Freelancer profile translated to English.

Description

With over 25 years of professional experience, I support client projects as a reliable partner in my roles as Senior Data Engineer, Architect, and Project Manager.

I have had the opportunity to cover a wide range of industries and IT ecosystems, from agile start-ups to Big Data environments with clients such as Siemens, IBM, Allianz, MAN, and many others.

Whether in solution design and development of data warehouses or database solutions, individual ETL/ELT pipelines, or data lake implementations for analytical purposes, I place a special focus on holistic and sustainable approaches that enable reliable operation for many years to come. In addition to technical requirements - both functional and non-functional - other factors are also considered, such as the expected development of the data structures used, volume frameworks, regulatory requirements, or staffing during operation and interfaces to third parties, which have important implications for the degree of automation required.

I would be pleased to support you in your next project and am always available for a non-binding introductory meeting.

Sincerely,

Alexander Loithaler
