At Alcyon Photonics, I developed a comprehensive testing pipeline for design layouts, enhancing the efficiency and accuracy of our processes. Additionally, I contribute to circuit tapeouts, utilizing tools such as Optocompiler, IPKISS, and Lumerical for advanced circuit design and simulation.

In my initial project at Kenmei, I led the design of a dashboard to monitor radio network metrics concerning energy consumption and savings, while also detecting inconsistencies or malfunctions. Leveraging Looker Studio, I developed the dashboard, with data provided periodically through an Apache Airflow job. To manage the substantial data volumes, I utilized Pyspark, BigQuery, and PostgreSQL.Additionally, I contributed to a generative AI project involving a bot assistant tasked with retrieving information from internal databases via Microsoft Teams. My responsibilities included enhancing the model's accuracy by programming an internal testing tool, enabling it to handle multiple queries and user stops simultaneously through multiprocessing, and refining its performance via prompt engineering and the creation of auxiliary agents to ensure clarity when querying databases.After that, I simulated a setup to localize objects within a standalone 5G network by merging signaling traces with prior fingerprinting measurements. This involved utilizing the Eclipse Mosquitto MQTT library for handling both data sources, and Pandas for merging them effectively.Lastly, I helped out developing a geolocation algorithm using mobile networks' signalling traces and propagation models through PostGIS.

Member of 'Photonics Research Labs' research group (PRL), within the Institute of Telecommunications and Multimedia Applications (ITEAM) at the Polytechnic University of Valencia (UPV). During that time, I obtained a PhD in Telecommunication Engineering.My initial research focused on the automated synthesis of optical filters on integrated photonic waveguide meshes using mixture density networks. The findings of this investigation were published in my Master's Thesis at the Polytechnic University of Madrid (UPM) in 2019. During this phase, I gained lab expertise in optical set-ups with horizontal and vertical alignment.Subsequently, we explored first-order optimization techniques such as single gradient descent (SGD), SGD with momentum, RMSprop, ADAM, etc., to address this challenge. This methodology was presented at the Conference of Lasers and Electro Optics in 2020 and further elaborated in a Nature Communications article published the same year. Additionally, I contributed to the layout design of the first prototype of a general-purpose photonic processor using Synopsis Optodesigner and simulated its optical components using Proton Design. This design laid the foundation for today's first commercial product, offering a wide range of microwave photonic applications, as outlined in a second Nature Communications article in 2024.During this period, we also devised an alternative method for programming photonic circuits on waveguide meshes based on graph theory with bidirectional search. This approach was initially proposed in an Optics Express article (2020) and later extended to include the simulation of these structures in a subsequent article in the Journal of Lightwave Technology (2022).In the final stage of my thesis, I contributed to the design of automated software routines for rapid checks on the status of optical components in these devices. Results were presented at the IEEE Photonics Conference in 2022 and during my thesis dissertation in 2023.

As a professor at the university during a teaching semester, I assumed the sole responsibility for instructing a laboratory course attended by 25 second-year Physics students. This course encompassed experiments spanning mechanics, thermodynamics, and optics. Throughout the semester, my role involved guiding students through practical measurements in the laboratory, overseeing data collection, and assisting them in translating their findings into comprehensive written reports. Additionally, students were tasked with selecting and presenting one of the experiments they conducted to their peers, who actively participated in a peer-review process. To evaluate their comprehension and mastery of the subject matter, students were required to successfully pass a final examination. Throughout the semester, I provided mentorship, support, and feedback, resulting in highly positive critiques from the students.

Collaboration scholarship in the Department of Signals, Systems and Radiocommunication (SSR), within Data Processing and Simulation Group (GPDS).During that time, I was in charge of piloting an unmanned aerial vehicle (DJI Phantom drone) through software written on C++ to make it land on specified landmarks recognizable through OpenCV library.

During my one-year internship at Telefonica gCTO in Distrito Telefonica, I was responsible for analyzing throughput and power consumption data of mobile devices from various countries, categorized by model. I conducted ANOVA tests to extract significant insights from the data. Additionally, I facilitated meetings with mobile vendors twice a year to gather updates, which I subsequently summarized in reports. Furthermore, I conducted experiments in the laboratory to evaluate device performance and categorize them by vendor, involving measurements of signaling and throughput traces as well as power consumption analysis.
