Business Intelligence Consultant
Full-Stack development: TurboVault
Further extension of the tool for new features such as reference tables
Development of a Domain Specific Language (DSL)
Optimization of the user interaction with the Raw DataVault for the data cleansing purpose by definition of a new programming language and specific Grammar
Developing a new PHP plugin
Developed a plugin that enables querying tables from Google BigQuery directly on DokuWiki pages
Automated cleansing of various Data Vault objects
Data cleansing consists of data extraction from the schemas with a certain pattern, cleansing in Python, and writing them back in a new business satellite
Automated detection of bad-quality data
Primary focus on the Postal code, country ISO codes, and country names
Multi-threaded tool for faster processing
Batch processing for scalability
Extending internal Enterprise Data Warehouse in Google BigQuery
Adding new source systems to the EDW on BigQuery
Extending the Data Vault Model with new data (modeling)
Automated loading of the Raw Vault layer using DBT
Staging of new cloud application (Flexopus + Flipping book)
Creating Taps or extractors with the help of Singer and Meltano for automatic batch loading from both rest APIs
Adding data as JSON files to the available Data Lake on AWS S3
Development of a dashboarding tool for the system performance evaluation and automatic delivery of the results using a mailing library in Python
Simulation tool
Creation of virtual feedback to simulate the Robot?s behaviors, in order to predict Deadlocks and racing conditions. Moreover, possible optimizations by introducing new algorithms could be tested
Legacy code maintenance
Maintenance of the legacy C++ application in the QT environment
Dependency maintenance using Conan recipes and Cmake Feature development for the application

Stereo Visual Odometry / Hydromapper
Software Developer
Software Developer
Stereo Visual Odometry:
The project started from scratch as research and development and I was alone in it. The idea was to derive the trajectory of a moving platform in MATLAB using a pair of cameras. It consisted of
Matlab code for the camera calibration
Matlab code for feature matching and extraction
Data acquisition using hardware triggering (signals were programmed by me in Labjack)
Sensor calibration Arranging test scenarios
Comparing the results against the laser tracker
Making documentation for the system
Hydromapper:
A big project between the Leibniz University, the government of Germany, and a number of private companies including DHPI to detect and monitor the deformations in a water channel using a multi-sensor system mounted on a ship
Integrity tests needed to be done between sensors, therefore, a tool for evaluation of the datasets from all sensors in an automatic manner was required, which I implemented
