Electrónica Martínez

Software & Network Systems Engineer



Developer, systems integrator, system admin and network assistant

Noteworthy results:

- Creating, managing and deploying the needed software in order to auto-configure routers and synchronize DBs. For every new client, now we lose only 3 minutes, rather than 30mins that was the time we were spending before. Total: 10x in saved time.
- 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.
