Philipp Schreiber, Cologne, Germany, Europe, Earth

Seasoned (14 years industry, 42 years age) software developer with strong product development and lead skills. Background in ecommerce, b2b and b2c service implementation and operation. Broad stack of technology. Pragmatic approach. Thorough experience in hands-on web-development. Mostly CRUD applications of various sorts and sizes. Meddling in product management a lot, mostly advisory, sometimes annoyingly so. Also thorough experience in keeping shit from fellow devs, getting them appreciation and giving them space to tackle challenges, gather new experiences, making the most of their abilities (otherwise known as management or leadership). Totally comfortable not to be the smartest or most knowledgable in any given room of devs, quite on the contrary. Since 2015 my priority #1 is my daughter.

Let’s talk:

Professional Experience:

Data Engineer / Senior Software Engineer

DeepL SE Aug. 2022 - today Köln, Germany

Evolving data analytics platform in high scale multi DC environment. Sinking big data through Go, C# and python services from kafka into clickhouse. Making use of protobuf and GRPC along the way… and a lot of monitoring and alerting.

Head of Software Development

Justix GmbH Nov. 2019–Aug. 2022 Köln, Germany

Idea, concept, strategy, realization, people… the whole deal. Still coding. Key aspect at justix is probing legal tech market with greenfield products. Strategy is to establish platform fundamentals to allow quick go to market. Weapons of choice are lightweight backends written in PHP, symfony and API-platform around which several logic heavy frontends in react.js and vuejs create various experiences like B2B2C legal document assembly tools or the swiss army knife of access to justice at HelloLaw.

I’ve established the 6 people (including me) dev department plus one DevOps person, which I split up into two teams for our two separate product areas.

Not only am I the responsible person for bringing envisaged services online timely, I am also much involved in conceptualizing new ideas and turning them into product objectives. On the other hand I also practice saying “No” a lot in order to keep focus as much as possible and only do things that add value.

Governmental Teacher Trainee

Konrad-Adenauer-Gymnasium Feb 2007-June 2007 Langenfeld, Germany

Teaching English and German in the German university-qualifying highschool track (Gymnasium). The logical step after graduating from University with the “1. Staatsexamen für die Lehrämter Sekundarstufe II und I”. High school teaching just wasn’t for me. So I pivoted as early as possible.

Universität zu Köln 2000-2006 Köln, Germany

Full academic degree in German and English and educational sciences as minor. Equivalent to Master of Education. Governmental teaching track, which results in a state exam. So, yes, my completed formal education is in the humanities.
