Work Experience
Data Analyst
Trust & Safety Laboratory
- Automated the collection of social media accounts spreading misinformation from multiple fact-check sites.
- Utilized Hugging Face's CLIP model for zero-shot learning to detect harmful content in images.
- Performed analyses to visualize bad actors and their friends of friends network graphs.
- Translated client requirements into interactive dashboards in Tableau.
Data Scientist
Turkish Aerospace Industries
- Developed a dashboard-based surveillance system to improve a factory's work processes using IP camera recordings. Applied video and image processing algorithms using the OpenCV library together with object detection and object tracking algorithms.
- Built an LSTM-based model to identify people's actions and improve work processes in a factory.
- Developed a predictive maintenance model using ARIMA and LSTM algorithms which provides insight into a plane part's breakdown using the time-series data of a plane component. Applied data manipulation, analysis, and visualization.
Machine Learning Engineer
Vitus Commodities
- Took part in several data scraping projects using Selenium, API calls, the requests library, and more.
- Created reports on Microsoft Power BI for data visualization.
- Implemented a multilayer perceptron model using Python and Keras to forecast the natural gas demand in the UK for the coming days.
- Deployed an LSTM model that predicts Turkey's electricity price for the next few days.
- Implemented a scraper to obtain and manipulate GFS weather data to use as a source for model training.
- Investigated deep learning methods to enhance the performances of the current working models for time-series data.
- Implemented an outlier detection project consisting of probabilistic and clustering-based algorithms and an autoencoder method to detect extreme days concerning the UK's natural gas demand.
Machine Learning Engineer
Independent Work
- Implemented data preprocessing, data imputation, feature extraction, and model creation modules for the Vitriol project using Scala.
- Researched and tested a meta-learning strategy to predict the best model with the best parameters for a given problem using Scala and Spark.
- Implemented a parser to handle unstructured data that comes from different sources using Python.
- Worked with big data using Apache Spark framework and Scala.
Software Developer
C3S Command Control & Cybernetic Systems
- Developed connector reliability testing software that controls the connection between PCI cards and connectors on the Linux platform.
- Built software that calculates how much time an employee spends at the office.
- Wrote SQL database queries to analyze an employee's working schedule.
Software Test Developer
Taleworlds Entertainment
- Developed automated tests for Mount&Blade: Bannerlord II project.
- Monitored test results and reported bugs found in prerelease software on a daily basis.
- Performed unit tests and integration tests to determine if the game scenes were working correctly.
- Worked within an Agile environment with multiple teams.
Software Developer
TUBITAK | The Scientific and Technological Research Council of Turkey
- Developed a parental control tool for Pardus, a Linux distribution supported by the Turkish government.
- Implemented content filter, usage control, and monitoring modules.
- Gained experience in open-source development and the security field.
Experience
Vitriol
http://senior.ceng.metu.edu.tr/2016/mallorn/I used a meta-learning strategy to select the most appropriate algorithm and its parameters. This project is implemented in Spark and the Scala programming language to handle big data.
Natural Gas Demand Forecasting
First, I implemented an extreme day detection module to label the data as extreme or not extreme. An oversampling method helped enhance extreme days because they were a small portion of the data. I also implemented a dynamic weighted ensemble model using a multilayer perceptron (MLP) and a linear regression model to consider both linear and non-linear trends.
