IT/OT environments · industrial networks · detection & monitoring
I work at the seam between IT and OT. I come from chemical-plant operations — Siemens PCS7, ICS/DCS — and years of watching alarms taught me that the boring log is usually the one that matters. Now I spend my time on the other side of that: securing industrial networks, detection engineering, and incident response.
Currently finishing an M.Sc. in Cybersecurity & Privacy, with an emphasis on network security, cryptography, and industrial cybersecurity.
Ask me about: chemical plant operations · Siemens PCS7 · ICS/DCS · IT/OT interactions.
Off-hours: Dostoevsky, trading-card market data, and a voice assistant I keep overengineering.
- Industry 4.0 IT/OT Lab: Bachelor's thesis lab. Pi Pico sensors publish over MQTT and a Raspberry Pi gateway exposes them over Modbus/TCP to a Node-RED HMI. Includes an architecture diagram and security notes (plain-text MQTT, unauthenticated Modbus, flat network) with IEC 62443-style mitigations.
- jarvis: voice assistant built on Claude Code, with a HUD dashboard and a phone voice bridge over Tailscale.
| Project | What I did | PR | Status |
|---|---|---|---|
| pymodbus-dev/pymodbus OT · Modbus |
Documented the server datamodel example in the published docs. | #3015 |  |
| projectdiscovery/nuclei-templates ICS · Detection |
New network template that fingerprints Siemens SIMATIC S7 PLCs over S7comm. | #17031 | |
| pyca/cryptography Cryptography · PQC |
Fixed missing version markers in the HPKE / post-quantum API docs. | #15567 | |
| openssl/openssl Cryptography · CMS |
Bug fix in CMS signature verification: per-signer results are reset for every SignerInfo when CMS_verify() fails, so no stale state is left behind. Includes regression tests. |
#32643 | |
