Softwarewith substance.
For 10+ years I've been building web, backend and embedded software. I take projects from architecture all the way to production.

01 — Services
From the first data model to the pipeline that ships every commit: I work across the whole stack and speak the language of product, engineering and operations.
Complex web applications from database to interface, scalable, maintainable and testable.
Clean APIs, well-designed data models and fast queries are the foundation of data-driven products.
With automated pipelines, containers and reproducible environments, releases become routine instead of risk.
Software close to the hardware: embedded Linux systems, microcontrollers and connecting devices to the cloud.
LLM features, semantic search (RAG) and automations, integrated sensibly into existing systems with privacy in mind.
Code reviews, architecture workshops, legacy modernisation and mentoring: a second opinion backed by 10+ years of practice.

04 — Journey
Hi, I'm Florian. I studied computer engineering at Beuth University of Applied Sciences in Berlin. Since then I've been working between embedded systems and the web, as a freelancer since 2018. Away from the keyboard: guitar & bass, skateboarding, table tennis and travelling.
Apr 2013 – Apr 2018
Computer engineering studies
Software, hardware and everything in between: the foundation for my work between embedded systems and the web.
2015 – 2016
Full-stack developer · Freelance
A mobile app for monitoring a larger photovoltaic system, one of my first freelance projects, alongside my studies.
2016 – 2018

05 — Approach
Clear communication, short feedback loops and code your team will still enjoy touching two years from now.
Clarify goals, users and constraints. We work out what is really needed and what is not.
Architecture, data model and milestones, with every decision documented and justified.
Iterative short cycles with tests, code review and regular working increments.
Deployment, monitoring and handover. If you'd like, I'll keep supporting the project afterwards.
Remote or on-site
Remote across Germany, Austria and Switzerland, on-site in Potsdam, Berlin and Brandenburg.
AI-assisted development
I use AI tools every day as an amplifier for 10+ years of engineering experience, not as a replacement for it. The result is faster iteration at the same quality.
01
System design, data models and trade-offs come from experience, not from a prompt.
02
AI-generated code goes through the same review, typing and linting as any other code.
03
Automated tests and CI make sure that fast stays correct.
04
No client code goes into third-party tools without approval. Local and EU options are available.
More time for the hard problems, faster iterations, the same level of care.

My office is in Potsdam, half an hour from central Berlin. I'm happy to come by for workshops, kick-offs or pair programming. Everything else we handle efficiently remote.
