Software engineering portfolio
Hi, I’m German.
I build ideas into
working software.
Exploring full-stack development, useful tools, and the systems behind them.

Putting the pieces together with JobLedger
Building JobLedger gave me hands-on practice connecting a React and Next.js interface to Supabase authentication and a PostgreSQL database. I worked through company workspaces, owner and employee access, inventory transactions, job costs, CSV exports, and deployment to a custom domain. I also built a public demo so visitors can explore the application without an account.
The portfolio
Built to solve. Made to learn.
A closer look at the projects I’m building and the thinking behind them. Open a project to see its details, real application screenshots, and live demo links. The matrix and resource projects include interactive concept previews.
A little context
Curiosity, with follow-through.
I’m German Antonelli, a computer science student in San Jose working toward a career in software engineering. I like breaking problems into smaller pieces, understanding why a solution works, and turning ideas into things people can use.
From operations to software
Building on practical experience
Leading construction crews and managing a retail team taught me to coordinate people, keep track of details, and solve problems under changing conditions. Those experiences now inform the tools I’m building.
Learning through real projects
My portfolio connects a static frontend to a Spring Boot API. With JobLedger, I expanded into React, Next.js, Supabase authentication, and PostgreSQL, connecting inventory and job costs in company workspaces. Building a public demo also taught me how to make the application accessible to visitors while keeping saved workspace data behind sign-in.
