My background story

Lisbon Portugal

Hi, my name is Antonio Feijao, born in Portugal and currently living in London, UK.

In highschool I followed the technologies path where I learned the fundamentals of Computer Science and Programing.

Then, I the pursued a 5 years University degree in Electronics and Telecommunications Engineering.

I did learn a lot but was very difficult for me after second here. I had minor background in Electronics.

Never give up!

So, to improve my electronics skills, while studying at the University, I also enrolled in a 3 years part-time night course in "Telecommunications and Networking Specialization".

The private school was called "Forino", but since then has renamed to CINEL.

It was here that I found my passion for Networking. I was a student at Cisco Network Academy for 1.5 years Cisco NetAcad.

After passion my CCNA Routing and Switching Cisco Exam, I got a job offer at Unisys as a Security Consultant and Penetration tester.

I was trained in many areas os security!

Here, I found another passion, Security! I learn best practices, tweaking and hardening configurations configurations, Windows, Linux and Networking.

I learned so much I! I actually like to learn new things every day.

As a Security Consultant, I worked with the largest organizations in Portugal in Finance, Banking.

Luanda Angola

After 1 year experience as a Security Consultant, I was assigned to a 3 years project in Africa, Angola, City of Luanda - Minister of Defence.

Hand-on work, assembling racks and data centre equipment, and yes it had servers, cables, networking devices. This took about 1 months.

My responsibility included:

Year 1

  • Networking configurations following the best security practices
  • Monitoring and Alerting Applications
  • Connecting the various cities in Angola back to the Data-Centre in Luanda. (Some cities were connected through satellite trucks, it was great experience tweaking packets sizes, window-size and MTUs for latency improvements)
  • Networking for standalone trucks connected through satellite
  • Collaborating with other teams, mostly Develops, Microsoft Administrators and the Project Managers

Year 2

  • Training the various local teams that would look after the Network Infrastructure
  • Continuous improvements
  • Collaborating with other teams

Year 3

  • Continuous improvements
  • Firmware upgrades
  • Training the local Engineers

I meet amazing people during my stay in Angola.

London United Kingdom

After this project, I went back to Portugal. I had learned so much in the past 5 years, but I wanted more.

Most of the technical documentation was in English. In some occasions, I had to engage with the Cisco support. I had the feeling that sometimes I was struggling with the English language.


Fast forwarding, that is why I moved to England.

Good explanation on the site above, with except on the following sentence: "Some AWS Solutions Architects are focused more on products and not on the customers."

At Amazon and AWS, the company culture starts with Customer Obsession!
