My brand to provide IT-related services. Established 2008.

Some of the projects I've worked on over the last years:

- 2018-2019: Full frontend development for OTT company using React and other related technologies like DRM and Chromecast.

- 2012-2016: Centralized multi-domain CMS system for video websites. Full automatization of processes
(video publishing/transcoding/previews generation/reviewing/moderation/work elements/CDN control) across different domain names, transcoding of videos for different devices. Single administration panel to manage the entire network of websites independently on their server location.

- 2014: Integral UI development for a STB (Set Top Box) based on Webkit. The customer is an OTT providing IPTV services and I had to fully develop the Interface for the typical main functions of this devices: TV stream, channels organization, EPG (TV Guide), Teletext (I was directly decoding the MPEG/TS stream), Record scheduler, Media player. Efficiency of the code was very important as processing capacity of these devices is pretty limited, and a quick response to user requests is needed.

- 2015-2016: Social Hotspot system. Project including different elements on its architecture:
a) Router firmware based on Debian, developed from scratch.
b) Centralized administration panel (router management plus billing control) where customers can access
to modify the router settings (ESSID, login otions). This administration panel keeps direct communication with different routers via VPN so settings can be propagated immediately by user request.

Stefan Weber - 1xINTERNET


Working with Jorge was great! We had a complex RN project in bad shape that needed updating to RN 0.61. Jorge showed that he has a deep understanding of the matter, also the specifics of the iOS and Android native parts. Jorge was able to solve all issues in a short time. Apart from the technical proficiency, Jorge is a friendly and reliable person. He also is able to work self-responsible and drive a project. We'll definitely book him again!

Stephen Kneubuehl - RoadStr Enthusiast, S.L.


Jorge collaborated on our Node.Js backend project, touching important aspects of client security, data modeling and schema design in relation to our MongoDB database, and definition and implementation of an Elasticsearch stack. These were complex tasks, and Jorge was able to enter the project, understand the requirements, and deliver appropriate solutions. He is a talented developer who is eager to learn and to master new technologies. Jorge was able to deliver under difficult timelines and circumstances. He communicated in a professional manner and worked well with the team.

Alejandro Prats - Arts Internet Solutions


Jorge supo liderar un equipo técnico de diversos ámbitos como Administración, programación e incluso diseño gráfico de una manera muy profesional. Es una persona comprensiva y con una mente brillante, que supo manejar cada situación con soltura. Nos adaptamos a situaciones difíciles en todo el tiempo que estuvo, pero el siempre se mantuvo a la cabeza, y eso da mucho apoyo y moral a sus compañeros. Con respecto a sus conocimientos, no creo que se le pueda caracterizar menos que a un genio, con una mente brillante que sabe visualizar todos los elementos y asociar lo adecuado para cada momento. Aprendí muchísimo de linux a nivel de servidor y tecnología de redes con cisco. Sin duda le recomiendo para cualquier empresa que necesite de sus servicios.

Joan Condal - Infotec Condal S.L.


Jorge ha realizado un extraordinario trabajo interno en mi empresa basado en programación en PHP, AJAX y python, el cual uso como base para muchos de mis proyectos. Tambien es un excelente administrador de servidores Web basados en Linux y un amigable y honesto socio mientras duró nuestro proyecto compartido de servicios de hosting: Condalis. Lo recomiendo encarecidamente para temas de programación avanzada, asi como de gestión de recursos técnicos y planificación para proyectos de mayor envergadura.
