Let's talk

Artur Ferreira · Switzerland · Product builder


Application developer shipping focused products from decision to verified release — Tagvico is shipped and stable, Daystrong is in Android beta, and Tevori is being rebuilt UI-first. From September 2026 I'm also building a venture in the Youngpreneurs Zentralschweiz founder program.

(04) — Range


I'm a fourth-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.

01
Product delivery

Discovery, interaction design, implementation, deployment and iteration across one accountable loop.

02
Application systems

.NET business applications at work; Next.js, TypeScript and mobile products outside it.

03
Data and AI

PostgreSQL, SQLite, Convex and approval-aware AI workflows built around real product constraints.

04
Infrastructure

Containerized apps, reverse proxies, storage, identity and production-style self-hosting.

Clear status. Real artifacts. No invented traction.
