How to Become a Freelance SQL Developer

If you have a knack for working in an environment that deals with storing and accessing business information you may have what it takes to become a freelance SQL developer.

SQL stands for Structured Query Language and is an ideal method for communicating with a database. A domain-specific language, SQL is used for managing data contained in a relational database management system.

What does a freelance SQL developer do?

A freelance SQL developer has the responsibility of programming design tables, writing queries, and ensuring those queries perform at required speeds. Many SQL developers are experts in database development or are database administrators.

There are different SQL types or versions, including MySQL, SQLite, PostgreSQL and SQL Server. While your client may require your expertise for one or more SQL types you’ll be asked to perform the same basic functions that involve retrieving, adding, editing, and deleting database data.

As a freelance SQL developer, you should be adept at working and problem-solving in all SQL areas. This may mean brushing up on some programming languages, but when you start getting clients, you’ll add some valuable work experience to your resume.

What skills do I need to become a freelance SQL developer?

Although there are different versions of SQL, there are key skills developers should possess in order to effectively provide value to clients.

Common skills that may be listed on as a freelance SQL programming job description template may include:

  • Microsoft SQL: Microsoft has its own SQL server designed to store and retrieve data from various applications. Freelance SQL developers should be familiar with Microsoft SQL because many organizations use it to store and retrieve data.
  • Database management skills: Creating backups for data is a key requirement for many clients needing the services of a SQL database specialist. You’ll also need to be adept at troubleshooting database systems and debugging where needed.
  • Application Development and Execution: Developing a query that will execute according to your client’s requirements is essential to getting the most out of SQL.
  • Familiarity with indexing: Indexes indicate how quickly a query can be executed. Freelance SQL developers must ensure indexes operate correctly. You’ll also need to analyze data quality.
  • Data analysis capability: SQL allows marketers and other professionals who rely heavily on data to identify and understand the behaviors and trends of their target audience. Being up to date on the latest methodologies of data management and data modeling.
  • Communication skills: It’s important that freelance SQL developers work with software engineers, software developers/programmers, and other team members while navigating database programs. To help ensure collaboration success, exhibiting good verbal and written communication skills is a must.
  • Problem-Solving Skills: Working with SQL programming languages and data may not always be smooth sailing. Being able to troubleshoot problems in different database systems is definitely a plus.

What are the core freelance SQL developer job responsibilities?

With multiple versions of SQL and varying client requirements, it's possible freelancers will handle different types of assignments. But there are still core duties most clients will ask their freelance SQL developer to handle.

A list of responsibilities clients will ask freelance SQL developers to handle include:

  • Building client data integrations with automated queries to provide insights into the real estate market
  • Collaborate with business analysts and marketing teams to develop requirements for database queries based on business intelligence
  • Being a team player and working with the Quality Assurance team to ensure development goals are regularly met
  • Building an automated report distribution solution that informs senior management as new data is entered into database programs.
  • Instruct teams on using Microsoft SQL server
  • Help troubleshoot problems associated with newly developed database SQL queries.

Should I get a degree or certification to become a freelance SQL developer?

Some examples of popular degrees or certifications that are helpful for budding freelance SQL developers include:

  • An associate, bachelor’s degree, or master’s degree in computer science, management information systems, information technology, or an equivalent field of study from an accredited college or university
  • Microsoft Certified Technology Specialist (MCTS) – offered by Microsoft
  • Oracle Database PL/SQL Developer Certified Professional – offered by Oracle
