GLogWare | Material Flow Controller
https://vimeo.com/295150144Developed and commissioned GLogWare, a material flow controller orchestrating the flow of products within a production plant.
The solution can handle up to 100,000 products simultaneously while giving orders to conveyors and robots. The logic was developed using C#.NET and PL/SQL and comprised multiple Windows services communicating with each other. Staff can observe and interact with the system using a rich client-side application based on WinForms.
I developed this whole solution together with my teammate. The requirements differed for each plant, meaning parts of the application were project-specific. For a leading tire manufacturer, I took the lead in developing and commissioning the solution for a plant in Thailand. The commissioning onsite was done in close collaboration with the customer's IT department and the plant's staff.
The solution enabled them to efficiently manage the handling of over 250 different kinds of tires.

Automated AliExpress Product Price and Availability Tracking
Developed an automated system for a dropshipping website to keep track of prices and availabilities for relevant AliExpress products.
The system kept track of every individual price and availability for each combination of product options, e.g., a USB cable might have different lengths and color options, each with individual availability and prices.
The final product consists of the following:
• A regularly executed Python script implementing the Scrapy framework to fetch all the necessary information from all products being tracked.
• A MySQL server to store the current and historical prices and track product availabilities.
• A JavaScript scriptlet for admins to easily add new AliExpress products to the tracking pool.
The product was running as a service on a Linux server, and the whole package was deployed on a LAMP server using Docker.

Parameters, calculations, and results can all be downloaded as a PDF file.
REST API for a Quiz Platform
Developed a REST API for a quiz platform using Python, handling up to 100,000 quizzes. The technologies used were FastAPI, Pydantic, and OAuth2. Logged-in users can participate in quizzes made by others and create, edit, and evaluate their quizzes.
API FEATURES
• Registration/log in using an email and password.
• User login state is verified using OAuth 2.0 with a JWT Web Token.
• Every user can create up to 10 quizzes and add, edit, or delete questions and their possible answers.
• Users can publish their quizzes and make them available for other users to be filled out. After publication, they can't be edited anymore, only deleted.
• Other users can search for quizzes in a list of available quizzes.
• Queries would return a high number of rows and have pagination enabled to ensure the system's performance. A start offset and the number of returned rows must be specified for each request.
• Deleted quizzes are only flagged as deleted to enable recovery.
• Quiz owners can calculate the average correctness of all submissions.
The framework can easily be tested using Uvicorn and Swagger UI, which is built into FastAPI by a default API.

Licensing Server
Built a licensing server from scratch using Python and MySQL. The server is used to handle the licensing of various company-developed products.
It was deployed on Google Cloud and made accessible through Google Cloud Functions using Google's SSO. The framework used to access the MySQL server was SQLAlchemy.
A lot of effort went into security, ensuring all connections are encrypted using state-of-the-art technologies and encrypting the data stored on the MySQL server.

OCR Service to Recognize Current Prices at Gas Stations
Developed an OCR-Service based on Google's Vision API.
The service takes pictures uploaded by the community to recognize current gas prices at gas stations. The service was made for an app that guides users to the closest and cheapest gas stations. In order for the gas prices to stay up-to-date, the community can upload pictures of the gas prices and earn points.
The OCR-Service had a recognition rate above 95%, which is quite high considering the wide variety of ways how gas prices are displayed.
If the prices are not recognized by the OCR-Service, users can enter them manually.
