Evolution
During the global health crisis, Sercan Kilinc, the director of SKB Group, had a vision to create EXPOPRÜF- a solution aimed at simplifying public health data analysis in Germany.
EXPOPRÜF: RevolutionizingHealth Data Analysis
Sercan's dream was simple: to bid farewell to the laborious days of manual Excel sheet analysis. He envisioned a system that could deliver results at lightning speed, making the fight against diseases like COVID-19 more accessible and efficient.
Here's a detailed breakdown
of how it works:
Initial Data Collection
Users begin by uploading two distinct Excel files onto the web app:
File 1: An Excel sheet filled with handwritten data, meticulously prepared by the company.
File 2: A software-generated Excel sheet, automatically generated by the company's website, based on the specific month and year selected by the user.
Data Entry
Once the files are uploaded, the user proceeds to fill out several requisite entries capturing crucial data that aids in generating the desired reports. These entries include:
Monthly Overview: The total number of cases that have occurred in each month.
Monthly Breakdown: A detailed view indicating the number of cases specific to each day of the month.
Test Reason Breakdown: Data related to the number of cases categorized based on the reason for testing, specified for each day.
Operational Hours: The exact arrival and departure times of the company and the clinic where the final Excel report is issued.
Month Specification: The user must indicate the month for which they are generating the report, e.g., January, February, etc.
Report Generation
After diligently filling out all the necessary entries, the user simply clicks on the "Download" button. This action triggers the production of two critical documents:
1. A comprehensive report detailing the above-mentioned data.
2. Medical certificates pertinent to the patients.

To address these challenges effectively, the project plan included a dedicated phase for extensive research and development. This allowed the team to explore solutions, test different approaches, and refine the platform's functionalities.
Tech Foundations
Unified Platform
Now, let's talk tech. We picked the right tools for the job. Flask for the backend, HTML, CSS, JavaScript, Bootstrap for the front end, and Python as the glue holding it all together.
Flask for the Backend
Flask was the foundation for our application. We divided it into two Flask-based microservices. One handled Excel data processing and validation, while the other focused on generating certificates. Both worked smoothly in a microservices setup, ensuring our platform runs efficiently and reliably.
But why Flask over any other framework?
Flask's Simplicity
Flask is a lightweight and minimalistic framework, that perfectly aligned with EXPOPRÜF goal to generate PDF certificates without the complexities of a full-scale web framework.
Keeping It Simple
Compared to other frameworks, Flask keeps things simple. That means our code could focus solely on making PDFs, without getting tangled up in unnecessary stuff.
Picking and Choosing
Flask gave us the freedom to choose what we needed. We could pick libraries like ReportLab or WeasyPrint for making PDFs, tailoring our PDF system just the way we wanted it.
Thinking About Project Size
Framework like Django can be a time-saver for smaller projects. It has lots of things already built-in. But EXPOPRÜF demanded breaking things into smaller parts, and Flask helped us with that too.
HTML, CSS, JavaScript, Bootstrap for the Frontend
HTML (HyperText Markup Language)
HTML was the backbone of web development. It was used for structuring the content of web pages. HTML was used to define the layout and structure of the user interface.
CSS (Cascading Style Sheets)
CSS was essential for styling. It defined how the content was being presented, including aspects like fonts, colors, spacing, and layout. For a user-friendly and visually appealing interface, CSS played a crucial role.
JavaScript
JavaScript, the versatile programming language, added interactivity and dynamic behavior. It was used for tasks like form validation, real-time updates, and user interactions
