About
Architecture. Interface. Impact.
I'm Felix Schattenberg, a full-stack developer running a small business in Dresden. I build products focused on stable Laravel backends, fast interfaces, and decisions that still make sense in production — from the first concept to ongoing support.

How I work
Direct line
I typically work on a project alone — a single point of contact from the first inquiry to handover, with no handoffs between teams.
Progress updates, not a black box
Regular, traceable progress instead of a surprise right before delivery — I document decisions instead of making them silently.
Operations built in
Code that stays maintainable after handover: tests, deployment process, and monitoring are part of the project for me, not an optional add-on.
Honest assessment
If an idea isn't technically sound or a scope doesn't fit my profile, I say so in the first conversation — not after the contract is signed.
