Rockstar🎓
Top SchoolLeandro Costantino is a versatile software engineer with 26 years of hands-on experience across desktop, mobile, backend and kernel-level projects, from C/C++ and Python daemons to Java Android apps and large-scale EDR systems. He authored the gspca_t613 webcam kernel module included since Linux 2.6.27 and has applied that low-level expertise to security-focused endpoint work at multi-million-node scale. His contributions to major open-source projects like OpenStack (Nova/Horizon) and DuckDB show a mix of bug fixes, API stability improvements and data-processing enhancements. Proactive and self-directed, he experiments with new languages and tooling—recently building a Go memory scanner—while retaining deep strengths in C/C++/Python and a passion for security research.
