Personal details
Marek S.
Summary
I have graduated from the Technical University of Kosice with a master's in Computer Science, in 2010. During my time at university, I have already worked part-time, which allowed me to gain practical experience while earning my degree.
After graduation, I joined Eset, where I worked on the Eset Mobile antivirus solution, beside standard development tasks, there were also a lot of reverse engineering tasks and penetration testing. This was my first professional job, and it set the foundation for my future work in security-related positions.
Throughout my career, I was always working on backend services or Android OS/Apps or IoT, using programming languages such as C++, C, Java, C#, and Python. I have also designed and build from ground up a Public Key Infrastructure (PKI).
Threat Modeling is a process I am well versed in, and I am a strong advocate for implementing it for all projects. In addition, I have a side project focused on providing complex solutions for on-demand last mile delivery services, with the goal of increasing efficiency and speed.
Overall, I am a motivated and experienced professional with a good understanding of security-related technologies, programming languages, and the Android/Linux/Windows OS. My past experiences has equipped me with the necessary skills to tackle any challenges I may face in my work.
Technical skills
Work Experience
C++ developer, member of the Data Connectors team which was responsible for implementing connectivity to a variety of data sources such as databases, data streams and all kind of file types. I mainly focused on the implementation of secure credential storage, authentication and authorization features. I have also introduced Threat Modeling to Alteryx and began the integration of it into the development lifecycle. I have discovered a few vulnerabilities by doing Penetration testing.
FROM 2018 UNTIL 2019 C++ developer as part of the Platform team responsible
for developing a custom Linux (Yocto) based platform used across all Kistler products. My
focus was on implementing security related features. Development was done using C++11
and later C++14 standard.
FROM 2019 UNTIL 2021 SECURITY ENGINEER as part of the Platform team
responsible for transforming the existing (insecure) platform into a secured platform which
meets the latest security standards. This was achieved by implementing a security
framework TOGAF into the platform lifecycle. Also, numerous Thread-Models were created
in the process of transformation. I was responsible for designing various security features
both on device side and on the backed (cloud-based AWS) side. I have also designed a PKI
solution which covered business requirements from all existing and future Kistler products
as well. I have led a team of developers implementing the PKI solution
