About Me

Hello, my name is Mindaugas Lukošius. I’m huge fan of Software Development (SDLC), software architecture designs. process design, data models and good challenging spirit in the team.

I touched many areas in Software Development, but most of time spent in Business Intelligence, Data Integration (ETL), Data Warehouse areas. Now learning Python and drifting towards current days industry demands.

This is my professional page where I dump my ideas, knowledge and thoughts. It is not polished and may look incomplete.
