about me

As the Head of IT at SIUT, a cutting-edge Berlin-based company revolutionizing and digitalizing concrete architecture, I am fueled by a passion for software development and take pleasure in constructing intricate systems. With a programming career that began in 2013, I had the opportunity to collect a lot of experiences and skills.

freelancing
With my freelance company, nosc.io, I've had the privilege of collaborating with esteemed clients such as S-Bahn Stuttgart, Filmhochschule Ludwigsburg (developing their ticketing and event management system), and real estate firms like Verwaltung Bauer.
volunteering
Since 2019, I've applied my digital and tech skills to assist non-profit organizations. I've been part of a team that developed infrastructure for a notable climate movement in Germany and have helped smaller organizations and art collectives build websites, tools, and apps, allowing them to focus on their primary objectives.
skills
I started building iOS apps in 2014 and have been doing that since. But this is not my main focus anymore. I am now a full-stack typescript developer with a focus on the backend, but I am also very comfortable with C and C++ (especially C98) as I attended the well known 42 coding school, where you build core functionalities like shells and web servers from ground up. I daily drive Typescript and Angular, but of course worked with other technologies. This website is build with next.js. In the following I want to draw a picture of what I can do and whatnot.
web development / backend
I have developed and planned a wide range of web systems, from independently creating an asset management system to collaborating on comprehensive event management systems for the FMX conference. I've also catered to clients' specific needs, such as the development of druckation.de, a platform that facilitated connections between students and a professional financial advisor comapany (promotion ended, no longer available).
low level development
At 42heilbronn, I was working with C and C++ on a daily basis. I was building core functionalities like shells, web servers or ray casters. Find them on my GitHub! I am very comfortable with C and C++ and I am able to build complex systems with it.
app development
In my spare time, I enjoy developing iOS apps. My most significant and oldest creation is HITS DB (iOS only), an app originally designed to address my mom's histamine intolerance. It has since garnered over 10,000 users. I hope to dedicate more time to its development soon. In total, I've built over 30 apps, with approximately a dozen created for clients or professional projects.
consultation
I am a consultant for two app agencies and help them occasionally with their projects. I consult NGOs for free in my spare time. If you are interested in my consultation, please contact me.
system planning
At SIUT, I plan out systems, consult with the team on how to build them and build them. You'll see stuff of what's coming soon. Stay tuned on that - it's really cool!
