Local-first tools, security evidence and infrastructure systems that stay reviewable.

I am a FOSS maintainer, security researcher and infrastructure-focused engineer. My work sits around the parts of software that need to stay understandable under pressure: HTTP and TLS behaviour, reverse proxy edge cases, release evidence, infrastructure review, vulnerability validation and project history.

I build local-first tools that produce durable artefacts rather than opaque output. The goal is usually the same: make decisions easier to inspect, reproduce and carry forward after the original platform, issue tracker, cloud account or release page is no longer the source of truth.
