Hi, I’m Martin.
I connect the dots.
For more than 16 years, I’ve worked where engineering, data, and business meet. My experience spans operational analytics at Bankers Petroleum Albania and AI evaluation and human data management at micro1.
I hold a Master’s in Petroleum Engineering and am pursuing a PhD. My approach is practical: understand the system, question the assumptions, and build something useful.
