What I'm looking for

I'm looking for remote opportunities where I can investigate malware, reverse-engineer Windows binaries, develop detection-focused research, and grow through hands-on work with threat intelligence and security engineering teams.

I conduct independent Windows malware research, reverse-engineering malicious binaries through static and dynamic analysis with IDA Pro, Ghidra, and x64dbg.

I've analyzed 50+ malicious components, including a multi-stage Qakbot sample, tracing loader and payload relationships, Windows API activity, decryption routines, persistence behavior, mutex usage, and anti-analysis techniques.

I translate reverse-engineering findings into IoCs, YARA signatures, and MITRE ATT&CK mappings, while publishing technical research on Medium and Substack and building Python tooling for binary triage.
