Position

TL;DR
Python backend developer with a strong foundation in Linux systems and a focus on API design, service architecture, and automation. I am looking for projects with the following content:

Python backend development (FastAPI, Typer, SQLAlchemy, Pydantic)

  • API design: OpenAPI, REST, GraphQL, async APIs
  • Auth: OAuth2, Single Sign-On (SSO)
  • Microservices & Messaging: RabbitMQ, Celery
  • CI/CD & Deployment: Docker, Kubernetes, Helm, OpenShift, Ansible
  • Testing & Quality: pytest, unittest, contract testing
  • ETL pipelines: Dagster, parsing, transformation


Bonus: Experience in data science/ML workflows (numpy, pandas, scikit-learn, keras), mainly through volunteer projects and prototyping.

About me:
I am a backend software developer specializing in Python on Linux, with a passion for API design, robust architectures, and developer tools.

My professional career began in Linux systems engineering, where I developed reliable infrastructures and internal tools. Since then, I have transitioned to backend development, providing Python-based services with REST APIs, messaging systems, and containerized deployments.

My stack primarily includes FastAPI, SQLAlchemy, Docker, and Kubernetes, and I am familiar with integrating databases, queues, and external services.
I am particularly interested in tasks involving API-first development, developer platforms, and automation-heavy backends.

While backend and architecture are my main focus, I have practical experience in data engineering and machine learning workflows and can contribute to data-heavy pipelines or prototype models as needed.

Über mich:

Ich bin ein Backend-Softwareentwickler, spezialisiert auf Python unter Linux, mit einer Leidenschaft für API-Design, robuste Architekturen und Entwickler-Tools.

Mein beruflicher Werdegang begann in der Linux-Systemtechnik, wo ich zuverlässige Infrastrukturen und interne Tools entwickelt habe. Seitdem bin ich zur Backend-Entwicklung übergegangen und stelle Python-basierte Dienste mit REST-APIs, Messaging-Systemen und containerisierten Bereitstellungen bereit.
Mein Stack umfasst hauptsächlich FastAPI, SQLAlchemy, Docker und Kubernetes, und ich bin mit der Integration von Datenbanken, Warteschlangen und externen Diensten vertraut.
Ich interessiere mich besonders für Aufgaben, die API-First-Entwicklung, Entwicklerplattformen und automatisierungslastige Backends beinhalten.
Während Backend und Architektur mein Hauptaugenmerk sind, habe ich praktische Erfahrung in Data Engineering und Machine Learning Workflows und kann bei Bedarf zu datenlastigen Pipelines oder Prototypmodellen beitragen.
