Career opportunities
You can choose from a wide variety of careers, few are discussed below:
Data Analyst
Data analysts are responsible for various tasks, including visualization, munging, and processing massive amounts of data. They also have to perform queries on the databases from time to time. One essential skill of a data analyst is optimization. This is because they have to create and modify algorithms that one can use to cull information from some of the most extensive databases without corrupting the data.
SQL, R, SAS, Python are some of the sought-after technologies for data analysis. So, certification in these can easily give a boost to your job applications. You should also have good problem-solving qualities.
Data Engineers
Data engineers build and test scalable Big Data ecosystems for businesses to run their algorithms on data systems that are stable and highly optimized. They also update the existing systems with newer or upgraded versions of the current technologies to improve the efficiency of the databases.
If you are interested in a career as a data engineer, then technologies that require hands-on experience include Hive, SQL, R, Ruby, Java, and C++. It would also help if you can work with popular data APIs and ETL tools, etc.
Database Administrator
They are responsible for the proper functioning of all the enterprise databases and grant or revoke its services to the company’s employees depending on their requirements. They are also responsible for database backups and recoveries.
Some of a database administrator’s essential skills and talents include database backup and recovery, data security, data modeling, design, etc. If you are good at disaster management, it’s certainly a bonus.

Machine Learning Engineer
Machine learning engineers are in high demand today. However, the job profile comes with its challenges. Apart from having in-depth knowledge of some of the most powerful technologies such as SQL, REST APIs, etc., machine learning engineers are also expected to perform A/B testing, build data pipelines, and implement standard machine learning algorithms such as classification and clustering, etc.
You need to know the technologies like Java, Python, JS, etc. Secondly, you should have a firm grasp of statistics and mathematics. Once you have mastered both, it’s a lot easier to crack a job interview.
Data Scientist
Data scientists have to understand business challenges and offer the best solutions using data analysis and data processing. They must have a combination of analytic, machine learning, data mining, and statistical skills in addition to experience with algorithms and coding.
To become a data scientist, you have to be an expert in R, MatLab, SQL, Python, and other complementary technologies. It can also help if you have a higher degree in mathematics or computer engineering, etc.
