I’m a software engineer focused on building real-world systems, especially around backend, event-driven architectures and hardware integration.

• ❤️ Building things that actually impact people
• 🐧 Linux, open source and low-level systems
• ⚙️ Simple systems that solve real problems
• 🔌 Connecting software with the physical world

• Backend development (Scala, APIs, event-driven systems)
• Experimentation with embedded systems (ESP32, Raspberry Pi)
• Building personal tools and systems from scratch

• Vortex: A real-time animation system running on Raspberry Pi with LED matrix + audio, reacting to Spotify playback events.
• LifeDashboard: A personal backend system (Perl/Dancer2) designed to feed data to low-power devices (ESP32 + e-ink dashboards).
• Perl-Vibes: A vibe-driven music recommendation engine in Perl that maps free-form text into emotional dimensions (valence & arousal) to suggest songs.
