Data En­gi­neer

Be­fo­re my last prac­ti­cal pha­se star­ted, I had to ap­p­ly for a job and thus de­ci­de what I wan­ted to deal with in my pro­fes­sio­nal life and in which di­rec­tion I wan­ted to de­ve­lop fur­ther. The po­si­ti­on of data en­gi­neer see­med to be the right one for me, as I had al­re­a­dy dealt with data pro­ces­sing and ETL pro­ces­ses du­ring my dual stu­dies and was en­thu­si­a­stic about them. Af­ter the suc­cessful in­ter­view, I joi­n­ed the PSDS team (Pro­duct & Source Data Stan­dar­di­s­a­ti­on) for the fi­nal prac­ti­cal pha­se, whe­re I wro­te my bachelor’s the­sis. I then of­fi­ci­al­ly joi­n­ed the team as a Data En­gi­neer on 1 Oc­to­ber 2022.

As my first task, I was as­si­gned the ana­ly­sis and trans­for­ma­ti­on of Maz­da data. Per­so­nal­ly, I think that was a good start. On the one hand, it be­ca­me clear to me what the main ac­ti­vi­ties and tasks of the team are, and on the other hand, I was able to deepen my SQL know­ledge and gain new know­ledge in the field of re­la­tio­nal databases.

Af­ter start­ing, I con­tin­ued with pro­gramming tasks. Tog­e­ther with the other col­le­agues, I work­ed on crea­ting the vi­sua­li­sa­ti­on tool “Da­ta­Gui­de” for the Tec­Doc data. Du­ring the im­ple­men­ta­ti­on pro­cess, I dealt with Py­thon and va­rious Py­thon li­bra­ri­es, AWS S3 and the to­pic of web hos­ting. Curr­ent­ly, I take care of the main­ten­an­ce and month­ly up­dates of the vi­sua­li­sa­ti­on tool. In par­al­lel, I am al­lo­wed to con­tri­bu­te to the au­to­ma­ti­on of the data pro­ces­sing pro­ce­du­res in or­der to re­du­ce the ma­nu­al work and thus the time re­qui­red to car­ry out the­se processes.

In con­nec­tion with the res­truc­tu­ring of the In­for­ma­ti­on Ma­nage­ment BU, I joi­n­ed the IT&Data Ser­vices team of the IM Di­gi­ta­li­sa­ti­on Ser­vices unit. The team is re­spon­si­ble for pro­vi­ding pro­fes­sio­nal and stan­dar­di­sed sup­port for pro­jects and IT and data queries. I am very ex­ci­ted about my new role, the tasks I get to work on and the chal­lenges I face.
