Experienced Big Data Engineer, SQL Developer

Available
As an illustration of my work, I optimized a critical workflow by migrating it from Python to the high-performance Trino (formerly Presto) SQL Engine for Big Data. This transition resulted in a remarkable decrease in execution time, plummeting from 2 hours and 40 minutes to just 6 minutes - a productivity increase of approximately 96.25%. This significant improvement was attributed to the superior parallel data processing capabilities of the Presto engine (MPP). The remarkable outcome not only accelerated information processing but also led to considerable cost savings for the client. This accomplishment showcases my ability to optimize processes and effectively utilize cutting-edge technologies, resulting in tangible and beneficial outcomes.
