• Part of a small team developing factory automation software.
• Re-architected, developed and tested a highly concurrent factory automation software application. Much of the existing code was replaced or refactored to increase scalability, reliability, concurrency and performance..

• Embedded in a backend development team, testing both server and client applications. The job required extensive knowledge of the interconnected services involved, including web apps and mobile phone apps.
• Tests of backend REST APIs, frameworks, databases, message brokers and applications using exploratory testing, assisted by writing test programs.
• The software that was tested used Java, Rabbit MQ, MySQL, Cassandra and JavaScript.Python scripting was used to automate tests. Bash tools, regex and BareTail Pro were used for log analysis and filtering. ZFS with.

• Development of the laser-based soot diagnostic technique laser-induced incandescence, LII, used to measure soot particle sizes directly in the burning gas of a flame, for example inside an engine or a gas turbine.
• Designed and built a new experimental set-up of infra-red lasers, advanced optics, burners, detectors and cameras, with everything optimized for high precision.
• Used an existing codebase in Matlab to analyse the experimental data, and developed and highly optimized the code to meet new demands and to answer new questions.
• Implemented code in Matlab to use Monte Carlo simulation to model the heat conduction rate from simulated, fractal-shaped soot particles to ambient gas. Also extended the model and the code to investigate more.

Doktor I Fysik / Phd In Physics, Combustion Physics

The PhD studies were within the field of laser-diagnostic measurements in combustion processes. Specifically, it involved development and.
