Hi, I'm Rey. I build reliable internet, power & automation systems that just work.

Operational Architecture:

• MikroTik /tool netwatch executes recursive ICMP probes against public DNS anchors (1.1.1.1) to monitor RTT average, jitter, and packet loss.
• On degradation, RouterOS triggers a local HTTP payload (/tool fetch) to a Flask daemon running inside Docker on an Orange Pi Zero 3.
• The daemon bypasses cloud servers, opening direct raw sockets on LAN port 6668 via tinytuya to energize backup modems in priority sequence.
• A dedicated monitoring daemon polls the MikroTik ether2-isp2-dito interface, tracking cumulative hardware byte deltas across router reboots and deducting usage from an allocated budget with spoken audio alerts.
• Hotspot user profiles switch dynamically to restrict high-bandwidth consumers while running on cellular standby.

Power Architecture & Protection:

• Paralleled a 24V regulated AC mains supply with a 24V 100Ah LiFePO4 battery pack using high-current Ideal Diode OR-ing modules, delivering sub-millisecond bus transfer without inverter losses.
• Equipped the rail with low-ESR capacitor buffer stages and NTC thermistor jacks to suppress severe inductive inrush spikes from step-down regulators.
• Engineered custom ESP32 firmware ("James Watt") polling cell voltages, current, temperature, and SOC, streaming real-time telemetry to the edge controller's /bms/update endpoint.
• The daemon manages Relay 5 in dual modes: countdown timer or real-time voltage/SOC cutoffs (28.5V or 85% SOC), with scheduled automatic charging windows between 09:00 and 15:00.

Systems Integration & Logic:

• Background thread communicates via DirectSEMS every 300 seconds, capturing PV string voltages (PV1/PV2), battery charge/discharge rates, SOH, and core temperatures.
• Calculates dynamic battery time-to-depletion (down to 21% safety reserve) and time-to-full-charge, rendering 24-hour historical curves via Chart.js.
• Automated Active Inverter Cooling: Monitor polls inverter core temperature; upon hitting ≥ 50°C, it triggers a Tuya smart plug over LAN to energize cooling fans, maintaining a 10-minute hold and shutting down at ≤ 40°C.
• Two-Tier Escalation: Warning alerts dispatch at 55°C (Inverter) and 45°C (BMS). Critical alarms (sirens + Pushover priority dispatch) trigger at 65°C and 52°C.
• Orange Pi CPU thermal bounds are regulated via Hardware Relay 7 driving a dedicated SBC cooling fan.

Safety Integration:

• High-fidelity neural voice synthesis driven by edge-tts using the Philippine English en-PH-RosaNeural model (with automatic gTTS fallback) played directly to a hardware speaker via mpg123.
• Mute schedule matrix attenuates or silences routine solar milestone and utility announcements during night-time sleeping hours.
• Android seismic sensors dispatch HTTP payloads to /api/webhook/earthquake with debounce protection, activating continuous emergency sirens.
• Hybrid Smoke Detection: Checks cloud status instantly; if the WAN is offline, it falls back to a 14-second LAN ping persistence check. Confirmed events initiate a 3-stage sequence: an initial 2-second burst, a spoken room-specific evacuation warning, and a 60-second continuous evacuation siren.

Systems Architecture:

• High-throughput 2.5Gbps switching fabric handles internal routing for high-volume storage, database writes, and Wi-Fi 7 handoffs via Ruijie EW5000 Pro APs.
• Docker container microservices (Immich photo sync, Jellyfin streaming, and the Redtop Boarding House tenant billing ledger) exposed via Cloudflare Zero-Trust Tunnels.
• Integrated Jellyfin Quick Connect authorization bridge allowing family and tenants to pair TV apps using 6-digit codes directly from the local dashboard.
• Bidirectional Python sync daemon linking Home and Redtop branches over Tailscale WireGuard mesh, querying RouterOS user directories and reconciling credentials.
• Dedicated 3D printing station with a Tapo C100 RTSP camera feed and automated 1080p timelapse capture via ffmpeg with slicer-coordinated auto-stop timers.
