+# Work-Experience
+
+- **Mar. 2023 to Sep. 2023:**
+  - Developer for 2Lambda.co. Role migrated from just coding stuff to
+    architecting and rewriting the whole software from the ground up using a
+    small modular approach instead of the shaky one-off systems in place.  
+    Was later a "nanny for everything".
+  - Did a lot of work to have self-documenting code (i.e. generate documentation
+    from the actual values used in the program, not some comments that always
+    get out of date)
+  - Setting up a knowledge-base (Zettelkasten-approach) to track experiments and
+    hyperlink them to the documentation generated above (and due to Zettelkasten
+    you then get "this thing was used in Experiments a, b and c" automatically
+  - Technologies used:
+    - Clojure
+      - Complete application was written in Clojure
+      - Never touched that language before March - got up to speed in just 2
+        days, poked the expert on the team detailed questions about the
+        runtime-system after 1 month (like inlining-behavior, allocation-things,
+        etc.)
+    - Emanote
+      - autogenerated & linked documentation of internal modules
+      - integrated with manual written tutorials/notes
+      - crosslinking documentation of experiments with documentation of modules
+        - Web of knowledge
+        - bidirectional discovery of things tried/done in the past to optimize
+          finding of new strategies (meta-optimizing the decisions on what to
+          optimize/try)
+    - Infrastructure
+      - Organized and co-administrated the 4 Root-Servers we had
+      - Set up Kubernetes, Nexus, Docker, Nginx, letsencrypt-certs, dns-entries,
+        etc..
+
+- **Oct. 2018 to Aug. 2021**:
+  - ML-Specialist at [Jobware](https://jobware.de) (Paderborn; german Job-Advertising-Platform)
+    - Extraction/Classification of sentences from JobAds (Requirements, Benefits,
+      Tasks, ...)
+    - Extraction of Information from JobAds (Location of company, Location of
+      workplay, contact-details, application-procedure, etc.) including geocoding
+      of those information (backed by OpenStreetMap)
+    - Embedding of JobAds into a meaningful space (i.e. "get me similar ads. btw.
+      i dislike ad a, b, c").
+    - Analyse & predict search-queries of users on the webpage and offer likely
+      but distinct queries (i.e. similar when typo or complete different words
+      (synonyms, hyponyms, etc.))
+  - Technologies used:
+    - Haskell (currently GHC 8.6, soon GHC 8.8)
+      - stack + stackage-lts
+      - fixplate (recursion-schemes-implementation)
+      - many usual technologies like lens, http-simple, mtl, ..
+      - golden-testing via tasty
+      - several inhouse-developments:
+        - templating based on text-replacement via generics (fieldname in
+          Template-Type == variable replaced in template)
+        - activeMQ/Kibana-bridge for logging via hs-stomp
+        - generic internal logging-framework
+    - Python
+      - tensorflow
+      - pytorch
+      - sklearn
+      - nltk
+
+- **2013-2018**:
+  - several jobs at my University including
+    - Worked 6 Months in the Workgroup "Theoretical Computer Science" on migrating
+      algorithms to **CUDA**
+    - Tutor "Introduction to Machine Learning"
+      - Was awarded **Tutoring-Award** of the Faculty of Technology for excellent
+        tutoring
+    - Lecture "[[FFPiH|Intermediate Functional Programming in Haskell]]"
+      - Originally developed as student-project in cooperation with Jonas Betzendahl
+      - First held in Summer 2015
+      - Due to high demand held again in Summer 2016 and 2017
+      - Was awarded **Lecturer-Award** "silver Chalk" in 2016
+        - First time that this award was given to students
+        - Many lecturers at our faculty never get any teaching-award until retirement
+    - Development of Pandoc-Filters for effective **generation of lecture-slides**
+      for Mario Botsch (Leader "Workgroup Computer Graphics") using Pandoc & reveal.js
+      - Framework: [https://github.com/mbotsch/revealSlides](https://github.com/mbotsch/revealSlides)
+      - Example: [https://github.com/mbotsch/eLearning](https://github.com/mbotsch/eLearning)
