Started coding 20 years ago. Have past experience in Java, C++, JavaScript/HTML.
My focus is on quick development and optimal/fast working code.

In the passed I was doing research time series analysis in Matlab (FFT, MAtching Pursuit, audio signals)

Currently, daily I do SQL optimization in fintech company (making SQL faster + indexing) / mainly Postgres.
I worked with tables up to 10 billion rows so we can call it big data I think.

SQL often combined with Python 3 for ETL jobs.
Python data processing and whatever needed. Did some cython too.

Occasionally Excel reporting and presentations.
Have some experience in PowerBI and Metabase.
