Summary

Hands-on technologist focused on security, with a strong interest in OSINT and wireless. Builds and tests real hardware: Wi-Fi auditing rigs, ESP32 firmware, sub-GHz radio tools and Home Assistant automations, all on equipment I own. Uses AI coding tools to build AI assistants, flight trackers and security tools. Brings years of fast-paced, customer-facing hospitality experience and the patience, planning and composure of full-time parenting. Seeking help desk / IT support, SOC analyst or IoT security roles.

Security & Embedded Projects

Wi-Fi Wardriving & Packet Capture Rig (Pwnagotchi)
  • Built a portable Raspberry Pi Zero W unit with an e-ink display, a USB Wi-Fi adapter in monitor mode and GPS.
  • Wardrove to collect geotagged 802.11 captures (.pcap) and analyzed traffic and handshakes in Wireshark; all testing on my own networks.
DIY Flipper Zero Alternative (ESP32 + CC1101)
  • Assembled an ESP32 multi-tool running Bruce and Marauder firmware to study Wi-Fi, Bluetooth LE and sub-GHz radio.
  • Used the CC1101 radio to capture and replay signals from my own devices, turning it into a universal remote, then tied those devices into Home Assistant automations.
AI Voice Assistant & Home Automation
  • Built a Home Assistant voice satellite on a Seeed XIAO ESP32-S3 with ESPHome and on-device wake-word detection.
  • Used AI coding tools to build AI assistants, and created many Home Assistant automations using its REST API.
  • Designed an ESP32 touchscreen control panel (ESPHome, ILI9xxx display, XPT2046 touch) for a smart speaker, iterating through 10 revisions.
Surveillance Detection & OSINT Tools
  • Deployed and evaluated open-source BLE/Wi-Fi surveillance-detection firmware (OUI-Spy, Flock-You) on the ESP32-S3.
  • Wrote a Shodan API module for an ESP32 display with a caching state machine that conserves query credits.
ESP32 Display Firmware
  • Real-time ADS-B flight radar on a round GC9A01 display, fed by the OpenSky Network API (XIAO ESP32-S3).
  • ESP32-C3 Wi-Fi dashboard rotating weather, markets, sports and news cards pulled from public REST APIs and RSS.
C/C++, PlatformIO, Arduino, LovyanGFX, SPI displays, LittleFS
Home Lab & Self-Hosting
  • Set up a WireGuard VPN, an Unbound recursive DNS resolver, NextCloud, Docker and a LAMP stack; designed a small home/office network. Documented each build at stevenagri.com.
