About Sebastian

Many small businesses have processes that are still manually transferred from one point to another. This costs time, and every change needs to be tracked everywhere. What's usually missing is not a major digital overhaul — but someone who makes everyday life easier with a few targeted adjustments.

That's exactly what I do: I translate manual processes into a clear digital structure, individually tailored to your business. It's important to me to meet you where you are — whether you're tech-savvy or still stuck in your old ways. I'll take you along and make it clear how much easier it becomes.

My approach to technology comes from playing live electronic music. Behind every performance, there's a precisely programmed framework: playback and clicks synchronized to the beat, while lighting, visuals, and the mixing console react to the right moment via timecode and MIDI simultaneously. A single trigger starts an entire chain — next scene, console, lighting, and loop at the same time, in the exact order, without anything faltering. I use this exact thinking in processes and automation in software development today.

I've built what this looks like with Flowgigs — a web app our band (GbR) uses to handle all its organization. Everything used to be coordinated manually; now everyone quickly sees the information they need, and it updates automatically as soon as something changes. Notifications run through the channels already in use — Telegram or email — no additional tool that no one opens.

What I can help you with:
• Custom web tools & small web apps (Node.js, JavaScript)
• Information centrally, up-to-date, and quickly accessible to everyone
• Notifications via existing channels (Telegram, email) — no new tool needed

I work with AI support — making it fast and affordable. I'm at the beginning of my freelance career; in return, you get high commitment and fair prices. Let's talk about your project.

Experience

  • Selbstständig – Eigenprojekt Flowgigs
    Fullstack Developer – Flowgigs (SaaS for Band Management)
    March 2026 - Today (4 months)
    Leipzig, Germany
    As an active musician, I built a web platform out of necessity to automate band booking and organization — from inquiries, contracts, and travel planning to accounting.

    As a fullstack developer, I am responsible for the entire project:
    • Backend with Node.js/Express and SQLite
    • Responsive Single-Page Frontend (HTML/CSS/JavaScript)
    • Multi-tenant architecture for multiple bands on a single codebase
    • Automations: Telegram bot, email reminders, calendar feeds (iCal), Google Sheets/Drive integration
    • AI-powered features for automatic capture of gig and logistics data

    The project is developed with AI support and is continuously being expanded. It demonstrates my pragmatic approach: I analyze the specific workflows of a small organization and automate them individually.

    Freelance Musician (Drums, Live Electronics)
    September 2006 - Today (19 years and 10 months)
    Leipzig, Germany
    Since 2008, I have been a full-time freelance professional musician (Diploma Musician, Franz Liszt University of Music Weimar) — drums and live electronics with Ableton Live in bands, theater, and variety productions (including Krystallpalast Varieté Leipzig, The Beefees, Friedrich Rau).

    As a freelance musician, I have been independently organizing projects, appointments, and clients for over 15 years — reliably, structurally, and on time. Live electronics with Ableton (live looping, lighting control) was also my entry into technical/digital work, which later led to software development.
