About Tobias

I develop the software your company really needs - no off-the-shelf standard solution, but systems that precisely match your business logic.

With over 13 years of experience and 90+ completed projects, I help companies automate manual processes, break down system silos, and build scalable backoffice solutions.

My focus is not on writing code - but on solving real business problems: **saving time**, **reducing errors**, and **clean architecture**.

You work directly with me - no account manager in between, no onboarding time, no ancillary wage costs.
In return, full commitment to milestones and deadlines.

What I implement for you:
Process automation · API integrations · Custom backoffice systems · E-commerce solutions · Native & Web apps
