On this page you will find some (not all) of the projects that I was involved in. I will try to put the most interesting/useful ones here as detailed as I can, if you want to know more details about any of them, contact me.
There is also a list of other projects with simple descriptions for each of them. I haven’t made some of them public due to lack of time, but in case you are interested, contact me and I will publish them/send you details

Masters at IST on communication networks engineering – Dissertation on Instant Messaging Systems
This work consists on planning, developing and deploying an IM system solution for IST’s community, adapted to its current service infrastructure. IM addresses and accounts are associated with the central Identity Provider (IdP) service. This association enables the fast deployment of the optional IM service and its widespread use. The IM system is supported by the current Session Initiation Protocol (SIP) infrastructures using the SIP Instant Messaging and Presence Leveraging Extensions (SIMPLE) standards. This IM service is based on the development of a Java generic purpose open source Message Session Relay Protocol (MSRP) peer library, and its integration with a popular Java multiprotocol IM open source client, Sip-Communicator. This work results in a contribution to the open source and IM worlds by means of software development, and deployment of an IM beta-stage system.

Holography
-
Holostudio
The project consists in generating holographic images based on 2d digital images. The holograms are be projected on a wall using a LASER. Although with some limitations,e.g. no 3d support, the program was successful attaining its purposes of making a simple way to generate 2d holograms.
Instant Messaging Systems
-
SIPp – SIP MESSAGE performance scenarios
These scenarios were created to test the performance of the work done in the ambit of my thesis. They basicly test the mass send of a SIP MESSAGE to try to assert the scalability of an implemented SIP/SIMPLE IM system
-
File transfer over SIP on Jitsi
Implementation of file transfer over SIP/SIMPLE according to RFC 5547
-
Message Session Relay Protocol -MSRP- peer Java library
Implementation of a peer library in Java of the Message Session Relay Protocol (RFC 4975 & RFC 4976)
