Hi, I'm Márton 👋

Focused on econometrics, algorithm design, high-performance software systems and many more.

Focus Areas

  • Quantitative modeling & econometrics (regression, threshold models, statistical inference)
  • Algorithm design & optimization under constraints
  • High-performance systems programming (C/C++, concurrency, Linux)
  • Data engineering & backend systems

Selected Work

📊 Quantitative Modeling

Credit Risk Modeling (Python) Applied machine learning to credit risk modeling by predicting loan defaults from historical lending data and comparing logistic regression and XGBoost performance.

Threshold Regression Model (R) Panel threshold analysis of housing price effects on consumption in Spain. Focus on regime-dependent relationships and nonlinear effects in macroeconomic data.

⚙️ Algorithms & Optimization

Ford-Johnson Sorting Algorithm (C++) Implementation of Merge-Insertion sort with emphasis on comparison minimization and algorithmic efficiency.

Push_swap (C) Sorting under strict operation constraints; optimized move sequences and stack manipulation strategies.

🧠 Systems Programming

Minishell (C) Unix-like shell with parsing, process execution, piping, and signal handling.

Philosophers (C) Concurrency simulation using threads, mutexes, and deadlock avoidance strategies.

🕹️ Graphics / Systems

Cub3D (C++) Raycasting engine with texture mapping and real-time rendering pipeline.

🌐 Full-stack

Ft_transcendence (Next.js) Real-time multiplayer poker platform with backend + frontend integration.

Technical Stack

Python · SQL · PostgreSQL · R · C · C++ · Docker · Linux · Bash · Next.js · Julia
