I've started with old good c++, worked within computer vision and gpu programming before mass adoption of neural nets,
went through wonderland of enterprise Java towards functional programming via Scala and then dive in BigData and distribute computing via Spark, falling in love with python with some ML between.
My current specialisations are building effcient data products and performance tuning (system and processes wise)
Team topology, product mindset, extreme ownership, KISS, YAGNI,More...
