Senior GIS Developer
• Designed and developed pipeline data management application-PDAT suite
with a complete set of functionalities for maintaining pipeline facilities data
in Pipeline Open Data Standard (PODS) model. This database/GIS product
has been installed in several major North American Oil and Pipeline
companies, including Chevron, Chevron Indonesia, BP, Oneok, Marathon
and Koch Pipeline Company.

2. • As a primary developer for the PDAT suite of products, responsible for
coding stored procedures for line maintenance with complex pipeline
centerline maintenance operations and the process for event loading and
editing using PL/SQL for Oracle and T-SQL for SQL Server database.
• Worked as an Oracle database administrator which included installing,
tuning, maintaining and monitoring Oracle database systems, implementing
storage management, performing backup and recovery operations, exporting
and importing database dump files as well as supporting all database
associated techniques.
• Developed and maintained C++/Python applications to create GIS spatial
data in SDE layers for pipeline data stored in PODS relational database.
• Developed Python/PLSQL application to transfer data between the Pipeline
Open Data Standard (PODSTM
) database model and the ArcGIS Pipeline
Data Model (APDMTM
) database model using a JSON data-interchange
format.
• Developed C++/Python application to implement Geo search operations for
pipeline companies.
• Developed ETL applications to migrate pipeline data from legacy ISAT
database model into PODS database model by mapping all fields and
loading all data.
• Worked in the Client’s office to assist in correcting and/or transferring
pipeline data.
• Developed packages or stored procedures to upgrade PODS models to
newer database versions while maintaining complete data integration.

GIS/Database application to manage seismic shot point data. The
application uses standard seismic data as input and generates SDE layers
(maps) for both shot points and line attributes.
• Designed and developed an Alignment sheets application for generating
quality maps that display pipeline oil and gas assets. This was a very
popular product.
