Top SchoolHamza Topçuoğlu is a Principal Software Developer based in Istanbul with eight years of hands-on experience building Java-based backend systems, microservices and telecom billing platforms. He has progressed from early web and .NET projects to senior roles at Huawei, Crossover and Turkcell, earning a Huawei R&D Best Individual Contribution award in 2014 for impactful delivery. His expertise spans Spring Boot, Kafka, Docker, CI/CD pipelines and multiple databases, and he frequently combines backend services with front-end integrations (AngularJS/React-style templating) for end-to-end solutions. At Turkcell he worked on high-availability billing and a video conferencing platform (BipMeet), and at Crossover he architected cloud and charging dispatch systems for global customers. Colleagues describe him as a pragmatic architect who pairs deep telecom domain knowledge (BSS/OSS, provisioning, mediation) with a developer-first approach to observability and testing. He brings a track record of on-site customer work, migrations and orchestration projects that make him well-suited for complex distributed systems and legacy-to-cloud transformations.
