I define myself as a responsible, tenacious, and patient person, being committed to the projects I am assigned to. I am a “Never Stop Learning” passionate, ready for the next challenge.

Electrónica Martínez

Software & Network Systems Engineer

Noteworthy results:

- Wrote a script in Python to connect via HTTP to all the routers of the company, in order to change several parameters using Selenium
- Cleaned a lot of disorganized data of the old ERP to incorporate it into Odoo, the new ERP of the company, using parallelization in R
- Developed a running task to gather info from 200+ HotSpot APs, and display them beautifully, being “impossible to do” as the CTO and the CTO's right arm said.
- I created a Web Interface for a VDSL DSLAM Huawei via SSH in R.
- Created a Telegram Bot to open the different doors the company has.
