Hi, I’m Alex.
Security engineer with a background in embedded systems and firmware. I work at the boundary where software meets hardware, finding what breaks, why it breaks, and what an attacker could do with it.
At my previous company I test the security of network-exposed firmware: attack surface analysis, authentication infrastructure, protocol fault injection, and input validation on real devices. My thesis compares Rust and C++ in industrial bare-metal systems on STM32, covering memory safety, error handling, and incremental adoption without rewriting existing firmware.
What I work on
- Attack surface analysis and protocol fault testing on firmware
- Authentication and access control: RADIUS, LDAP/AD, FIPS, SNMP
- Embedded development in C, C++, and Rust (bare-metal, UART, RS-485)
- Network analysis with Wireshark, Nmap, and Wazuh
Direction
Finishing my BSc in Systems Engineering and moving into ICS/OT or firmware security. Long-term I want to work in security architecture and eventually consult independently for industrial clients. I write about what I build, what breaks, and what I learn from it.
