open for the right team

I turn “what if” into something you can log into.

Simon here. Twenty-plus years of shipping software — online stores back when that was a novelty, SaaS tools today, AI wherever it actually earns its keep. I like taking a rough idea, writing the first commit, and not stopping until real people are using it. And paying for it.

Two decades, one running build.

Everything below actually happened, in roughly this order.

Ideas that made it to production.

One flagship, a handful of side builds, and the infrastructure holding it all up. Click any screenshot to see it up close.

Tipptreff.app

live

A prediction & gamification platform for friends, family and colleagues — idea, planning, coding, infrastructure and the customer service around it, all mine. Still in active development, still adding features people actually asked for.

  • AI league curator — describe your league in one sentence, get a draft back
  • Live scores — the minute ticks, points and table update while the match runs
  • Share cards — tip sheet to WhatsApp or story, invite code and QR included
  • Money pool — the coffee fund with a league table (the app never holds a cent)

Payroll Manager

beta

Hourly tracking and expense reconciliation that doesn't make anyone dread payday. Version 2 speaks English and German, and its login screen is already prettier than most dashboards I've shipped.

Family Child Care Manager

alpha

Keeps a family childcare setup off sticky notes and group chats: one shared calendar, open slots that people can take over, and a dark mode for the late shift. Alpha, but already earning its keep.

SaaS MVP

ShareCart

side

A shopping list you can actually share: tag who brings what, assign items, keep quantities and notes in one place. Built for the kind of party where nobody knows who has the raclette grill. Small on purpose.

Nextcloud setups

Self-hosted Nextcloud instances, set up and kept alive on my own and customers' VPS boxes.

Store setups & connectors

Magento, Shopware, xt:Commerce — plus the connectors that get shop and shipping systems talking to each other.

I can build it. I need someone who can sell it.

Let's be honest about the missing puzzle piece. I love pushing projects forward, and I'm good at it. What I need next to me is a strong sales mind — plus backoffice, finance and marketing support, so the whole picture finally clicks together.

DONE Build That's me. Product, code, infra, AI.
WANTED Sales Someone who loves bringing it to customers.
WANTED Marketing Make people notice it.
WANTED Finance Numbers, tax, cash flow.
WANTED Backoffice Admin that just runs.

Sales first. Marketing, finance and backoffice are the frame around it — the pieces that free me up to do what I do best: build.

Let's talk

Honesty. Clear communication. Passion.

That's what I bring — and what I expect back. Here's the fine print for whoever I build with next.

What gets me up in the morning

  • Building something with a team that people actually pay for
  • Not just writing the software — helping get it in front of customers too
  • Anything involving AI, coding, or turning a mess into a product

What I'm looking for

  • A long-term project — building a genuinely valuable solution together with people who are as passionate about it as I am
  • A strong sales mind who loves bringing products to customers — the missing puzzle piece
  • Marketing, finance and backoffice people who own their turf, so I can keep building
  • Communication that's honest and direct by default — no guessing games
