About Kossi Isaac

Mechanical engineer with strong expertise in numerical computing, simulation, and scientific programming, I support companies on high-value-added technical issues, from analysis to the implementation of reliable and efficient tools.

I mainly focus on:

Python development for scientific computing, automation, and data post-processing
Modeling and data/machine learning tools applied to engineering
Numerical simulation / finite elements (Abaqus, SolidWorks Simulation, Robot)
Data analysis and signal processing (FFT, vibration analysis, physical indicators)

Accustomed to demanding industrial environments, I work with a rigorous, pragmatic, and results-oriented approach: understanding business needs, adapted modeling, clear and usable deliverables.
