Cybersecurity, backend development, and AI automation

I build tools for security investigations, reliable APIs, and workflows that keep consequential decisions under human control. My projects focus on repeatable results, failure handling, and documentation that makes the work easy to inspect.

I'm interested in opportunities across cybersecurity/SOC, backend software development, and AI automation.

Selected projects

Project Problem it addresses Engineering evidence
SOC Incident Investigation Lab Investigate a simulated Windows account compromise Python correlation engine, EVTX ingestion, Sigma rules, incident reports, and automated tests
Packet Proof Find inconsistencies across trade documents before release Document extraction, deterministic validation, audit hashes, fixture replay, and human review
Decision Gate Handle repeated inbox events and escalate consequential requests SQLite persistence, idempotent ingestion, Strands tools, a reviewable outbox, and a separate approval CLI
API Reliability Kit Handle common API integration failures Pagination, bounded retries, duplicate suppression, conflict detection, and resumable state
DopamineDesk MCP Adapter Connect agents to a pay-per-call data marketplace OpenAPI-driven tool discovery, free previews, opt-in payment handling, and per-call limits
Revenue Sentinel Turn uncertain opportunity listings into an auditable review queue Deterministic scoring, FastAPI, Google ADK integration, evidence digests, and ledger storage

Explore the work

The SOC lab uses synthetic telemetry. Packet Proof includes a fictional-document demo. Decision Gate's current implementation stages responses in an outbox; it does not send messages. Each repository documents its scope and setup.

Tools I use

Python · JavaScript/Node.js · FastAPI · SQLite · Git/GitHub Actions · OpenAPI · Sigma · Windows event logs · MCP · Google ADK · Strands Agents
