• 💬 Topics I enjoy: data engineering, DevOps, backend architecture and automation

Repositories that best represent my work:

Academic project focused on educational data analysis, including an automated systematic review pipeline (PRISMA) and an experimental workflow for identifying student competencies. The research/ module provides a CLI for literature retrieval and screening, report generation (CSV/HTML/BibTeX), tests, and technical documentation.
Python | Research Automation | Data Analysis | CLI

Backend application developed in Java (Spring Boot) to manage authors, books, users and loan workflows. Implements Spring Data JPA/Hibernate, MySQL, validation layers and the Observer pattern for email notifications. Includes modular structure and Maven execution instructions.
Java | Spring Boot | JPA/Hibernate | MySQL

Collection of notebooks and organized experiments using traditional ML and deep learning (ANN, CNN, RNN, PINNs, SVM, XGBoost). Includes training pipelines, preprocessing, model evaluation and reproducible environments (requirements.txt and environment.yml).
Python | scikit-learn | TensorFlow | ML/DL

Automation, provisioning, server configuration, NGINX setups, deployment standards and containerized services for DevOps practices.
Shell | Linux | NGINX | Docker | DevOps

A set of backend and frontend exercises and small applications (APIs, real-time communication with WebSocket, Dockerized services and prototypes).
JavaScript | Python | Docker | WebSocket

Academic repositories written in C, featuring classic and advanced data structures (e.g., red-black tree) and algorithmic implementations such as external sorting. Demonstrates strong theoretical grounding and low-level programming.
C | Algorithms | Data Structures

Persistence of Vision (POV) display implemented in C++ for a Digital Systems course, exploring timing control, LED sequencing and embedded logic.
C++ | Embedded Systems | Digital Electronics
