Malagadev

CEO

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

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


- 2019: Optimize node.js backend by refactoring the entire application flow, including designing, deveoping and deploying the entire new security strategy of the service. This backend is being actually used by a mobile application having more than 125.000 registered users by June 2019.

- 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.

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.
