Trying to have a positive impact in the world šŸ§ šŸ¤–šŸ’„

2025, Feb-Present
Machine learning engineer intern at Spatialise. Worked on the development and improvement of ML models for the prediction of soil organic carbon leveraging satellite data. I mainly worked on improving model accuracy and applied research on graph neural networks.
2024, Jun - Oct
I was a research engineer at the Radio Science Research Lab at the Radio Astronomy Institute. I designed inversion algorithms for the retrieval electron density profiles from a given map of echoes of electromagnetic pulses. I also learned a bit of machine learning in my spare time.
2024, Jan-Mar
I was a software engineer intern at Fromsolvers. I was part of the backend development team for the implementation of a Multiplayer Trivia Game. Some tools I got familiar during those months are Docker, Django, Pydantic, FastAPI.
2022 - 2023
MSc at the Balseiro Institute and Bariloche Atomic Center where I worked with Armando Aligia on modeling the correct response of Majorana zero modes or low-energy eigenstates of a topological superconductor wire when a quantum dot is approached.
2022, Mar-May
UROP at the University of Sao Paulo advised by Yoshiharu Kohayakawa. Investigated quantum communication protocols in which two spatially separated parties could solve a distributed task without any need for classical communication.
2016 - 2021
BSc at the Pontifical Catholic University of Peru with a major in physics and a minor in electronic engineering. This is where I first got coding competitions and wondering how nature works. For my thesis I got to work on holographic entanglement entropy with Pablo Bueno from Barcelona University.

ionogramNET: I partially reproduced the "Ionospheric Echo Detection in Digital Ionograms Using Convolutional Neural Networks" paper [link] in PyTorch to extract the o-mode signal traces from ionograms(a map of echoes of vertically sent electromagnetic pulses).
ICPC REPO is a collection of blogs, problems and resources I found during my journey in competitive programming. I plan to add some solutions of relevat contests in the future.
Final term paper for the open quantum systems course. A diagonalization procedure results in a single, canonical representation of the master equation, which can be used to fully characterize the non-Markovianity of the time evolution.
Final term paper for the class of photonics in microwave system. I designed a Radio-over-Fiber system with three channels, the modulation and demodulation system to recover the original signal that is received at the end of a optical fiber of 20km. The challenge was to obtain the eye diagram correctly. [PDF]
I developed some computational experiments in Mathematica to find casual graphs containing horizons. Wolfram physics models exhibit quite explicitly event horizons through causal graphs. They are defined as a boundary to where the effects of a certain event of our interest can reach.
