Work Experience
Lead Database Architect
Treehouse Technology Group
- Worked on Salesforce, Salesforce Marketing Cloud, ABC Financial, Sage Integrations, and developments of back-end procedures using SQL and PL/SQL for the reporting layer.
- Selected and optimized AWS services according to scheduled jobs and queries that run in DBs. Monitored AWS metrics closely and took the related query and configuration optimizations. As a result of this, services are selected cost-efficiently.
- Created Data Build Tool (dbt) templates of the ETL process to streamline the process and make it efficient and understandable for all junior developers.
Senior Business Analyst

Experience
Oracle ERP | P6 Primavera Integration Project
I was the database and back-end developer of this project. I created the necessary web services and scripts integration using PL/SQL and XML. Also, I built Tableau dashboards to monitor real-time integration status.
Oracle ERP | Master Data Management Software Integration Project
I was the back-end developer of this project. I was responsible for developing the web services required for the integration and PL/SQL scripts, which trigger necessary events in the Oracle database.
Information Verification System Using Unstructured and Structured Evidence from Wikipedia
https://github.com/orkuntemiz/MetuISFeverI developed a machine-learning model for text extraction and deep learning models to verify extracted texts. To obtain the ground truth about the claim and query enhancement, I integrated it with NoSQL and relational databases used via query requests sent from Python.
Tableau Dashboards for Production Planning and Scheduling
I worked both as a data analyst and database developer in this project. I created necessary raw data using SQL queries from an Oracle database and developed Tableau reports for data visualization and data storytelling.
Excel VBA Script for Material Requirement Planning
https://github.com/orkuntemiz/MaterialReqVBACUDA-enabled Parallel Programming Implementation of the KNN Algorithm
https://github.com/orkuntemiz/ParallelKNNCUDAI developed the CUDA code with a C++ platform using Visual Studio as the IDE.
This project aimed to efficiently classify a high volume of data, and the algorithm is used in a medical document classification script developed in Python.
