About

I hold a degree in Video Games Development from Universidad Complutense de Madrid. I have professional experience working with HISPlayer, NexPlayer and Labotec Games.

Additionally, I gained extensive experience working on different projects during my college years. These are some of the most notable projects I worked on: DoppleBanger, Papagayo Games, CoreWar UCM, Towertido, Goblin Slayer and Automatic Learning Project.

In both professional and academic fields, I have demonstrated a proven track record of developing quality code to solve different tasks and problems. I have also shown my ability to work in different teams, initiative, enthusiasm, social skills and leadership.

Overall, I particularly emphasize my strengths in solving problems and project coordination and management, as well as my ability to conduct large- or small-scale analysis. This includes developing ideas and tackling the next small task that arises in the roadmap. I consider it highly important to first think about how to approach the upcoming work.

Experience

Junior Software Engineer

HISPlayer and NexPlayer
Oct 2022 - Sep 2024

HISPlayer is a multi-platform video streaming SDK for Unity and Unreal Engine, providing smooth integration for high-quality video playback across multiple devices and operating systems.

I primarily developed for Unity, focusing on Android, iOS, macOS, and visionOS platforms. Additionally, I contributed to the development and maintenance of other platforms, including WebGL, Windows Standalone + UWP and Unreal for Android. My responsibilities included integrating native plugins, ensuring performance optimization, and maintaining platform compatibility.

I also worked on code obfuscation, packaging, sampling, and QA processes.

In addition to my technical expertise, I excel in teamwork, communication and customer support. I worked closely with colleagues and clients, adapting to their needs and continuously improving documentation and guides to facilitate the seamless integration of the SDK in Unity and Unreal.

Video Games Programmer - Unity

Labotec Games
Sep 2021 - Nov 2021

I worked as an intern for three months, contributing to the development of two video games using Unity.

I was primarily engaged in the mobile game project, an endless runner where the player controls a car using eye-tracking technology to dodge obstacles. I specialized in developing the eye-tracking system, its calibration, and the user interface, focusing on usability and logic.

The second project, an FPS shooter, was in an early stage, where I worked on TCP/IP and UDP protocols.

I also collaborated with artists and designers, enhancing my teamwork and communication skills. We followed the Scrum methodology, with daily in-person meetings to plan tasks and discuss project aspects.

Body Performance Classification

Jan 2022

The project aims to evaluate machine learning algorithms for optimal dataset classification.

The dataset consists of 13,393 samples, each representing an individual with 11 attributes related to physical characteristics and performance. The data forms a (13,393, 12) matrix.

The last column indicates the fitness training rating (A, B, C, or D), with A being the best score.

Algorithms used: SVM, Logistic Regression, and Neural Networks
