Hello! I’m Wael Antar, a junior full stack engineer blending solid backend with Java and Spring Boot and frontend with Angular. I specialize in building robust RESTful microservices, working with SQL/NoSQL databases, and deploying containerized applications on AWS. I’m currently at Voxloud in Rome, where I help enhance UI/UX and integrate AI voice agents to improve user experience.
I’m passionate about translating business needs into scalable architectures, writing clean, testable code, and collaborating across product and design teams. I’m open to relocation or remote opportunities and excited to continue growing in backend, cloud, and full-stack development.
