About me:

BSc. Electronics Engineer (6 yr. degree) from National Technological University - Argentina (2005).
Previously I got a technical highschool degree in Electrical Sciences at Pablo Nogués Technical High School - Argentina (1996).
I am a quick learner and I can easily adjust to any environment. I am a team player, and I enjoy working with a variety of 
people from different backgrounds. I'm constantly updating myself to the latest technologies.

  Featured Projects

Capillary Viscometer with  LabVIEW
Arrangement of emitter and receivers of red light with photosensitivity in the wavelength of 870 nm. 
The measurement of viscosity is done by making a curve in LabVIEW with the values obtained from the board.
The fluid under test (in this case an oil derived) is characterized by its rheology. When the fluid runs across the 
capillary tube and it intercept the beam of light, it changes the light angle and this variation is received by the 
phototransistor through a PMMA optical fiber. The progress of the fluid is displayed both by hardware with blue LEDs 
and in the VI.

Complete GPON Network and development of an ONT
Realization of a complete GPON (Gigabit-capable Passive Optical Network) network from the scratch with 
an OLT Zhone MXK 319 and ONTs Zhone ZNID-2516 and ZNID-2517.
connected between them through a PLC splitter (Planar Lightwave Circuits Splitter) including: physical set-up, 
dedicated earthing system and workbench. Configuration of the UPLINK and DOWNLINK boards. ONT configuration.
Realization of an optical attenuator with a coil of optical fiber in order to simulate more distance between OLT 
and ONT (suscriber side). 
ONT development - Programming of a commercial ONT development kit: Creation and compilation of boot 
system with U-boot. Creation of filesystem in JFFS. Compilation of the Embedded LINUX Kernel and intallation in 
the SoC. Compilation and installation of all software, LAN, OMCI stack and other software to make the ONT operable.
Programming and burning in the ONT kit was carried out through EJTAG, UART and LAN, whilst in the OLT the task was 
performed with RS-232 and Telnet/PuTTy. The file transfer to the ONT was realized through TFTP.
