Student Worker

I worked as a student helper with a high variety of software development tasks. Most development tasks included back-end development in C#, Java, Python and front-end, such as ReactJS, JavaScript, HTML/CSS etc. I have created a number of services and tools which automated processes. I was also involved in data projects where I built dashboards to better visualize and understand data from a number of IT systems in Siemens.

Student Group Lead

I worked as a student coordinator for ca. ten students in Mobility division. My primary responsibilities were:

• Search for study projects in the organization and cooperation with different stakeholders in Siemens;
• Prioritization and coordination of projects;
• Employment of new students and planning of resource allocation;
• Making sure that the software students develop is easy-readable and well-documented;
• Mentoring on the students on their and their tasks and on productive;
• Finding new ways to improve software development and communication between stakeholders;

Software Developer

I was a member of an international software development team in a large-scale software project, where I developed software in Java EE by applying agile methodological principles. My primary responsibilities were software development and participation in many daily meetings, where I learned about the software we develop and other technologies. In these meetings, I suggested improvements concerning software development processes and team dynamics. I worked as a student, mostly part-time until August 2016, then full-time until February 2017.

Student Worker

I provided support to employees in Siemens Denmark, Mobility division concerning a wide range of problems ranging from managing user accounts to solving network problems. My primary responsibilities were ad hoc support, finding ways to improve and protect the network and development of new services that can automate tedious administration tasks.

The following descriptions are some of the many tasks I performed:

• Maintenance and development of computers hosting Linux, Windows and Windows Server operating systems;
• Administration of a server hosting Active Directory on a local domain controller;
• Monitoring and administration of multiple virtual LAN networks in the network;
• Scripting to automate tedious network administration tasks;
• Troubleshooting network problems;
• Maintenance and creation of software documentation.

IT Intern

I was part of the Engineering department in Mobility division, and I helped with solving IT problems, enforcing better network security and developing software.

The following task descriptions are some examples of larger jobs I have been doing:

• Developed Windows Communication Foundation (WCF) services in C# that authenticate users via Lightweight Directory Access Protocol (LDAP):
• Created a service that allows network's users to unlock their Active Directory (AD) accounts and change their passwords, which automates the process of managing user accounts and thus, this implementation relieves the pressure of system administrators, who were responsible to manage user accounts before.
• Designed a synchronization system, where network's computers daily send their status (whether certain programs are running and configuration files are up-to-date) to a WCF service, which establishes communication channel between a few security applications and enables configuration synchronization between a server and client machines. This allows an administrator to change configuration of security applications only on the server and then the changes propagate to all other synchronized computers without the need to log in on every single machine and change the configuration.

• Developed a Windows Presentation Foundation (WPF) application that facilitates search functionality of an internal website. This speeds up the search function of the internal contact directory by allowing employees to use a WPF application that sits in the corner of computer screen and can be accessed in seconds. This application then fetches information about employees from the internal LDAP server.

• Maintained and developed the internal network. Used VMware to create and manage virtual Linux and Windows machines. Managed the internal network's AD and VLANs.
