About Me
Lyes SEFIANE, born on August 30th, 1988 in Tizi-Ouzou, Algeria, is an Algerian-Canadian dual citizen, Native Amazigh (Indigenous peoples of North Africa), Native Kabyle (an Amazigh ethnic group indigenous to the mountainous Kabylia region of Northern Algeria), Software Engineer 3 residing in Ottawa, the Canada's capital city. He received multiple positive recognitions, referred to as "Ciena Bravos", from his colleagues at Ciena Corporation for his Customer First, Innovation, Velocity and Outstanding People.
Graduated from the Université Mouloud Mammeri de Tizi-Ouzou (Algeria) with a Bachelor's degree, Computer Science (Fairly Good - Honors) in 2010 after successfully earning a Baccalaureate Diploma, Natural and Life Sciences (Fairly Good - Honors) from Lalla Fatma N'Soumer Secondary Education School of Tizi-Ouzou in 2007.
On August 2010 I was accepted into the Université Paris 8 Vincenne-Saint-Denis, a French higher foreign educational institution via "Campus France Algérie" to pursuit my studies where I earned a Postgraduate Diploma, Computer Science (Fairly Good - Honors) in 2011 and my first Master's degree, Computer Science & Human Sciences (Fairly Good - Honors) in 2012.
After successfully completing my research internships at Laboratoire IBISC in the context of my first Master's degree, I was accepted by the prestigious Université Paris Dauphine-PSL where I earned in 2014 my second Master's degree, Computers and Intelligent Systems (Fairly Good - Honors) jointly awarded with Grande École AgroParisTech (part of the Université Paris-Saclay) a member of ParisTech (Paris Institute of Technology, a cluster of Grandes Ecoles of most prestigious French leading engineering and business schools), following the completion of an engineering & research internship at EDF R&D.
After more than a year as President of IT-DMSIC Corporation (Dismissed permanently on 2016-06-22), I immigrated to Canada as skilled worker (Certificat de Sélection du Québec (CSQ) issued on 2015-11-17) where I signed the confirmation of my Permanent Residency in Montréal-Pierre Elliott Trudeau International Airport on October 2016.
As Algerian, Native Amazigh, Native Kabyle and Permanent Resident of Canada, I worked in the Services R&D organization at Ciena Corporation (a U.S. optical networking and software company based in Hanover, Maryland) for 05 years and 3 months (As full time employee and contractor), Department C1100, to engineering official Ciena Corporation's desktop software products named NAVA and NAVA Collector Agent available for the Windows platforms as Software Engineer 3 and Product Owner, written with Java 11, JavaFx/OpenJFX and Spring Core dedicated to the Optical Telecommunication domain to aid the Ciena Corporation's telecommunications engineers on their daily tasks. The NAVA project came to an end on December 2021, successfully completed and fully delivered (including digital signature).

"Hi Lyes SEFIANE - just a note to express appreciation for the extra mile you went to help out with the Rogers network collection as the project quickly approaches a deadline. This bravo could also be for innovation due to you realizing the building blocks of the solution lay within NAVA, however the speed in which you turned around the result and re-worked parts of the tool was the most impressive. Enjoy your vacation, I think you ve earned it!"

Core Value : Customer First
Issued by Drew RAWLINGS
Senior Network Engineer at Ciena Corporation
Ottawa, ON, Canada
August 15th, 2019
"Having worked with Lyes SEFIANE for over a year developing a custom Java application (NAVA), I can honestly say it was a true pleasure working with him. He is a very dedicated, hard-working person, who was more than willing to put in extra effort whenever a deadline was approaching. Lyes SEFIANE has an incredible aptitude for learning new technology, even when it was completely unrelated to anything he had worked on in the past. He would not hesitate to ask for clarification or additional details on a topic, and was also very proactive in getting clarification when feature requirements were vague or misleading. When responses were delayed, he would move on to another task, or make an assumption on how to proceed and move forward with completing the feature work. His ability to apply his knowledge of our telecom product to testing his features was also extremely impressive. He definitely went above and beyond when performing designer testing."

"Lyes SEFIANE I want to take a moment to recognize your effort in the development of the DCN Viz feature in NAVA. This tool was requested by BT when they manifested their interest in purchasing NAVA. You showed a lot of initiative by ramping up on your own and finding innovative solutions to deliver the feature with great success. The feedback we got from BT was very positive and they were extremely impressed with the DCN functionalities. Thanks again for your efforts and overall commitment to NAVA."

"The provided document is an Algerian Military Card, Qualified, but not drafted (مؤهل لا يجند) for the individual named Lyes SEFIANE (Decision Date: August 21st, 2002, relates to the original decision, card issued January 30th, 2014).
This is an official document issued by the Directorate of National Service under the Algerian Ministry of National Defense. It is issued to Algerian citizens who are exempted from mandatory military service due to specific circumstances.
Important Recommendations
- The card is personal and must be presented upon any request or inspection.
- In case of loss or theft, the National Gendarmerie unit at the place of residence must be notified.
Exemption Context
Exemptions from Algerian national service can be granted for various reasons, including medical conditions, being the sole family support, or being above a certain age while employed. The status "Qualified, Not drafted" indicates a specific regularization of status rather than a medical exemption (which is another category)."
