Description

Senior Python developer specialized in backend APIs, data pipelines, and automation systems.

I help companies build, improve, and maintain Python services using FastAPI, Django, Flask, PostgreSQL, Redis, Celery, and Docker.

My typical missions include backend API development, ETL workflows, business process automation, integrations, and production performance improvements. I also help modernize legacy applications and make Python systems more reliable in production.

I have strong experience in real-time, trading, and energy environments, but I also work on more general backend and data-driven projects.

Core stack: Python, FastAPI, Django, Flask, PostgreSQL, Redis, Celery, Docker.

Also used: Airflow, Pandas, AWS, Azure, Kubernetes.

I’m a strong fit if your team needs to:

ship backend features without compromising reliability
handle real-time or high-volume data flows
reduce production issues and firefighting
build systems that are easier to maintain and scale over time

Available for remote missions in EU/UK time zones.

Feel free to get in touch if you need a Python developer for backend services, APIs, ETL pipelines, or automation.
