aka. streamerd · full stack engineer
Full stack engineer and hands-on CTO. 10+ years shipping cloud-native platforms across banking, insurance, telecom, and energy, including four years in Germany. Recently building cybersecurity products in Go: identity, post-quantum file security, and AI agent enforcement.
Interposed
A governance and enforcement layer for AI coding agents. A per-host Linux daemon and a fleet operator put every action an agent takes — exec, file, network — under policy: the agent uses a cooperative intent plane to pre-clear its work, trusted actions pass, and anything gray-area waits for a human. Built in Go, validated end to end on a live fleet.
declare_intent / query_policy / request_approval) so the agent plans around policy instead of trial-and-error — the human approves fewer, clearer things.ConsAuth Systems
Consent-first identity platform: custom IdP + OAuth2/OIDC (Ory Hydra), Go services, PostgreSQL/Redis. SSO across apps with user-owned preferences and Solid/WebID-aligned flows; optional private pod provisioning.
Governate Oy
Post-quantum file security platform built from scratch in Go on GCP: hybrid AES-256-GCM + Kyber-1024 encryption, policy-based access control, and cross-platform clients.
