🖥 Projects

At Avid I’m part of Pro Tools, being the Tech Lead of the team for post-production and interoperability, owning new edition features (markers, data import, speech transcription) and expanding our UI framework (including integration with Qt). I also help in the development of internal tools for code quality and testing.

One specific area I’m passionate about is performance profiling and code optimization. Regardless of the work I’m doing, I’m always trying to optimize code around (and not so close). As some specific examples: run-time cache for text rendering (10x), improved marker queries (530x for insertion, 370x for paste, 160x for drawing), RDP thinning algorithms for automation thinning (12x on average, best case 1900x), RadixTrie for property maps (3x) and unique name generation (75x), session import (about 400x of accumulated speed up through several improvements).

In my previous position in the Embedded Team at Wallbox Chargers, I focused on the development of the services running in the chargers, as well as in the refactoring and migration of legacy components into a micro-services architecture. Additionally, I collaborated with the DevOps and QA Teams in improvements on the GitLab pipeline and other automations;

As part of the software engineering team at STT, my work was centered on the development of applications for motion capture, video processing and 3D scanning, as well as in the design of user interfaces for highly demanding desktop software and mobile applications. At CEIT I focused on the research and development of simulators, medical imaging software and training systems;

📀 Other Recent Projects

Projects under NDA are not listed here.

• Cycling 2DMA (previously BikeFit by STT Systems) is a high speed 2D motion capture application for bike fitting, that provides a quick analysis of the rider’s position and dynamic measures. I’m the project manager as well as the developer of user interface (built on Qt), camera acquisition library (PointGrey and IDS), video management (including our own variation of M-JPEG), data analysis and measurement tools. [C++11, Qt5, Boost, PointGrey SDK, OpenCV, XML]. STT, Spain. 2016-2021;
• iSen. I’ve participated in the design and development of the capture workflow, several plug-ins for video-capture and motion analysis, and the sessions database of this motion analysis tool for STT’s IMUs (Inertial Measurement Unit). [C++, Qt5, MFC, Boost, XML, OpenCV, internal libraries]. STT, Spain. 2014-2021;
• Podia Scanner software. Podia is high resolution foot scanner. Podia software comprises all necessary tools to perform accurate measurements. For this, I developed the patients database (see MetaDatabaseUI), the 3D reconstruction module and the measurement tools. Regarding the user interface, I participated in its graphic and interaction design, as well as in its development. [C++11, Qt5, Boost, Eigen, XML, OpenGL 3, GLSL, internal libraries]. STT, Spain. 2013-2021;
• Licentia is a licensing and encryption system to be used by several STT’s products. [C++11, OpenSSL, Qt5, Boost, XML]. STT, Spain, 2014-2021;
• Scanner Central Station is a dynamic and highly flexible plug-in architecture for STT’s scanners. SCS provides both a common and intuitive front end GUI, and a framework for creating the acquisition drivers. [C++11, Qt5, Boost, OpenGL 3, GLSL, internal libraries]. STT, Spain. 2014-2021;
• ScanStudio is a scanning software suite that unifies different scanner drivers (using Scanner Central Station), post-processing tools and a common models database. It uses a plug-in architecture to allow maximum flexibility and provide developers with a common framework to reduce the development time and guarantee a great integration. ScanStudio is the environment upon which the software of STT’s scanners is built. [C++11, Qt5, Boost, internal libraries]. STT, Spain. 2014-2021;
• MeshProcessingLib is a library that provides high-level data structures and algorithms for point cloud and triangle mesh manipulation, including surface reconstruction, registration, filtering and reshaping. [C++, Boost, PCL, OpenMesh, Eigen]. STT, Spain. 2013-2021;
• MetaDabaseUI. At STT I’ve developed a reusable module for database of patients and their individual sessions (scans, motion capture), that can be embedded in any Qt or MFC application as an independent component. This module generates the UI and DB structure from a meta-data file. [C++11, Qt5, XML]. STT, Spain. 2013;
