About Me

Who I am

Hi, I'm René! I'm from Hamburg, Germany though I work and/or travel around the globe at the moment.

What I do

Academic Background
I hold a Bachelor of Science degree in Computer Engineering from the University of Applied Sciences in Hamburg. Instead of specializing in one topic, I chose a variety of courses such as IT security and database design.

During college, I started working for a German-Norwegian eCommerce startup as a software engineer for ~4 years. In 2018 I started working on a variety of projects and contracts as the Director of Engineering at Bertholf Ventures, mainly as the CTO and CoFounder of DIYDIFM/marketAIng and as the CTO for hire of Kndrd. At the beginning of 2019 we went through a Techstars program in Amsterdam. I'm also a Certified Laravel Developer.

I have multiple years of experience in the following areas:

  • Data modeling and database design for relational and NoSQL databases
  • Software Architecture and Security for SaaS
  • API Integrations
  • Technology stack: PHP (Laravel), JavaScript, Java and Python
  • Process BI information
  • Server Administration and DevOps/CI/CD
  • Working 100% remote, no fixed office
  • Coaching new employees and oversee freelancer work

When I'm not working I enjoy

  • Active contributor to the German Wikipedia and other Wikimedia projects since 2006
  • Contributor to OpenStreetMap and Transifex (Open Source Translation)
  • I regularly go to (Tech-) Meetups in whenever I stay in big cities
  • For the past decade I've attended a variety of tech conferences such as the CCC in Germany

I enjoy traveling, especially by bike or on foot, meeting new people and exploring foreign cultures and cuisines. I plan to visit every country eventually, see travel section.

Projects (excerpt) - my blog

On my personal blog I've been writing about programming, Linux and all things tech for over 12 years. - automated screenshot comparison

When updating WordPress websites, it happens all too often that things break. This tool takes screenshots before and after an update, compares the screenshots and tells what changed. I rewrote the backend and API as a Laravel app. - high quality open source Android apps

Inspired by I created Droid-Break to list high quality alternatives to the big proprietary solutions. The source code is available on GitHub.
