About Gickel

⭐⭐⭐⭐⭐ Python Developer | Data Engineering & Backend APIs

Python Developer with 3 years of experience, I work across the entire data chain: from raw data collection to production APIs.

My core business: designing robust ETL pipelines (scraping, Pandas transformation, PostgreSQL/MongoDB loading), orchestrating workflows with Apache Airflow, and exposing data via production-ready REST APIs (FastAPI, Django/DRF) with JWT/OAuth2 auth, pagination, and rate limiting.

I also master async architecture (Celery + Redis), Docker deployment, and CI/CD automation with GitHub Actions.

My recent projects cover e-commerce price tracking, drug comparison, and real estate data — all open source, documented, and deployed.

Main Stack: Python · FastAPI · Django · Airflow · Pandas · PostgreSQL · MongoDB · Celery · Redis · Docker.

⭐ Data Engineer ⭐ Python ⭐ FastAPI ⭐ Django ⭐ ETL Pipeline ⭐ Apache Airflow ⭐

Very good experience with Gickel for this first phase. He delivered a solid, well-thought-out and documented base, while remaining attentive to the needs and adjustments requested. His way of structuring the project gives confidence for the future, especially for the next development phases. I will continue the collaboration with him without hesitation.
