Merkle Inc.

Columbia, MD
Senior Database Application Developer
April 2013 - July 2016

Business Environment:

Merkle is the nation's largest and fastest-growing performance marketing agency. Merkle helps brands transform their marketing organization using data, analytics, and technology to create meaningful, personalized customer experiences that deliver competitive advantage.

Certification, Recognition and Awards at Merkle:

Certified Merkle Digital Professional: I have attended 10 classes and passed 11 exams to be certified MDP

Merkle One Team Award – for Hadoop Migration work from Cloudera to Horton works

Merkle attribute award - Passionate – for helping another team for an oracle database related project

Merkle attribute award - Sense of Urgency – for diligently working on getting a client’s corrupt reference base back.

Projects and Responsibilities:

I was part of the team that was responsible for developing and maintaining an Enterprise wide reference base (Master Data Management) that hosts standardized, consistent and most current data for individual customers for each client�s reference base. This reference base becomes the central source of information based on which the marketing campaign attributions are done. Various other platforms use this as the source data.

Hadoop: Hadoop platform was used to create a Connected Recognition (CR) platform, which include Customer Data Integration (CDI) and Digital Data Integration (DDI). The data was stored in HBase tables, Hive tables and HDFS files. I used Ambari to check the system stability and data node availability. Used HBase Master to monitor proper data distribution to avoid hot spots in HBase tables. This environment handles over 1.2PB of data.

Connected Recognition (CR) - Job automation: I have implemented the automation of daily data ingestion and weekly report generation job for several clients. This includes developing several scripts to move files between Hadoop’s HDFS and SAN, created several Hive scripts and run the Map-Reduce job to process the data, creating jobs in the enterprise scheduling software (Cisco Tidal), and export the report data into SQL server 2013 for billing. This automation framework was eventually applied to all the other clients by using the codebase I developed. This has and will save a lot of time for all client onboarding’s. Involved Bash, Hive, Scoop, Java MR jobs and Python.

HBase table Performance optimization: The rows in HBase tables are sorted lexicographically using the row key. This allows for fast access (acts like a clustered index) by using the start row-key and stop row-key on each region which may or may not be serviced by separate region server. When too many records within a range of start keys (like HASH keys starting with letter S) are clustered together (this phenomenon is called hot-spotting), I split the region and put these two regions on separate region servers. Hot-spotting usually leads to job failures as the uneven write load on a single region puts undue pressure on respective region server, causing region server failure. I used HBase Master to detect the regions server with too many regions and regions that are highly clustered together.

Automated Hadoop MapReduce job execution and Hive scripts and query executions using Python 2.7. On a separate project, I used/tested Luigi to run multiple MapReduce jobs and Hive scripts (Luigi is a python module used to build complex pipeline for batch and jobs).

Automated part of the billing process by using Sqoop to transfer the MapReduce job output from HDFS to SQL server 2012

Legacy Key migration: When migrating Clients from legacy platform to Hadoop based Customer Data Integration (CDI) platform, we lose the ability to attribute a sale to a given marketing campaign. This project allows us to tie the legacy IDs to be mapped to the Current Platform, giving us the ability to attribute a sale to a marketing campaign. * Skills Used: Involved writing several Hive scripts and chaining them using Bash scripts. I created External Hive tables on top of HBase tables.

Migration: successfully migrated MasterSource reference base from legacy KL2 to CR-CDI platform. This is by far the biggest reference base of all the clients we manage on CDI platform.

HBase Snapshots: Successfully managed (created, Restored and dropped) HBase table snapshots in several instances to restore a corrupted reference base for individual clients

Connected Recognition - CDI - POC implementation: Proof of Concept database is a small scale database hosted on SQL Server 2012 database on a smaller scale of data (not exceeding 10 million records). Once the client team reviews the output data and approves the match rules, then the actual data is ingested on to the Hadoop Platform.

Tier 3 support: For connected recognition (CR) and Knowledge Link (KL), I am part of the team that provides 24/7 hours support on a rotating schedule basis. I was called several times late at night and I took I resolved the issues and brought the solution/process back online. Several times, I had to initiate SWAT calls, bringing everyone necessary and took the lead to successfully resolve the failures. * Skills used: SQL expertise, System integration knowledge, Knowledge on Hadoop stack (HBase, Hive, HDFS file manipulation, Sqoop, HBase Master, HBase hotspot detection, etc.), Cisco TIDAL – Enterprise scheduling software and leadership and managerial skills.

Data Analysis: Perform data analysis by extracting data from HBase, Hive, HDFS files, SQL server 2008/2012, Oracle 10g and Netezza Knowledge link 3 platform: I have developed and implemented several functionalities and improvements to the platform. Some efforts include feature development and implementation, bug fixes, etc. Involved Bash scripting

CR - Digital Data Integration: I worked on modifying the T-SQL code embedded in the java code to process input data. Paraccel Upgrade feasibility study: Paraccel (Actian Matrix) database is a parallel relational database system using a shared-nothing architecture and columnar orientation. I did the upgrade feasibly study; this involved, setting the environment on a newly built test cluster, import sample data, test connectivity from local and remote access. Ensure the SQL parsing engine would support the existing code base.

Hadoop environment conversion: I am part of the team that migrated the Hadoop environment from Cloudera to Horton Works. Played a role in testing the successful migration of Sqoop, HDFS and HBase usability. The conversion team received recognition and award in a company-wide quarterly meeting for successful migration.

On-boarded several clients onto CDI platform and KL35 platform: On-boarded T-Mobile, Sanofi, PayPal credit, ESPN, MetLife, Abercrombie, Cedar fair, Decker’s, Medical mutual, Regions bank, Sun power and more

Worked on KL35 to CDI migration effort: worked on migrating several clients like Oriental trading co, AAA, Dell, Carters, Chase home equity.

On-boarded clients to Standardized DDI solution: Geico, 1-800-flowers and Toyota

Documentation/technical manuals: Created several Standard operating procedure (SOP) documents that are used by the Production operations group for the management of CR-CDI and CR-DDI applications. Detailed instructions for failure recourse and escalation procedures are documented as well.
