I love Plants, Tech and AI

• 🚀 Core Stack: TypeScript, React, Angular, Node.js, C/C++, and KiCad for hardware design.
• 🛠️ Current Focus: Custom embedded firmware optimizations, e-ink interfaces, and automated cultivation monitors.
• 🌱 Domain Expertise: A strong background in IT infrastructure paired with deep experience in Integrated Pest Management (IPM) and greenhouse automation.

📂 Featured Projects

📡🔒 Ruby Firmware

Custom firmware for the XTEink X3 and X4 e-ink readers that turns the hardware into a stealthy, long-battery-life passive RF signal analyzer — with a small digital companion living in the corner of the screen.

• Passive RF Capture: 802.11 monitor-mode WiFi sniffing (beacons, probe requests, WPA 4-way-handshake detection) plus passive BLE advertisement scanning — receive-only by default, nothing associates, pairs, or transmits.
• Encrypted On-Device Logging: Every observation is deduplicated and independently written to an AES-256-GCM encrypted daily log, decryptable right on the device with no PC required.
• Ruby, the Companion: A small creature reacts with a changing mood as a live front-end for what it's hearing, plus a Level 1-5 badge and header EXP bar tracking lifetime progress from unique devices seen and handshakes captured.
• Opt-in Auditing Tools: Raw .pcap handshake export for offline password auditing with hashcat, plus an active-deauth capability gated behind an explicit, off-by-default whitelist/blacklist targeting system.

🌿🐣 CrossPlant Firmware

An open-source custom firmware fork for the XTEink X3 and X4 mini e-ink readers. It merges the advanced typography and performance optimizations of *CrossInk* with a re-engineered virtual plant companion mechanics system (*CrossPet*).

• The Virtual Plant System: Features a reading-driven ecosystem where plant stats (Moisture, Happiness, Health, Discipline) decay in real time while awake, evolving through branches (Scholar 🎓, Balanced ⚖️, or Wild 🌲) based on actual reading habits and streaks.
• Premium Features:

* A space-efficient Two-Column UI separating plant vitals from detailed reading partner statistics. * Dew Drops (DD) Economy: Real-time reading reward synchronization (+1 DD per page, +100 DD per book, time-based accumulation) to spend in an interactive item & cosmetic accessory shop. * Dynamic Canvas Rendering: Pixel-art accessories (Glasses, Wizard Hats, Crowns) scale and render directly on top of the plant's sprite. * Plant Diary Sleep Screen: A dual-pane standby screen displaying your sleeping plant alongside an RTC-synced daily achievement summary. * Hardware Optimizations: High-fidelity SD card .bmp asset probing, custom bezel key long-press shortcuts, and a research-backed typography engine featuring *Lexend Deca* and *Bitter*.

🎣 Bio Tackle Box

A dedicated, full-stack application designed for agricultural management. It streamlines digital tracking, workflows, and essential data management for specialized growing environments.

• Stack: TypeScript, React, and Angular framework infrastructure.

💧 HydroLogix - DWC Monitor (Custom Hardware)

An automated Deep Water Culture (DWC) environmental monitor built from the ground up to track real-time reservoir metrics.

• Hardware & Firmware: Custom schematic capture and PCB layout routed entirely in KiCad.
• Features: Utilizes an Elegoo HC-SR04 ultrasonic sensor for precise, real-time liquid-level tracking and environmental telemetry, all housed in a custom-designed, 3D-printed enclosure.
