Freelancer profile translated to English.

Description

I help SMEs and startups build, fix, and scale reliable data systems. My goal: for your teams to have blind confidence in their data to make the right decisions.

I work on the creation of data pipelines, backend systems, and reporting foundations — from stabilizing existing ETL flows to creating new production solutions in Python and on the Cloud (GCP).

What I deliver concretely:

Robust and maintainable data pipelines (batch or near real-time).

Performant backend processing systems in Python and SQL.

Optimization, monitoring, and troubleshooting of your existing databases (e.g., PostgreSQL).

Clear documentation and smooth skills transfer for your internal teams.

My work method:

Defined scope and realistic deadlines (systematic quotes and specifications).

Pragmatic, business-oriented solutions.

Regular communication and total transparency.

Immediately available for short assignments (audits, pipeline unblocking) or part-time. Ideal for teams that need quick and reliable data support without engaging in a long recruitment process.
