About me

I build practical machine learning projects with a focus on tabular modeling, feature engineering, model evaluation, and clean Python/C++ implementation.

My current goal is to become a Machine Learning Engineer who can connect data preparation, model training, validation, and deployment into reproducible engineering workflows.

Machine Learning  →  Feature Engineering  →  Model Evaluation
Algorithms        →  Data Structures       →  Problem Solving
Software Systems  →  Docker / Linux        →  Deployment Basics

Current focus

  • End-to-end ML pipelines
  • Regression modeling and ensemble methods
  • Cross-validation and error analysis
  • C++ data structures and algorithms
  • Docker, Linux, Git, and MLOps fundamentals

Engineering Statement

I believe strong machine learning engineers should understand not only how to use tools, but also the principles behind them.

My goal is to grow into an engineer who can combine programming ability, algorithmic thinking, mathematical foundations, and real-world ML system development.

Always learning. Always building.
