend on data availability until the last microsecond, like banks, financial companies, stock market apps, and emergency medical services, must take extra precautions. These services cannot afford downtime, delays, or transaction losses. In such cases, hiring database developers is essential for maintaining data security, reliability, and availability.
Latency issues leading to poor performance
Performance issues can be a telltale sign that a database developer is required. These issues can directly impact the user experience and can significantly affect both the commercial and brand image of an organization.
If your application is facing latency issues, many variables can play a role. Factors include poorly written applications, hardware and infrastructure limits, but most often, poor database optimization is the major cause.
Sophisticated hacking attacks
With the evolving challenges and sophistication of hacking tools and attacks, the field of security is constantly changing. Ensuring security and data availability are crucial factors that should not be overlooked and require specialized knowledge and continuous monitoring.
Rapidly increasing data impeding business scaling
If you have a high volume of transactions, you need to delete, modify, or rebuild the corresponding index frequently. As data and transactions grow, database log files expand. These log files are essential to ensure transactional consistency, deadlock resolution, and rollback. As the log file size increases, the response time for each transaction decreases.
