Not teaching currently but instructing a couple of theses.
Please do not hesitate to contact me if you are interested in working with a Bachelor's thesis, a Master's thesis or a Special Assignment with my help and guidance as an instructor.
2018-2020 I worked in the industry (Finnair, Visma Consulting / Weoptit) on topics related to eg. supporting operational planning with optimization technology, software development, resource planning, prediction. This period expanded my knowledge, e.g., on working with customers, general management, project management, sales and marketing.
