Completed UCSD’s Big Data Integration and Processing on Coursera with 97.7%. Covered MongoDB for querying JSON data, Pandas for data analysis, and various Spark technologies — Spark SQL, Spark Streaming, Spark MLlib, Spark GraphX. A hands-on exercise involved analysing tweets using both MongoDB and Spark.
The specialisation as a whole is fairly introductory — broad coverage rather than depth — but valuable for building awareness of the ecosystem and knowing where to start when you need to apply these tools.
