During my 5 years at HTL Leonding I gathered experience across many fields of Computer Engineering such as:

Hardware

• Physics of Semiconductors
• Analog/Digital Circuits
• CPU Architecture (von Neumann, Harvard)
• VHDL
• PCB Design

Software

• ASM
• C
• Java
• C#

Service/Repair Elevators

Development of webservices using Java for the finance sector.

After graduating from HTL Leonding I was still unsure whether to pursue a career in Hardware or Software.

At Sierzega Elektronik GmbH I gathered a lot of practical experience about manufacturing and repairing electronics. Because of the rather small size of the company I was also able to gain some insights about operating a successful business.

My main responsibilities were:

• Component Level Board Repair
• Pick&Place Machine Usage/Maintenance
• Assembly of Radar Speed Displays
• C# (WPF/WinForms, SerialPort)
• Web Development (plain HTML/CSS/JS)

While very interesting, I eventually decided that I wanted to specialize in Software Engineering which was the main reason I ended up leaving the company.

To fulfill the ever increasing quality demands of various customers of voestalpine I mainly worked with a team of about 6 people to perfect systems and processes that gurantee a certain level of quality of voestalpine products.

Developed internal tools to analyze and visualize the data generated by multiple Surface Inspection Systems. Another important aspect of this position was communication. Even the best software cannot make up for a lack of domain knowledge among developers and operators.

Programming Languages:

• Kotlin (JavaFX)
• C# (Windows Services, Data Processing)
• Python (Data Processing, Machine Learning)
• C++ (Qt, STM32)

Database Systems:

• MSSQL
• OracleSQL
• PostgresSQL
• InfluxDB
• Cassandra

DevOps:

• Windows Server, SLES, Debian
• Gitlab CI/CD, Docker, Sonarqube, Nexus Repository
• Grafana, Loki

I moved to Japan to learn more about this fascinating country and experience a different culture in a way not possible as a tourist.
