Skills

I have a great motivation and experience in extracting meaning from large datasets. I have had the chance to apply analytical techniques to business problems in different fields like transportation, aviation, defense, and finance. Having both academic and industrial expertise in data science, I have always approached the business problem with a systematic methodology, a journey starting with problem definition, data preparation and manipulation, data visualization, descriptive or predictive machine learning/statistic models as required for the problem solution. I am also experienced in leading junior-midlevel data scientists as well as teaching colleagues in data science field. I am very willing to apply my expertise in a new field, and a strong company where data driven technologies are rated as valuable. I want to support the business via data driven automated decision making processes.
Skills: Data analysis, analytics, data manipulation, anomaly detection, data science, visualisation, data mining, machine learning, time series analysis, predictive models, predictive maintenance, developed data analysis platforms, SQL, SPSS, SAS (Base, EG, Miner), R programming language, Phyton, PyQt, Minitab, Object Oriented Programming, coding, coding version control, Matlab, Matlab / SIMULINK, modelling and simulation, SSIS, Octave, Microsoft Office applications, MS Word, Excel, Powerpoint, Frontpage

Project history

01/2019 - 09/2021
Senior Lead Engineer, Data analysis
Roketsan A.S. (1000-5000 employees)
Other
The position involved development of analytical tools for automated data reporting, data
analysis and predictive analytics purposes. A data analysis platform was developed to analyse
missile flight data via a standardized methodology, including most types of data manipulation
and exploration techniques as selected by the user. Time series data analysis also included
anomaly detection methods to alert on visualized data and help decision making and root cause
analysis processes. The developed data analysis platforms were not only focused on flight, but
also on production and project management data for missiles. The developed tools had been
designed in line with data science methodology starting from problem definition, data
preparation, manipulation, visualisation, and development of predictive or descriptive analytical
methods as required by the business problem definition.

01/2018 - 05/2019
Part-time lecturer
Istanbul Sehir University (500-1000 employees)
Other
Teaching programming data mining techniques using Phyton to students at College of
Engineering and Natural Sciences.

09/2014 - 05/2019
Data expert in marketing
CVM, Cigna Finance and Insurance
Banks and financial services
The position involved development and application of data driven analytic technologies with
marketing insights for customer value management (CVM). Developed analytics was used to
target customers with high propensity to buy insurance products using statistical models. The
developed models have been proved to increase sales ratio by two-three times compared to
targeting random groups of customers. Analytical skills have also been applied to develop
segmentation models which help to group similar customers into unique segments such that
marketing actions from operations to product development can be designed for each segment
separately according to segment characteristics.

The position involved collaboration with international Cigna Analytics team in Hong Kong.
Collaborative work was also conducted with QNB Finansbank, our affinity partner, in terms of
enriching insurance dataset with further financial information from the bank database to develop
strong analytical solutions.

05/2012 - 08/2014
Engineer/Technologist
DSS, GE Aviation
Other
The position involved development and application of data driven analytic technologies and
combining these techniques with domain knowledge to predict the health of engines during
flight. Developed predictive maintenance analytics tool was mainly focused on early fault
detection of GE engines which aimed to reduce maintenance costs.

Daily automated processing of engines data provided airlines with notification of faults that have
been identified. Models were built using Probabilistic Diagnostic and Prognostic System
(ProDAPS) techniques to identify anomalies and a reasoning system has been developed to
isolate particular faults and events from those anomalies.

01/2010 - 02/2011
Demonstrator/Marker
School of Mathematics, University of Southampton (500-1000 employees)
Other
The position involved demonstrating various aspects of mathematical techniques required for
engineering studies to 1st year undergraduate students.

09/2001 - 12/2007
Research Assistant, Department of Mechanical Engineering
Middle East Technical University (50-250 employees)
Industry and mechanical engineering
The position involved leading and guiding undergraduate and graduate level students in range of
courses and projects.
