Within this collaborative environment, my work focuses on enhancing Tracee's capabilities to monitor systems and applications in real-time, analyzing events to identify suspicious behavior. My contributions are within a team setting, working on both kernel space components in eBPF (C) and userland programs in Golang, to improve Tracee's detection efficacy and security measures.https://github.com/aquasecurity/traceeBeyond my team-based engineering efforts, I am involved in the collaborative development of libbpfgo, a Go library created to facilitate interactions with Linux's eBPF from Go. This library supports the operational needs of Tracee, embodying our collective commitment to advancing runtime security and open-source tooling.https://github.com/aquasecurity/libbpfgoAdditionally, I contribute to BTFhub, an initiative that, in collaboration with the BTFhub Archive repository, provides BTF files for all published kernels lacking native embedded BTF support. This critical work facilitates the use of eBPF programs across various kernel versions, enhancing compatibility and enabling broader adoption of advanced security measures.https://github.com/aquasecurity/btfhub Show less
