Professional Duties ==> Technical Consultancy and Customer Big Data Analytics for Advanced Software Analytics.

During my employment at Seerene, I was responsible for two duties, namely, technical consultancy and customer big data analytics.

Under technical consultancy, I have interacted with the customers to tailor the online “Code+Management”

platform of Seerene according to their specific needs. I have also done static and dynamic analysis of the

visualization of data as well as the underlying raw data to help customers better understand the online

“Code+Management” platform of Seerene.

Under customer big data analytics, I have programmed extensively in R and in Python to generate customer specific extension of statistical information and visualization of statistical information of the online

“Code+Management” platform of Seerene. Additionally, I have generated several usage statistics, based on various diverse criteria, on the online “Code+Management” platform of Seerene.

Professional Duties ==> Software Development and Maintenance Cost Estimation Model.

I was responsible for developing Effution proprietary software maintenance lifecycle model. The model was based on the ISO/IEC 14764:2006 standard. I have developed the complete list of the module structures and the t-table structures of the salient applications of the SAP business suite. Especially I have identified the customizable t-codes in the module structures and the t-table structures of the salient applications of the SAP business suite. I have been involved in the development of the method and the procedures for mapping between the SAP WRICEFT class and the complete list of the module structures and the t-table structures of the salient applications of the SAP business suite.

Additionally, I was involved in the development of Effution proprietary software lifecycle cost estimation model

for estimating cost, effort and schedule of SAP projects. I was responsible for conducting calibration of M(A), M(B), T(A), T(B), scaling factors and environmental factors of the COCOMO-II cost estimation model based on the historical project data of Effution. I have developed algorithm for assigning backfiring values in the Effution

proprietary function point-based cost estimation model.

I, along with colleagues, have conducted cost, effort and schedule estimation of number of customer-assigned

projects using function point method and use-case point method.

Professional Duties ==> Safety and Safety-Related Security Analysis for Safety-Critical Cyber-Physical System.

I was responsible for conducting research on safety analysis and combined safety and security analysis. The

principal focuses were to analyze safety hazards and the effects of security threats on the occurrences of safety

hazards in safety-critical cyber-physical systems. I, along with my colleagues, had constructed component fault tree and state/event fault tree to perform safety analysis of such systems. I had also constructed combined component fault tree and attack tree to understand the effect of security threats on the occurrences of safety hazards in safety-critical cyber-physical systems. All these analysis activities had been performed in a strong collaboration with Fraunhofer Institute of Empirical Software Engineering (FhG-IESE).

Additionally, I was responsible for conducting empirical evaluation for comparing performance between

Dynamic Fault Tree (DFT) and State/Event Fault Tree (SEFT). The aim of the evaluation was to compare the two

analysis techniques in terms of their consistency, expressiveness, maintainability, complexity, and error-proneness.
