I am nuclear engineer. I have developed desktop apps with Vb.Net and MS SQL database in my previous job. I have co worked with senior software developers of Microsoft. I was a member of team which have developed national vehicle registry software. I have hands on experience on object oriented programming, multi threading, web services, relational database design. So I have pretty expertise on software development. On the other hand for my academic study about nuclear engineering, I had developed various software by java and python. I have golden badge on problem solving at HackerRank.

In-laboratory development of an automatic track counting system for SSNTD

Radiation Physics and Chemistry, 2017 - Elsevier
In this study, an automatic track counting system was developed for solid state nuclear track detectors (SSNTD). Firstly the specifications of required hardware components were determined, and accordingly the CCD camera, microscope and stage motor table was supplied and integrated. The system was completed by developing parametric software with VB.Net language. Finally a set of test intended for radon activity concentration measurement was applied.

Radon and progeny sourced dose assessment of spa employees in balneological sites

Oxford Academic (Radiation Protection Dosimetry)
The ambient air of spa pools can contain serious RAC that depends on a lot of parameters. In this regard, RAC measurements were executed at the 70 spa facilities in Turkey. The measurements were done with both active and passive methods at ambient air of spa pools and dressing rooms. Thus, active measurements were carried out by using the Alphaguard® with diffusion mode during half an hour, and passive measurements were carried out by using the humidity resistive CR-39 radon detectors.
