Cristian Mihai
Software Developer at Infosys
Bucharest, Romania
Summary
🤩
RockstarCristian Mihai is a software developer based in Bucharest with 8 years of experience building backend systems in Java across enterprise environments like Infosys, Luxoft, and IBM. He works with Spring Boot, Hibernate, SQL databases and Kubernetes, delivering production-grade services and platform integrations. Beyond enterprise Java, he contributes low-level system code to the high-profile unikraft project, adding ISR-safe routines, ACPI support and precise delay primitives—showing rare fluency in both application-level services and kernel/boot-level programming. That mix of cloud-native backend expertise and systems-level contributions suggests strong debugging skills, attention to concurrency and performance, and an ability to operate across the full stack of software infrastructure. Colleagues can expect a pragmatic engineer comfortable in large teams who also dives into foundational code when performance or correctness demands it.
