I provide application security, network engineering, and DevSecOps services with a strong focus on practical vulnerability discovery, fuzzing, secure infrastructure, and automation. I hold a Master’s degree, which strengthens my analytical approach to complex engineering, cybersecurity, and infrastructure tasks.
My core expertise includes fuzz testing with AFL++, libFuzzer, sanitizers, coverage-guided testing, corpus and dictionary preparation, crash triage, harness development, and security regression testing. I can help analyze complex C/C++, Linux, networking, and backend projects, identify high-risk attack surfaces, build fuzzing pipelines, and integrate security checks into CI/CD.
I also work with Linux systems, Docker, QEMU, VPN infrastructure, OpenWRT, routing, firewall rules, network diagnostics, and secure deployment workflows. For DevSecOps tasks, I can prepare reproducible environments, automate testing, harden services, review configurations, and document security processes clearly.
Typical services I offer:
- Fuzzing setup with AFL++, libFuzzer, ASAN, UBSAN, and coverage reports
- Fuzz harness development for parsers, protocols, daemons, and libraries
- Crash reproduction, minimization, triage, and root-cause analysis
- Linux/network security testing and configuration review
- DevSecOps automation, CI/CD security jobs, Docker-based test environments
- VPN, routing, firewall, and infrastructure troubleshooting
- Technical security documentation and reports
I focus on engineering-quality results: reproducible steps, clear reports, actionable findings, and practical fixes. My goal is not only to find bugs, but also to help you build a repeatable security testing process that can be used by developers, QA, and security teams.
