Back to original languageAbout Khalil
Senior developer passionate about modern architectures and the transformation of complex systems.
I have worked on large-scale projects in critical contexts (public and banking sectors), where I contributed to evolving monolithic systems towards microservices and micro-frontend architectures.
My role is not limited to development: I also intervene in technical design, architectural choices, software quality, and team coaching.
I enjoy working on fundamental topics: performance, robustness, IT system integration, and delivery industrialization.
