Hi, I’m Ali Bouali - {Alibou}
Since embarking on my software development journey in 2011, I have had the privilege of working on a wide array of projects for various companies. This diverse experience has enabled me to acquire proficiency in numerous technologies, including Java, Spring, Spring Boot, Hibernate, AWS, and more. The expertise I have cultivated over the years has been instrumental in propelling me to the level of a senior software engineer.
As a developer, my unrelenting drive to excel stems from my fascination with the seamless interoperability of diverse programming languages within a single ecosystem, despite their fundamental differences. In essence, it is the synergy of the technical stack that truly captivates me. The ever-evolving landscape of software development fuels my passion for learning new technologies and continually expanding my skillset.
Having accrued years of valuable knowledge and experience, I felt compelled to share my insights with others. Thus, I established a YouTube channel and a personal website, through which I publish informative videos and courses aimed at empowering fellow developers to enhance their expertise and proficiency in software development.
