Available to hire
I’m Zakaria Fakhi, a full-stack Java and Angular developer and a tech lead specialized in building modern, high-performance business web applications. Across insurance, telecom, services, finance, and aviation sectors, I’ve worked end-to-end on functional analysis, technical design, front-end/back-end development, REST APIs, testing, continuous integration, and code quality—always with a strong focus on maintainability and delivery.
I also enjoy leading teams and shaping technical decisions: at Allianz France I acted as Tech Lead for a B2B professional insurance subscription journey, coordinating developers, product owners, DevOps, and business stakeholders. With experience using Angular (RxJS, NgRx, Angular Material), Java (Spring Boot/Spring Batch/Security), and strong DevOps practices (Docker, Jenkins, SonarQube, Git), I’m now available for Java/Angular freelance assignments where team support, software quality, and pragmatic engineering matter.
