Detailed Work Experience

Merit Energy Company (HANA Architect / Developer)

Jul 2014 – Present

Merit Energy Company uses Quorum software to administer their land mapping and oil production tied with SAP financial data. Quorum Company

also sells analytics based on SAP BOBJ to their many clients. However for years their performance had been very substandard and in some cases

their measures wrongly doubled up. This issue had been plaguing multiple quorum clients. Merit wanted to independently rework the solution on the

HANA platform and also to eliminate the measures multiplying wrongly. Merit had hired a specialized HANA firm in 2012 do this as a POC. The 4

member team delivered on HANA in 3 months, however, the performance was not up to the mark and the measures still wrongly multiplied. I came

on board in July 2014 and within a month delivered a solution that was blazing fast and the measures added up correctly. The classic problem of

multivalued dimensions was solved by using HANA windows functions.

  · Data Services was used to bring the data from ORACLE DB

  · Much of the logic was ported into Data Services combining many ORACLE tables into sets of single HANA tables.

  · HANA Window Functions was used to circumvent the earlier issue of doubling measures.

  · The front end was delivered using BOBJ universe and WEBI.

  · Existing reports on MS SQL is being converted to HANA models and Design studio replacing Xcelsius Dashboards

  · Ongoing work is reworking classical SAP BW to optimized mix modeling BW on HANA.

  · BW Planning Functions logic embedded in ABAP is being modified to SQL scripts.

  ·

  ·

Installed and Maintained SAP Data Services and SAP HANA including writing installation guides.

Involved in SAP BPC development.

Accenture (Role: SAP Big Data Architect)

Phillips66

Feb 2014 – Sep2014

SAP HANA, Sybase IQ and Hortonworks HADOOP are being used in conjunction with Predictive analysis. PAL algorithms are being used to study

for outlier analysis, preventive maintenance by using the HANA time-series, classification and clustering algorithms. Data is fed in HADOOP via

DataServices in nightly batches. HADOOP uses map reduce via (HIVE/PIG) to extract, enrich the relevant data into tabular format within HADOOP.

HANA pulls HADOOP data using both federated and within HANA depending on the use case. For reports and analysis, data is bought directly in

HANA but is federated via SDA for predictive analysis. 3 Tier systems with HANA for HOT data, IQ for WARM data and HADOOP for Data

Dump is being Architected.

  ·

Oil flow logs and sensor data is bought into HADOOP HDFS via Data Services.

  · HIVE is used to parse the log data to extract key flow related parameters like flow rate, viscosity, co-efficient’ s and extract it into ORC

format (Optimized Row Columnar).

  · Sensor data is also formatted into a tabular structure within HDFS with key data like pressure, temperature, bore diameter etc.

  · Ozzie is used to drive the entire workflow within HADOOP

  · Data is pulled into HANA via nightly jobs by data services and modeled as views combining fact table from HADOOP with dimension

tables from HANA.

  · SDA is used to pull data from HADOOP (Federated approach) to model predictive analysis algorithms and visualizations in Lumira.

  · Modifying HANA Live Content.

Accenture (Role: HANA Architect)

Shell

Nov 2013 – Jan 2014

WRFM plant maintenance data was captured via third party tools and via SAP PM Notifications. The data was SLT’ed into HANA and models built

for reporting. Predictive capabilities of HANA were used to do exploratory analysis of the data using Lumira as the front end display tool. The drill

down to specific component details was achieved by creating OData services on HANA tables with SAP UI5 as the front end.

  · Developed Scripted Calculation views with embedded 'Read-Only' Stored Procedures.

  ·

Created and consumed ODATA Rest Services on HANA tables and consumed ODATA from UI5.

  · Co related hypothesis for Plant issues with PAL algorithms

  · Distribution by defect hypothesis to Classification algorithm , defect frequency to Extrapolation algorithm

  · Ran in database Predictive Algorithms in HANA and used Lumira to display simple results and co relations.

Accenture (Role: HANA Architect)

Verizon

Jan 2012 – Oct 2013

HANA Phase II: included creation of Financial Close models from SAP and non-SAP data to create BOBJ reports using WeBI and Analysis for

office. There was Real Time Data Provisioning via SLT from ECC to HANA and from ORACLE to HANA. Another component was to send GL

summary data from HANA models to an external CPM system via Data Services. This was to achieve a 360 degree reporting.

HANA Phase III: included a mix mode SAP HANA and SAP BW on HANA approach where there were standalone HANA models, HANA models

exposed as Virtual Providers in SAP BW and finally classical BW on HANA models. The latter made use of in-Memory Optimized DSOs exposed

thru Multi-Providers and BEX Queries and use of in-memory optimized cubes when aggregating data with different granularity.

HANA-HADOOP Phase I: Hadoop win conjunction with HANA is being used to evaluate Verizon call drops over the country. The Data would be

used to identify the moving customer base density and bettering the telecom infrastructure on most commonly used routes.

• Designed and Architected solution for HANA Phase II and Phase III Implementations

• Developed HANA models and BODS flows for Phase II and Phase III.

•

Created HANA and BW on HANA mixed models using Virtual providers.

• Moved SAP BW specific models to hybrid BW on HANA and pure HANA paradigm.

• Developed custom ABAP SLT for prepopulating data for performance optimization

• Found novel workarounds to multiple Problems/Issues.

•

Created re-usable methodology for Recursive Hierarchy, custom SLT enhancements, HANA Performance Optimization techniques, HANA

Stored Procedure calls by Data Services.

Key Strategies used to overcome limitations of HANA and to improve performance

• Trigger stored procedures and data push via Data Services due to Lack of scheduling at the HANA DB level.

•

Introduced lag in the incremental feed to counter latencies in data replication via real time SLT.

• Developed Write enabled Stored Procs initiated by data services that would do the join on data chunked into smaller subsets and populating

a table to counter crashing of HANA on joining Massive Tables.

• STL transformations were used to pre populate the tables with additional fields with the complex logic already built into the fields to

counter performance degradation due to nested complex logic and IF statements in HANA models.

• Alter Scripts were used to create auto-generated columns to push calculations down to the HANA DB level and to convert and persisted

Data-types needed for the joins. This was done to do join on different data types from disparate sources.

• Enable decimal shift feature in the HANA models and model time travel.

• Advanced Parent-child Hierarchy modelling, and using SPs to flatten and prepopulate the hierarchy data.

• Event based SLT transformation to counter parameter based SLT limitation of 3 input parameters.

•

Eliminating Massive Joins by Doing Trick Unions with Constants to improve performance.
