Manuel Weber builds solutions.

I gather what my customers need and build the solution together with my team, guiding and organizing the whole process. From infrastructure to software.

About

“Communication is key — let's shape the future of IT together.”

Coming from software and backend development, I like to make sure that the systems we build are what the customer actually wants. From a young age I was interested in how things work: I was the annoying kid that asked why, to the detriment of parents and teachers — that's when I wasn't singing. Luckily for my colleagues I liked to share my knowledge and homework, and studied together with them for exams. As I liked to tinker, I went to HTL Bulme and learned electrical engineering there, with a special focus on English and project management. While I had learned some programming before, it was there that I actually started to love coding and solving the little puzzles that come with it.

The next logical step after that was studying computer science. During my years at TU Graz I worked as a studying assistant — I loved teaching then and I still love it now — and majored in IT-Security and Internet of Things. After finishing my studies I started working as a backend developer and quickly drifted towards a more customer-oriented role: project management and technical sales. There my love for teaching — or in this case, translating complex topics — and for sitting down with a topic I know little to nothing about came in handy when talking to customers who had deep expertise in their field, but didn't know software development.

Today I am still true to my love for technology and passing on my knowledge. At RiKuWe, which I founded in 2025 with Christian Rieger and Thomas Kugi, we build cloud infrastructure without lock-in effects: I build products with Thomas and Chris, and I do the sales and requirements engineering. At Fraiss IT I build solutions with my team, combining requirements engineering, project management, and sales. And in the local community I go to events concerned with technology and software development — I'm now a regular at the Linux Cafe, where we help users set up a Linux distribution so they don't have to throw away perfectly good hardware that has been obsoleted by Windows.

Now

Co-founder · 2025 – present

RiKuWe GmbH

Cloud infrastructure and managed hosting without lock-in effects, founded together with Christian Rieger and Thomas Kugi. Reliable, scalable, GDPR-compliant — and thought through before it is built. I build products with Thomas and Chris, and I do the sales and requirements engineering.

Solutions Architect & PM · 2018 – present

Fraiss IT GmbH

I build solutions with my team, combining requirements engineering, project management, and sales — from the first meeting with a customer to the running system, across fields like sanitation, micro public transport, and mobility at higher ages.

Regular · Graz

Linux Cafe & community

I go to local events around technology and software development, and I'm a regular at the Linux Cafe: we help users set up a Linux distribution so perfectly good hardware, obsoleted by Windows, doesn't end up in the bin.

Music

I mentioned that I used to sing — that's not really true, though: I still do.

Vocals · Band lead · Active

Gwendolin

A fresh take on folk rock. I sing, and I lead and organize the band together with Richard Diesterbeck — somewhere between an Irish pub, the Alps, and the streets of Graz.

Vocals · Currently resting

A Few Mistakes Ago

My former band is taking a break after two awesome albums, Mistakes Were Made and Golden Mistakes — check them out on YouTube and Spotify.

Behind the microphone there's a decade of vocal coaching — and away from it I'm an avid social dancer, these days focusing on West Coast Swing.

Writing

I write on the RiKuWe blog — mostly about the ideas behind good infrastructure, and how to talk about them.
