Developer and creator of cute & functional applications. I build things at the intersection of rigor and curiosity.
I'm Dehlya — a full-stack / creative-coding engineer who fell in love with code in 2021. By day I'm finishing my Bachelor in Business IT. By night I build web apps, design systems, and anything with the suffix Flow.
I experiment with WebGL, music-focused UIs, and creative interfaces. I love adding the suffix "Flow" to my projects — smooth, intuitive experiences are always the goal.

I'm fascinated by systems.
Whether it's a race car, a design system, a data pipeline or even a garden, I end up asking the same questions:
How does it work?
Why does it behave that way?
Can I make it simpler?
That's what naturally drew me towards software. Every project on this site is a different answer to those questions.
The domains keep changing. The instinct doesn't.
I like building systems that make complicated things feel simple.
Telemetry. Design systems. Data engineering.
Different projects. Same thread.
49 downloadable CSS themes as a design system
AuraFlow is a library of 49 ready-to-use design system themes, delivered as CSS custom properties. Each theme is a complete set of 23 design tokens — colors, typography, spacing, shadows and more — so you can drop one in and your entire UI adapts. It started as something I built for myself in 2024: I love making themes but never have time to design one from scratch mid-project, and not every developer is a designer. Free and open source, it installs in about 30 seconds via npm or CDN. Launched with 46 themes, now 49 and counting.
Smart-apartment IoT pipeline at real scale
An end-to-end data engineering project built on real IoT sensor data from two smart apartments in Switzerland — turning hundreds of thousands of raw sensor files into clean, business-ready dashboards.
Real-time car telemetry for Formula Student
Live and asynchronous telemetry system built for the Valais-Wallis Racing Team — streaming data straight off the car so engineers can read its behaviour in real time, then dig back into every lap once the dust settles.
An interactive lab for auditing passwordless authentication
Passkeys Lab is an interactive tool for seeing how passwordless authentication actually works. Instead of treating WebAuthn/FIDO2 as a black box, it makes the cryptographic handshake visible in real time — every challenge, signature and origin check — so you can watch a passkey login happen step by step. I built it for an IT Security course, but the real goal was my own: to understand a protocol by rebuilding it, not just reading the spec.
A music player built around personalization.
CosmicFlow started from a very simple frustration: every music player expected me to adapt to it. I wanted the opposite. Instead of deciding how people should experience their music, CosmicFlow lets every user shape the player around the way they naturally listen. Themes, layouts, playback views, colours and interface density can all be adjusted until the application feels like your own rather than somebody else's. I originally built it for myself. Over time, it naturally became my everyday music player—and the place where I experiment with interface ideas before they find their way into other projects.
Alongside my studies I volunteered with EPFL & HES-SO outreach programs, running workshops to encourage young girls to discover IT and write their first lines of code.
Based in Valais, Switzerland. Always happy to talk code, projects, or ideas.
