2025About me
My name is Samuel Gfeller, and I help people and companies optimize their business workflows by developing tools and services tailored to their needs.
I completed an apprenticeship as an application developer (VET
Diploma)
in 2020.
Since then,
I've spent over five years independently researching and studying how to build performant,
full-stack web applications with modern technologies, always aiming to do so in the most efficient
and maintainable way possible to create scalable SaaS.
An Open Source template emerged out of it and a documentation that summarizes the key lessons.
I also love to physically use my hands to build and repair things or just have fun. I like challenges and learn or improve on skills. Making music, juggling, calisthenics, and gardening are some of my hobbies.
On the farm I grew up, I had a lot of fun learning about construction, machine repair, electricity, working with wood and metal, cultivation, animal care, and much more.
