SOC Detection Lab

Security · AWS · 2026

Live dashboard ↗ GitHub ↗

Edge-to-cloud SSH honeypot. A Cowrie sensor on a Raspberry Pi 5 captured real attacks over a 14-day run, and its logs flowed through a serverless AWS pipeline into a live React dashboard.

  • 36,440 attack sessions from 1,322 IPs in 83 countries, correlated and GeoIP-enriched.
  • Deployed 8 Sigma detection rules in Kibana, mapped to MITRE ATT&CK credential access, persistence and command-and-control.
  • Pipeline built in Terraform: S3 → Python Lambdas → DynamoDB → API Gateway → CloudFront.
  • Every merge gated on 262 tests, secret scanning and Sigma validation, deployed by GitHub Actions over OIDC.

As deployed for the May 6–21, 2026 run: a Raspberry Pi 5 running Cowrie as a k3s pod, reached through HAProxy on a DigitalOcean droplet over an autossh reverse tunnel (both edge hosts since decommissioned). fluent-bit ships logs to S3, then Lambda ingest (timestamp-window correlation and MaxMind GeoLite2) → DynamoDB → aggregator → API Gateway HTTP API → React dashboard on CloudFront behind Cloudflare.

Tokyo Zero

Founder · since 2022 · $100K+ revenue

Case study ↗ Storefronts ↗ Design process ↗

My anime-inspired streetwear and merchandise brand, and my career before IT. I founded it in 2022 and ran it end to end, growing it past $100K in revenue with a repeat customer base, selling at conventions and online.

  • Designed the brand from the ground up: art direction and product design for 30+ products (prints, die-cut stickers, deskmats, tapestries, flags, totes and lanyards), the visual identity and three themed storefronts.
  • Directed a small remote team and independent artists through brief, review and quality control on every release; shot the product photography and ran social media, drawing 100K+ engagements.
  • Rebuilt the brand’s portfolio as a case study on a multi-region AWS stack in Terraform, with CloudFront failover to an S3 replica in a second region.
  • Hourly canary and a nightly digest Lambda behind live /status and /insights pages; the contact form runs on API Gateway, Lambda and SES, deployed by GitHub Actions over OIDC.

Cloudflare DNS → CloudFront (OAC, security headers, URL-rewrite function) → S3 in us-west-2, replicated to a DR bucket in us-east-1; the origin group fails over to DR on 5xx or timeout with no DNS change. The contact form posts to API Gateway → Node 20 Lambda → DynamoDB audit and SES. An hourly Synthetics canary watches three pages, and a nightly EventBridge job runs the digest Lambda (Athena over CloudFront logs) that publishes /status and /insights.

Homelab

Networking · Systems

Three-node Proxmox cluster on a VLAN-segmented Cisco network, built to practice enterprise networking, identity and security operations hands-on.

  • Cisco Catalyst C1000-8T: VLANs, trunking, inter-VLAN routing and ACLs; Ubiquiti UniFi for managed wireless.
  • Windows Server Active Directory with Group Policy, DNS and DHCP, hybrid-joined to Entra ID with Intune.
  • Proxmox VE HA with ZFS replication, live migration and out-of-band management over HPE iLO and Intel vPro/AMT.
  • Ansible patching, scheduled backups and UPS-backed shutdown via NUT.

Homelab · network topology

Internet → ISP gateway → Cisco Catalyst C1000-8T (VLAN segmentation: management and servers) → UniFi U6+ wireless and a three-node Proxmox HA cluster (2× Dell OptiPlex Micro and an HPE MicroServer Gen10 Plus v2) with ZFS replication, live migration and out-of-band management over HPE iLO and Intel vPro/AMT. An APC UPS with NUT handles graceful shutdown for the whole rack.
