Hi, I'm Rafael Salcedo

Machine Learning & AI Engineer in training

LinkedIn Email Location

I build applied AI systems that connect models to real devices, software and operational problems. My work spans humanoid-robot decision policies, embedded computer vision, multimodal sensor fusion, data analysis and AI infrastructure.

I am a Computer Engineering student at Universidad de La Sabana with an IoT concentration and graduate-level coterminal coursework in Artificial Intelligence. I also work on AI/software solutions and contribute to reinforcement-learning research for the Sabana Herons humanoid robotics team.

Selected work

Project My contribution Core stack
Sabana Herons 2026 · team collaboration Integrated role-conditioned RL policies into the C++ robot stack through ONNX; worked on the observation bridge, SimRobot scenarios, ball perception and HSL match behavior deployed for RoboCup 2026 C++, Python, PPO, ONNX, SimRobot, YOLO, humanoid robotics
AIoT Posture & Fatigue Monitor · team lead Developed two TinyML vision models and fused their output with MPU6050 inertial signals on an ESP32-S3; reported 199-222 ms embedded classification latency TinyML, MobileNetV2, ESP32-S3, Edge Impulse, MQTT
Construction Safety PPE Detection · collaboration Added the YOLO object-detection workflow, Colab execution and model-sharing documentation for detecting PPE compliance and visible violations Python, YOLOv8, computer vision, Gradio, Jupyter
Paddle Tournament Predictor · collaboration Contributed to the EDA, feature pipeline, logistic-regression ranking and functional match/tournament simulation exposed through Streamlit Python, scikit-learn, Streamlit, feature engineering
Resil-IA · team collaboration Co-developed a geospatial flood-risk prototype with an interactive map, community features and an n8n RAG assistant React, Node.js, Leaflet, GeoJSON, n8n
Connect4RL · collaboration Built the initial Connect Four environment, policy interface, dynamic policy discovery and tournament runner; the project evolved with Fermin Escalona's MCTS variants, timing controls and final policy Python, MCTS, UCB1, Monte Carlo methods
