Projects

Prod work stays behind the firewall. These are the public versions.

Transformer-Based Anomaly Detection — TensorFlow/Keras transformer autoencoder over multi-metric telemetry. Trained on healthy traffic; reconstruction error is the score. Test: precision 0.95, recall 0.83, ROC AUC 0.97. Returns per-metric attribution so a detection says which metric broke, not just that something did.

Incident RCA Pipeline — Correlates Prometheus/ELK alerts into severity-ranked clusters, tags them as origin / correlated / separate, drafts runbook steps from the alert text. Optional LLM summary (Ollama or any OpenAI-compatible endpoint) with prompt redaction and a deterministic fallback if the LLM fails.

ansible-roboshop — 11-service stack end to end with Ansible (EC2, Route 53, MongoDB, Redis, MySQL, RabbitMQ, app tiers, systemd, NGINX).

shell-roboshop — Same stack in Bash — what a deploy looks like before you pull in Ansible.

terraform — Remote state, loops, conditionals, data sources, multi-env layouts.

Portfolio — Static site, no framework / build step. Strict CSP, security headers.

Currently

Running Gemma offline in a home lab with a log stream, as a local incident-response assistant that drafts RCA steps without data leaving the box.
