Experience

DHL Express Europe Oracle E-Business Suite R11 to R12.2 Upgrade

I custom-developed the SQL, PL/SQL, BI Publisher, OAF, Forms, and Bash. I also implemented the SQL and database performance tuning (with more than ten terabytes and more than one billion rows of tables). In addition, I provided hardware optimization guidance.

DHL Express Global

I developed a mobile application for DHL Express workers, using Oracle PaaS. I was involved in requirements and gap analysis, testing, performance tuning and writing complex SQL queries for the Oracle Database.

Financial Business Planning for the Slovenian Steel Industry

I developed a custom eBusiness suite module for multi-user plan generation, modification, and analytics with custom version control on every field of every plan. I also created a custom Oracle EBS Web ADI integrators as the UI for the plans and developed extremely efficient complex views for real-time extraction and aggregation of all relevant EBS data. Lastly, I created an Oracle BI repository for plan analytics.

Oracle EBS Customization for the Slovenian Steel Industry as an Oracle Consulting Subcontractor

I developed custom BI Publisher Reports, Oracle Forms, and Web ADI integrators for the Oracle E-Business Suite 12.1 in a multiorganizational context, covering a broad range of financials and manufacturing modules.

Custom Oracle EBS Reports for KBC Zemun Hospital

I wrote Business Intelligence Publisher reports for the financial and inventory parts of the hospital's system as a member of an Oracle Consulting implementation team for Oracle eBusiness Suite. All my reports required writing very complex SQL for the Oracle Database.

Anti-money Laundering Application for the Serbian Anti-money Laundering Agency

I developed a data warehouse using Oracle Warehouse Builder for ETL, a custom PL/SQL for data matching, Oracle BI for analytics, and BI Publisher for reporting. Also resolved very demanding performance issues by optimizing SQL, database, and hardware configuration.

Central Database and Migration of Data for the Serbian Fund for Pension and Disability Insurance

I designed and implemented the central Serbian social insurance Oracle database, then cleansed and migrated data from legacy PL/1 and COBOL applications. Configured and tuned the pilot Oracle Database.

Data Migration into Oracle EBS for Belgrade Electric Plants

I developed custom PL/SQL procedures for Oracle EBS for the migration of data from legacy applications. Also, I created the most demanding reports on the new database and performed performance tuning of other reports.

High Volume XML to an Oracle Database Import for the Belgrade City Billing System

I imported and parsed one million very complex XML documents in a few minutes using BaseX and an Oracle SQL Loader data pump. I then analyzed the total Oracle database performance and resolved all critical performance issues.

Oracle EBS Enterprise Asset Management Implementation for the Belgrade City Maintenance Service

I created a requirements analysis and EAM solution design for the municipality company maintaining 600.00 buildings in the Belgrade area, for implementing Oracle eBusiness Suite EAM, inventory and manufacturing modules.

Fast Oracle SQL Query for an Automotive BOM Analysis for ROHS Compliance

I developed the most demanding Oracle Database SQL for the automotive software vendor AD-CS AG which was used by GM, Nissan, Emerson, and others. Anything SQL or PL/SQL that this vendor's development team was not able to make run efficiently, was forwarded to me.

Development of an Internal CRM and BI System for Oracle

As a general manager of Oracle Russia in 1995, I personally developed a custom CRM application using Oracle Designer, Forms, and Reports, which covered all aspects of sales, forecasting, delivery, collections, and support; it also successfully achieved exceptional sales and support force productivity and the best business results in EMEA. I used the beta version of Oracle Discoverer to build a BI system so good that I stopped preparing slides with business results for regional management reviews and used live Discoverer reports and ad hoc queries to answer immediately. This meant that the most complex questions were answered in seconds instead of days like my colleagues in other countries.

This system was in use for over 20 years by Oracle Russia.

USA Real Estate Data Warehouse

I handled the Oracle Database, SQL, and PL/SQL performance tuning of the largest real estate data warehouse in the US for Smarter Agent. I also designed an optimal partitioning scheme for frequent data loading and online availability.
