About Me
More than 25 years passionately enjoying the world of Open Source. My professional career has been developed around four areas.
- Big Data (Apache Software Foundation Big Data ecosystem)
- Distributed Systems (Apache Mesos, Kubernetes, Openshift, Mesosphere DC/OS)
- High Performance Computing (Sun Grid Engine, HTCondor, IceGrid, Slurm)
- Embedded Systems (Yocto Project, OpenWrt, Embedded Linux Development Kit - ELDK)
Open Source Contributions
Community resource for big data and data science related software projects on techniques and best practices for integrating with Kubernetes.
This group is different from Kubernetes Big Data User Group because, unlike Kubernetes User Groups where though their central goal is not a deliverable piece of work, one of the objectives of this project is to create user-ready deliverables and software tools.
AntelopeDB is a new Hybrid Transaction/Analytical Processing (HTAP) Database Platform. This is a personal on goning open source project (ASLv2.0) actively maintained (contributions are welcome). Architecture overview here.
Apache NiFi active contributor. Actually the contributions to this kind of huge projects is an ongoing process. My first code contribution was offically added in the Apache NiFi 1.12.0 release, in the New Feature section. Here a screenshot of the release changelog (marked the particular contribution).
PPMC (Podling Project Management Committee) for the Apache Myriad Incubator project.
This project (right now retired) was a highly specializated project in the context of Apache Mesos. According with the official description: “Apache Myriad enables the co-existence of Apache Hadoop and Apache Mesos on the same physical infrastructure. By running Hadoop YARN as a Mesos framework, YARN applications and Mesos frameworks can run side-by-side, dynamically sharing cluster resources.”. Some contributions here.
Apache Mesos Fedora
https://src.fedoraproject.org/rpms/mesos
I was the maintainer of the official Apache Mesos package for Fedora. Currently not maintained, due to lack of community and maintenance of the Apache Mesos project.Some contributions here.
The Ben NanoNote (officially the NanoNote) was a pocket computer using the Linux-based OpenWrt operating system. An open-source hardware device developed by Qi Hardware, it was called the world’s smallest Linux laptop. This device was created by the team leaders of OpenMoko initiavite. My personal contrubution was the maintainer of Linux Kernel for the device, in particular the integration of in kernel tree WiFi driver. Some contributions here.
Openmoko was a project to create a family of open source mobile phones, including the hardware specification, the operating system (Openmoko Linux), and actual smartphone development implementation like the Neo 1973 and Neo FreeRunner. The whole project was sponsored by Openmoko Inc. I was a core developer with contributions around drivers related with the mobile vibrator and the backlight (screen inteisity) PWM driver. Some contributions here.
Esware Linux was a linux distribution entirely created in Spain. To date it has been the only linux distribution that was sold in El Corte Inglés mall. The distribution used as base a distribution based on RPM packages, later it started using DEB packages. Esware Linux was very popular in the Spanish Linux world. I was a founding partner of the company, and I was in charge of the technical direction of the company (as well as the main developer).
