Characteristics

Me in 3 points

T-shaped Engineer

Data is my passion and I'm able to work on front-end, back-end and infra allowing me to tackle a broad range of complex real-world problems without extra hire.

Give a damn

Relentless result-driven with a high creativity on solutions. Being idle waiting for an never-coming answer is not in my nature.

Clear Model Builder

Intractable problems find their source in bad models. I'm capable of building them, spotting inconsistencies, understanding interconnections and trade-offs.

Most Notable Creations
