About

My experience as a programmer analyst and software developer contributed to successful enterprise application launch for government and private sector projects. Analysed the data, business requirements and created a data model that supported the application and reports in real time. Designed and Developed complex B2B transformations that creates EDI files, Extract Transform and Load (ETL) code for data warehouse, real time application back-end OLTP database and conversion projects. De-identified/masked production data (PHI/PII) for ETL and Application development and testing. Designed and developed a software in Linux using bash scripts that can de-identify/mask PHI/PII data in any type of Electronic Data Interchange (EDI) X12 files. This software helped the client to test the application faster using de-identified files. Compared to traditional software like Informatica masking transformation, Informatica developer (B2B, HIPAA Libraries, Parser, Serializer, and Unstructured data transformation), this software reduces development time almost to 60% and saves licensing costs. Written DB2 store procedure that dynamically creates Insert statement SQL for each application table and creates test data in all application tables (maintains data integrity). This procedure takes existing application ID and count as input. This helped testing team for application performance testing. Designed and Developed Python (Pandas, tkinter) GUI Software that takes Sql scripts as input and validate against set of pre-defined rules.
