Independent Systems Engineer focused on backend architecture, cryptography, and system correctness.

Currently open-sourcing infrastructure tools: • Attest: A tamper-evident audit logging service (Node/Postgres) designed to make database history rewrites mathematically detectable. • SecureVault: A zero-knowledge digital inheritance platform utilizing PBKDF2, AES-GCM, and RSA-OAEP. • Agent Execution Controller: A deterministic runtime with budget guardrails and kill switches for autonomous AI workflows.

I am actively looking for my next full-time Backend / Full-Stack Engineering role at a fast-moving, early-stage startup. If you are building a team that obsesses over failure modes and production-grade architecture, I'd love to chat.
