01 / Selected work

What is live.
What is moving next.

Each project names its state, my role and the proof that exists today. Private builds stay private without pretending the work is invisible.

01Shipped

Document operations

Tagvico

Current release · v3.1.2

A self-hosted companion for Paperless-ngx that turns documents into clean metadata, persistent research conversations, assigned actions and recoverable automation.

Built for: Important follow-ups disappear inside document archives, while fully automatic AI filing makes mistakes difficult to audit.
My role: Product, design, full-stack engineering and operation
Verified: July 2026

02Android beta

Mobile health beta

Daystrong

Android beta · Beta 1.1.23

A mobile-first nutrition and strength companion combining meals, AI-assisted macro capture, training routines and progress in one account-backed product.

Built for: Food tracking and strength training are often split across disconnected apps that make a consistent daily routine harder to maintain.
My role: Product, mobile app, API and release engineering
Verified: July 2026

03Private build

Household system

Tevori

In active development

One shared source of truth for household inventory: shopping adds stock, recipes calculate shortages, and cooking deducts ingredients with units.

Built for: Inventory, shopping and recipes usually live in separate tools, so every household action creates more manual reconciliation.
My role: Product strategy, interaction design and full-stack engineering
Verified: July 2026

04Private build

Hospitality platform

Savelo

Launch gates pending

A multi-tenant website, operations and sales platform for Swiss hospitality teams, currently being rebuilt around a focused restaurant workflow.

Built for: Restaurant websites, menus and daily operations are often managed across disconnected tools with repeated content and administration.
My role: Product design, platform architecture and full-stack engineering
Verified: July 2026

not vanity metrics.

19 JUL 2026Savelo · Studio rebuild

03 / Range

One builder.
The whole product loop.

I'm a third-year Informatiker EFZ apprentice at CKW / Axpo, building reliable business applications while developing products of my own.

The breadth is deliberate: product judgment, application engineering and operating the systems all sharpen each other.

04 / Build something useful

Have a problem worth
shipping?
