Project history
Main responsibilities:
Django/Python: Webshop Price Import Service
In the newly founded System Integration Team, I was able to take on a leading role in the planning and development of the service thanks to my knowledge of Django. The Price Import Service is the central source of all prices. Individual price lists are imported, approved, and made available.
Stack: Django, Ansible, UI/UX, JavaScript
FastAPI/Python: Mentoring
I had the opportunity to help a very dedicated colleague get acquainted with Python and take over the project independently. By setting the direction while adhering to best practices and design patterns, we implemented requirements from stakeholders.
Stack: FastAPI, Unit Tests, E2E Tests, Clean Code, Rest API
Python: One Customer View
As the Lead Developer, I developed a tool that imports millions of customer data daily, scans for doublets, and exports the results in various formats to ensure a correct migration across all systems.
Stack: Python, SQLAlchemy, Alembic, Docker, Jenkins, Ansible, Opentelemetry
- Guiding junior developers
- Finding technical implementations for business requirements
