About Me
My name is Lyes Sefiane, Algerian Citizen Native 馃嚛馃嚳 and Canadian Citizen by Naturalization 馃嚚馃嚘, since 2024-05-07 with 02 Master's degrees from two different Paris universities (Paris 8 University and Paris Dauphine University) and a Bachelor's degree from the University of Tizi-Ouzou in Computer Science field. Software Engineer 3 饟個 with 8+ years experience designing and developing software using the Java ecosystem such as Java 8 +, Spring Framework 5+, JUnit, PostgreSQL, Redis, MongoDB, Docker, Postman, Openapi/Swagger, to develop Desktop, RESTful Webservices, and Microservices applications by applying Agile Scrum methodology. Please refer to my LinkedIn and GitHub profiles for more information.
After 5.4 amazing years developing, designing, expanding a Java Desktop Application (Java 11, JavaFx/OpenJFX and Spring Core Framework) at Ciena as a full time employee dedicated to the Optical Networking domain (reporting to the Director Service Innovation at Ciena) to aid the Ciena's network engineers on their daily tasks, I resigned from Ciena on July 29th, 2022 which triggered a full background check.
During my experience at Ciena I managed the software development team of 04 Software Developers contractors and 02 Internships students using the Agile Scrum methodology for more than 03 years.
Currently looking for a career advancement inside/outside Canada following my move from Montreal to Ottawa on December 1st, 2022 where I earned my Educational Credential Assessment (ECA) provided by the Comparative Education Service (CES) of the University of Toronto of my Master's degree of Paris Dauphine University.
Do not hesitate to reach out to me for more information.
