I'm an Aerospace Engineering student and open-source developer interested in understanding how complete systems work — from user interfaces and application architecture down to operating-system services, networking and hardware integration.

I enjoy projects where engineering and product design meet.

Rather than building isolated prototypes, I tend to work on complete ecosystems:

• 🐧 Linux desktop environments and operating-system integration
• 🎨 Native creative software
• 🏠 Home Assistant and smart-home systems
• 🍎 Apple ↔ Linux interoperability
• 🌐 Networking and self-hosted infrastructure
• ⚡ Performance profiling and optimization
• 🧪 Automated testing and CI
• 🔗 Cross-device and cross-platform workflows
• 🛰️ Aerospace, GNSS and numerical engineering

My general philosophy is simple:

Build it. Understand it. Measure it. Improve it.

Nodalix OS is a cohesive Arch Linux desktop built around Hyprland, Wayland and QuickShell.

The project treats the desktop as one integrated system rather than a collection of unrelated dotfiles and utilities.

• Nodalix Shell — custom QuickShell/QML desktop interface
• Nodalix Apps — application management and integration
• Phone Link — native iPhone integration
• Nodalix Updater — system and release management
• Nodalix Installer — installation and deployment
• Nodalix Release — versioned system definition
• Nodalix Wallpapers — visual identity and desktop assets

Nodalix includes its own Phone Link implementation for iPhone.

It works with technologies including:

• ANCS / Bluetooth LE — notifications
• MAP / OBEX — messages
• PBAP / OBEX — contacts
• HFP / oFono — calls and hands-free integration

The goal is to make iPhone integration feel like a native part of the operating system, rather than a separate utility.

Nodalix also works on:

• integrated system updates
• stable and preview release channels
• Arch package updates
• application updates
• firmware updates
• hardware-aware optimizations
• Bluetooth
• PipeWire audio
• networking
• notifications
• media controls
• desktop search
• system settings
• recovery paths
• security
• gaming integration

Nodalia Cards is a cohesive, app-like card system for modern Home Assistant dashboards.

Rather than treating every card as an independent component, Nodalia uses shared design principles, interaction patterns, editors and architecture across the entire suite.

• responsive card layouts
• optimistic interactions
• fluid animations
• visual editors
• mobile-first interfaces
• theme-aware surfaces
• shared design tokens
• localization
• lazy loading
• automated testing
• reusable architecture
• performance-focused rendering

The suite includes cards for:

• lights
• climate
• covers
• locks
• alarm panels
• media players
• cameras
• vacuums
• weather
• calendars
• graphs
• power flows
• rooms
• people
• scenes
• notifications
• navigation
• favourites
• gauges
• news
• entities
• fans
• humidifiers

Nodalia Cards is available directly from the official HACS catalogue.

Nodalia Cards Engine is the optional backend companion for Nodalia Cards.

It enables functionality that needs to continue running even when no dashboard is open, including advanced shared state and background features.

Nodalia uses a self-hosted Weblate instance for collaborative translations.

A major engineering focus is interoperability with layered Photoshop documents.

Lienzo works on:

• PSD
• PSB
• editable text
• masks

PSD · PSB · PNG · JPEG · TIFF · WebP · BMP · TGA · GIF · SVG · Aseprite · JPEG XR · Camera RAW

and additional import/export workflows.

Lienzo includes a native Model Context Protocol connector and JavaScript scripting environment.

This allows local automation tools to work with editable documents rather than relying only on screenshots or flattened files.

Capabilities can include:

• inspecting document structure
• reading layer information
• creating layers
• editing text
• manipulating shapes
• selections
• brush strokes
• filters
• exports
• saving editable documents

Vinilo is a native GNOME music player for Linux written in Rust, GTK4 and libadwaita.

Its goal is to provide one native desktop experience for multiple music sources without simply wrapping a website inside a window.

Vinilo currently works with:

• music library
• artists
• albums
• playlists
• queue
• lyrics
• karaoke
• crossfade
• listening statistics
• optional Last.fm scrobbling
• media keys
• lock-screen controls
• desktop integration
• background playback

Vinilo separates the UI from the playback engine.

The GNOME application and its terminal client aguja communicate with the same backend, allowing music to continue playing even when the graphical window is closed.

I prefer explicit responsibilities, reusable components and clear boundaries over feature code that becomes progressively harder to change.

I like profiling actual bottlenecks instead of guessing.

That includes work around:

• rendering pipelines
• caching
• dirty regions
• lazy loading
• DOM updates
• compositing
• desktop responsiveness
• memory usage
• startup performance

Performance also needs to be perceived.

Good software should respond immediately through:

• optimistic state
• predictable interactions
• fluid motion
• clear feedback
• consistent controls

Tests and CI are part of the architecture.

I use them to make refactors safer and prevent fixed bugs from quietly returning later.

The goal is not only to make software work today.

It should still be understandable and extensible after hundreds of commits.

I particularly enjoy making systems that were not designed for each other work together cleanly.

Right now I'm mainly working on:

• evolving the shell
• Phone Link
• Apple / iPhone integration
• system updates
• security
• performance
• native applications
• cohesive desktop UX

• next-generation Nodalia Cards architecture
• Nodalia Cards Engine
• performance
• testing
• translations
• Home Assistant integrations

• rendering performance
• editing workflows
• PSD / PSB compatibility
• native interface work
• automation
• MCP integration
• creative-tool architecture

• streaming-source integration
• GNOME UX
• playback architecture
• desktop integration
• local music
• background playback

• CAD
• vector graphics
• web browsing
• Linux-native software
• smart-home tools
• Apple interoperability

Most of the software I build is developed publicly.

I value:

• bug reports
• technical discussion
• code review
• testing
• translations
• design feedback
