Hi, my name is

Fabian Hernandez Flores

Computer Engineer · Embedded Systems · Robotics & AI

I am a computer engineer focused on embedded systems, autonomous robotics, and AI. I work across the hardware-software stack, from microcontroller firmware and custom PCB design to reinforcement learning for multi-agent systems. I enjoy learning new technologies and applying them to practical engineering problems.

Graduate Researcher @ Multiple Autonomous Robot System Research Lab

Dec 2024 — May 2026

Conducted thesis research on collaborative autonomous driving, integrating camera, LiDAR, GPS, and radar sensor data with reinforcement learning and Control Barrier Functions.
Contributed to LLM-Foraging in Gazebo, using OpenAI GPT-5 mini as a low-cost reasoning agent for decentralized tactical decisions in CPFA-based swarm robot foraging.
Trained and evaluated centralized and decentralized PPO policies for swarm foraging in Webots using Deepbots, PyTorch, and Stable-Baselines3 to improve performance over the CPFA baseline.
Developed and tested autonomous workflows using ROS 2 Jazzy, Gazebo Harmonic, ArduPilot SITL, MAVROS, and Python/C++ for simulation-to-hardware drone control.
Assisted in building a low-cost autonomous drone platform with a Raspberry Pi 4, selected electronic components, custom batteries, and 3D-printed modular mounts.
