Computer Engineering · Seville, Spain
I build across hardware, firmware and application software: custom PCBs, embedded C, Linux systems, real-time links, edge AI and the tools around them. The useful work is usually where those layers meet.
Selected work
Not a list of technologies. Each project starts with a problem, makes trade-offs, and records what has actually been validated.
A distributed road-safety prototype that detects emergency-vehicle sirens, estimates their direction, and gives the driver a visual and spoken warning. One roof ESP32-S3 captures four microphones; a cabin ESP32 and Raspberry Pi handle alerts, sensors, logging and the interface.
A real-time system for playing online with physical backgammon boards. Phone cameras feed a FastAPI and WebSocket backend; OpenCV and YOLO read the board and dice, while an authoritative rules engine repairs ambiguous vision output or asks for one-tap confirmation.
A dual-MCU, multi-radio security-research handheld. The design package and firmware are complete; physical bring-up and the custom PCB are still pending. Offensive and illegal radio functions are deliberately excluded.
An eight-page Raspberry Pi 5 in-car interface combining offline navigation, OBD-II gauges, media control, cameras, system diagnostics and SirenSense safety alerts. The software is complete; Pi 5 and in-car validation remain.
A universal magnetic e-paper display for the back of a phone, designed around an nRF52840, BLE uploads and partial-refresh animation. Power budget, protocol, BOM and staged validation plan are documented; no finished hardware is claimed.
An ESP32 system publishing temperature and humidity to a Java/Vert.x backend and controlling a relay-driven fog machine used to simulate an alarm procedure. Includes timed activation, cooldown, reconnect handling and documented security limits.
Desktop and developer tools including a Python dark-mode PDF viewer, structured media-library utility, data-processing scripts, test harnesses and documentation tools built to solve problems encountered during larger projects.
Capabilities
I am strongest when a fault crosses boundaries: noisy power becomes bad samples, a packet looks successful but disappears, or a camera result disagrees with the application state.
KiCad schematics and boards, component selection, LiFePO₄/LiPo protection and charging, DC/DC conversion, filtering, decoupling, ferrite beads and bring-up.
ESP32, STM32, FreeRTOS, drivers, GPIO, I²C, SPI, UART, I²S, state machines and defensive failure handling.
Raspberry Pi, systemd, device interfaces, Caddy, HTTPS, logs and deployment-oriented troubleshooting.
MQTT, WebSockets, REST, ESP-NOW, LoRa, BLE, JSON protocols, FastAPI, Vert.x and SQL.
OpenCV, YOLO, Edge Impulse, MFE classifiers, GCC-PHAT direction finding and measurement-aware validation.
About
I am a Computer Engineer based in Seville, working across embedded systems and software. I enjoy following a problem through the complete system instead of treating hardware, networking and applications as separate worlds.
SirenSense is the clearest example: custom power and microphone hardware, firmware on multiple controllers, wireless links, a Linux interface, computer vision and a physical enclosure, all debugged as one product.
Available for engineering opportunities
I am interested in embedded, systems integration, customer engineering and technical roles where practical investigation and clear communication both matter.
