AutoGOAL - Meta-Learning Extension
A meta-learning subsystem for AutoGOAL, an open-source AutoML framework: it learns from past experiments to predict which ML pipelines will do well on a new dataset, before training anything.

PROJECTS
DATA · SCIENCE
github ↗
Crypto Market Analysis Dashboard
An interactive dashboard for cryptocurrency markets, joining technical indicators computed from live price data with sentiment analysis of Twitter activity.
ML · NLP
github ↗
Negation Detection in Spanish Text
An NLP system that detects negation in Spanish text: it finds the words that express negation and works out which parts of the sentence they affect.
COMPILERS
github ↗
COOL Compiler to MIPS
A complete compiler for COOL, a statically-typed object-oriented language, from source code to runnable MIPS assembly through all four classic phases: lexing, parsing, semantic analysis, and code generation.
TOOLING
github ↗
Claude Sync
A desktop app that keeps MCP server configurations in sync between Claude Desktop and Claude Code, with care for the mess of running both across Windows and WSL.
WEB
University Enrollment Management System
A web app that automates enrollment for the University of Havana's distance education programs, from applicant registration through entrance exams to major assignment.
TEACHING
github ↗
Machine Learning Practical Classes
Hands-on Jupyter notebooks made for teaching machine learning at the university: practical sessions where students learn the algorithms by using them.
SYSTEMS
github ↗
Airport Discrete-Event Simulation
A discrete-event simulation of a week of airport operations, estimating runway idle time under scheduled flights, random arrivals, maintenance, and weather.
SYSTEMS
github ↗
S-MIPSv2 Processor in Logisim
A 32-bit MIPS-style processor built gate by gate in Logisim: register file, ALU, control unit, and split instruction/data caches, verified by running real assembly programs on it.
ML
github ↗
Schizophrenia Classification from Brain Signals
A machine learning study on telling schizophrenic patients from healthy controls using EEG brain responses, with wavelet-based feature extraction and SVM classification.
ALGORITHMS
github ↗
Design and Analysis of Algorithms
Four optimization problems, each solved several ways (dynamic programming, backtracking, divide and conquer, greedy) with a complexity analysis of every attempt.
SYSTEMS
github ↗
CPU Scheduler Simulator
A simulator of how operating systems share the processor between competing jobs, with four classic scheduling algorithms and a comparison of their performance.
ML · NLP
github ↗
Information Retrieval System
A search engine built from scratch on the vector space model: documents and queries become weighted vectors, ranked by similarity, with clustering, a web crawler, and evaluation on standard test collections.
AI
github ↗
Fuzzy Inference System
A fuzzy logic engine built from scratch that reasons with imprecise concepts like 'near' or 'hot', covering the full pipeline from fuzzification to defuzzification.
DATA · ENGINEERING
github ↗
SensorTower App Market Scraper
A data collection tool that gathers mobile app market statistics from SensorTower: rankings, downloads, and pricing for the top apps across countries and categories.
WEB
github ↗
Tic-Tac-Toe, Framework by Framework
The same game built independently in different frontend stacks, React on one side and Python's FastHTML with HTMX on the other, as a small, comparable playground for trying frameworks.
COMPILERS
github ↗
Type Inference for COOL
An interpreter for the COOL programming language extended with automatic type inference: declare a variable as AUTO_TYPE and the system deduces what it must be.
COMPILERS
github ↗
Grammar Analyzer
A web tool that analyzes context-free grammars: it computes their key properties, finds which parser families can handle them, and suggests fixes for problem grammars.
MISC
github ↗
Chat-Block
A proof-of-concept chat channel built on a blockchain: every message becomes a block, so no one can quietly edit the history.
AI
github ↗
Intelligent Agents Simulation
A multi-agent simulation where a robot must keep a house clean while children move around making a mess, testing how reactive agent behavior holds up in a changing environment.

DataCamp Data Science Projects
Hands-on data analysis projects from DataCamp's Data Scientist with Python track: real datasets explored, cleaned, and visualized in Jupyter notebooks.
