Over 9 years of professional IT experience with expertise in Hadoop and Big data ecosystem related technologies.
Over 9 years of professional IT experience with expertise in Hadoop and Big data ecosystem related technologies.
• 6 years of exclusive experience in Big Data technologies and Hadoop ecosystem components like Spark, MapReduce, Hive, YARN, HDFS, NoSQL (Cassandra, Redis, MongoDB, HBase, ArrangoDB), Elasticsearch (ELK Stack), Kafka, NiFi, Oozie, Sqoop, Flume.
• Strong Knowledge on Architecture of Distributed systems and Parallel processing frameworks.
• In-depth understanding of MapReduce Framework and Spark execution model.
• Experience on creating and optimizing ETL workflows.
• Strong experience working with both batch and real-time processing using Spark framework.
• Hands on experience in installing, configuring and deploying Hadoop distribution (Cloudera).
• Very good understanding of Partitions, bucketing concepts in Hive and designed both Managed and External tables in Hive to optimize performance.
• Worked with Sqoop to move (import/export) data from a relational database into Hadoop.
• Experience in handling different file formats parquet, ORC, Avro, Sequence files and Flat text files.
• Hands on experience in Linux, Redhat and Debian based distros, Shell Scripting and some AWS services.
Data Lake Design and Implementation based on Lambda Architecture: we create batch and streaming layer in our solution using HDFS and Cassandra as a Data Store Layer and Spark framework as a Processing Layer.
Using Cloudera Manager for provisioning, managing and monitoring Hadoop Cluster.
Data Pipelines: Designed and developed complex data pipelines and maintained the data quality to support a rapidly growing business.
Create Data Pipelines and the ETL workflows: getting data from some our data sources (Crawler - Nutch, RDBMS, Log files and some Rest services) and process it to generate metadata by calling some web services, transform to appropriate format and clean bad records in a chain of data services using Apache Kafak and Apache NiFi.
Designing appropriate Data Models for inserting data in HDFS and NoSQL databases.
Using HDFS+ YARN + Apache Spark for data analytics and ad-hoc queries.
Installation, Configuration and Performance tuning of big data tools: The Hadoop Stack (HDFS + Yarn + Hive + Spark), Apache Kafka, Apache NiFi, Apache Cassandra, Apache Solr and Apache Zookeeper.
Tuning Cassandra cluster for heavy write situations: create some benchmarks and test our Cassandra cluster to tune it based on our requirement.
