Machine Learning Engineer

Sener

Tres Cantos, Madrid

Machine Learning Engineer, vision algorithms development for autonomous vehicle and leadership in RAG system to obtain documentation information

Responsibilities

Development of the set of vision algorithms for autonomous vehicle.
Leadership in the development of RAG system to obtain documentation information.

Key Accomplishments

When working on an autonomous vehicle everything has to go on an embedded device, which is not as powerful as a normal computer. So I optimized the neural networks with TensorRT, making the inference time and the necessary VRAM memory much lower, ensuring the real-time operation of the autonomous vehicle.
Development of a dataset of realistic synthetic images to train the networks for the autonomous vehicle, creating images in different environmental conditions, making the neural networks more robust.
Implementation of startup scripts for all the libraries and programs of the autonomous vehicle device. Before only one person knew how to install everything, now anyone can start the system.

Arquimea

Leganés, Madrid

AI, HW and FW development.

Responsibilities

Implementation of detection algorithms for UAV.
Development of a pilot algorithm for geopositioning without GPS.
Leadership of UAV HW and FW development.

Key Accomplishments

With the implementation of detection algorithms for UAV, we avoided having to buy a device that did such detection, saving a cost of €2000 per unit.
When I arrived, the HW and FW of each of the UAVs and ground stations was different, which meant that there were several teams developing the same functionality, in different ways. I unified the HW of the UAVs and ground stations, which reduced the cost of PCB manufacturing. It also allowed to create a common low-level FW, having to change only the high-level part, avoiding duplicate developments.
In electronic warfare environments, it is common to disable the GPS, which is lethal for UAVs, as they cannot geoposition. With the pilot algorithm for geopositioning without GPS, we managed to have a competitive advantage against our competitors.

HW and FW development.

Responsibilities

FW development of autonomous helicopter control PCB.
Maintenance of autonomous helicopter PCB HW.
HW development of PCB with sensors for a fighter.

Key Accomplishments

Nobody wanted to take charge of the FW of the autonomous helicopter control PCB, which made the project progress very slowly. I took charge of the FW, so the project progressed much faster.
When I arrived, the startup tests of the PCBs were done by hand, since they were designed by the engineers who designed them and only tested them in the design phase. But when the project was in production, every time new PCBs were manufactured, their tests were very slow because they had to be done by hand. In the PCBs I developed, I implemented test wiring and test FW, so that the test of the PCBs was done automatically, making that when the project was in production, the tests of the PCBs could be done much faster and also could be done by more people, because it was not necessary to have personnel with a certain minimum knowledge.

Tomorrow's Agents: Deciphering the Mysteries of Planning, UX and Memory

AI agents, powered by LLMs, promise to transform applications. But are they simple executors today or future intelligent collaborators? To reach their true potential, we must overcome critical barriers. This talk delves into the three puzzles that will define the next generation of agents: 1. Advanced Planning (The Brain): Today's agents often stumble on complex tasks. We'll explore how, beyond basic function calls, cognitive architectures enable robust plans, anticipation of problems, and deep reasoning. How do we make them think several steps ahead? 2. Revolutionary UX (The Soul): Interacting with an agent cannot be a source of frustration. We'll discuss how to transcend traditional chat toward human-on-the-loop interfaces—collaborative, generative, and accessible UX. How to Design Engaging Experiences? 3. Persistent Memory (The Legacy): An agent that forgets what it's learned is doomed to inefficiency. We'll look at techniques for empowering agents with meaningful memory that goes beyond their history, enabling them to learn and making each interaction smarter. With practical examples, we'll not only understand the magnitude of these challenges, but we'll also take away concrete ideas and a clear vision to help build the agents of tomorrow: smarter, more intuitive, and truly capable. Will you join us on the journey to unravel the next chapter of AI agents?

Use this locally

Hugging Face spaces allow us to run models with very simple demos, but what if the demo breaks? Or if the user deletes it? That's why I've created docker containers with some interesting spaces, to be able to use them locally, whatever happens. In fact, if you click on any project view button, it may take you to a space that doesn't work.
