SAP Software Developer · Lucerne, Switzerland

Hi, I'm Gian Federspiel.

I build enterprise SAP applications and ship web & mobile products — bridging hands-on software development with the IT project-management side of delivery.

4+ years developing SAPUI5 & SAP Fiori applications at Suva in agile teams, now studying International IT Management (BSc) at HSLU.

01 — About

Profile

Junior Software Developer with a Swiss Federal Diploma (EFZ) in Application Development and 4+ years of hands-on experience building enterprise SAP applications in agile teams.

At Suva I develop and maintain business applications with SAPUI5 and SAP Fiori, implement REST / OData services, and contribute to the migration from SAP CRM to S/4HANA. I work the way modern enterprise teams do — Scrum and SAFe, requirements engineering, stakeholder coordination, code reviews and testing.

Outside of SAP I build web and mobile products with JavaScript / TypeScript, Node.js, React and React Native, and I'm increasingly focused on integrating AI into real products. I'm currently studying International IT Management (BSc) at HSLU, sharpening the bridge between software development, digital transformation and IT project leadership.

04 — Projects

Selected Projects

HomeBite

React Native · Expo · Supabase · Claude AI

A cross-platform food-inventory app that cuts down on food waste: track what's in your kitchen and its expiry dates, then get AI-generated meal suggestions based on what you already have.

What it does
Expiry tracking with AI meal suggestions, fast item entry via receipt scanning and voice, and sign-in with email, Apple or Google.
How it's built
Expo / React Native app on a Supabase backend (auth, Postgres, edge functions), Claude proxied through an edge function, and a Liquid-Glass UI built with expo-blur.
What I learned
Wiring an LLM into a real product end to end, integrating camera and voice input, and shipping a tested mobile app with EAS and CI.

Strava Dashboard

Node.js · Express · Vite · Strava API

A personal dashboard that pulls in my own Strava data and shows weekly and monthly training stats, route maps and workout details in one place.

Why I built it
Wanted a cleaner overview of my training than the Strava app gives, and an excuse to work the Strava API end to end.
What I learned
OAuth flows and token refresh, building a small Node/Express proxy to keep secrets off the client, and wiring it together with a Vite frontend.

Story Poker

S/4HANA · SAPUI5 · WebSockets

A real-time planning-poker tool for sprint refinements: teams join a shared room and vote on ticket complexity in story points, keeping estimates live and in sync across the session.

What it does
Create a room per team, configure votable values, and run live estimation rounds. It aggregates each round to suggest a value and shows how everyone voted — or hides it for anonymous confidence votes.
My role
Designed and built the whole tool solo, from the room model and configuration UI to the real-time voting flow, deployed for internal company use.
What I learned
Using WebSockets to keep every participant's view in sync in real time, and modelling multi-team rooms with configurable voting options.
