Systems I have designed, built, and defended—from deterministic AI evaluation harnesses to guarded production writes.
A deterministic harness for fault injection, independent evaluation, trace reconstruction, replay, and statistically defensible reliability claims. Provider integrations plug into explicit seams without weakening the reproducibility boundary.
A preregistration-grade research program testing whether recovery engineering can substitute for model capability while preserving task correctness and transactional safety—and where that substitution breaks as workflow dependency depth increases.
A production pipeline that extracts data from unstructured invoices, matches it against ERP records, and places a deterministic validation gate in front of every write to a live financial system.
Published research and implementation for converting noisy engineering BOMs into ERP-safe manufacturing BOMs using BLOCK / REVIEW / PASS conflict classification and an absolute safety gate before Odoo execution.
End-to-end technical ownership of a large education platform: monitoring, incident response, database and infrastructure performance, and production reliability.
Security-focused open-source work covering gateway exposure, authentication bypass edge cases, token-expiry awareness, and non-breaking secure rotation across request paths.
