IT professional based in North York, Ontario, Canada — building reliable systems, automating workflows, and running a self-hosted homelab 24/7 on a Raspberry Pi 5.
About Me
I am an IT professional with over 20 years of hands-on experience designing, implementing, and maintaining enterprise systems. My career spans database administration, backend development, infrastructure engineering, and modern DevOps practices.
Fluent in English, Spanish, and Portuguese, I bring a collaborative and cross-cultural perspective to every team. I am passionate about automation, reliability, and building things that run unattended — like this very server.

A Python-based automated trading system that runs 24/7 on this Raspberry Pi 5. It performs real-time market analysis, executes trades based on configurable technical strategies, manages position sizing, and logs all activity for review. The system handles connectivity resilience, automatic restarts, and sends notifications on key events.
View Write-up & DashboardA self-hosted infrastructure built around a Raspberry Pi 5 as the main server and a Raspberry Pi Zero 2W as a lightweight monitoring node. Services include an OpenClaw AI agent gateway orchestrating local services via MCP (finance, career, trading), Apache2 with SSL (this site), WireGuard VPN for secure remote access, automated encrypted backups, cron-based monitoring, and a custom metrics API that feeds this live dashboard.
View Agents & ArchitectureAn automated pipeline running on a Raspberry Pi 5 that monitors official RSS feeds from Claude, Gemini, OpenAI, Python, VS Code, and Ollama every 3 hours. Generates AI-curated summaries with content-type classification (release, news, research, update), then publishes to the portfolio. Notifies Google Search Console and Bing Webmaster Tools on each update.
View ProjectReal-time sky map for North York, Toronto. A Raspberry Pi 5 computes positions of the Sun, Moon, planets, and bright stars every 3 minutes using the Skyfield astronomy library and DE421 ephemeris, then publishes the data as JSON. An interactive Canvas renderer with gnomonic projection displays the sky from any azimuth, elevation, and field of view.
View ProjectReal-time aircraft tracking over Canada powered by a Raspberry Pi 5 that fetches live data from the OpenSky Network API every 10 minutes using OAuth2, then pushes it to the web server. A Leaflet.js interactive map and Chart.js analytics run in the browser, while an Oracle APEX dashboard backed by Oracle Autonomous Database provides SQL-driven historical analysis.

Real-time telemetry from the self-hosted Raspberry Pi 5 and its peripherals — the same hardware serving this website and running all backend services around the clock.
Real-time metrics updated every 30 seconds.
Real-time system metrics from the lightweight monitoring node.
Live readings from a BME680 sensor: temperature, humidity, pressure, and air quality.
Live Security
This Raspberry Pi 5 is publicly reachable and gets scanned and attacked constantly. These are the real numbers — SSH intrusion attempts blocked by fail2ban, IPs currently banned, and genuine human visits — updated every 15 minutes.
