Who I am

Hi, I'm René! I'm from Hamburg, Germany.

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.

Work
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. After various freelancing gigs, I am now the Director, Engineering of ConnectedHealth, also fully remote. Since 2019 I'm 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

Riding motorcycles, skating, cycling, running, hiking, camping, swimming, kayaking
Playing guitar, cooking and gardening
Scuba diving: currently a PADI Divemaster (#408408) & Technical Diver
Skydiving (NZPIA B-License) & Paragliding (IPPI-3 / PG-2)
Ham Radio: KN6DZC
Maintaining several blogs and websites
Creating and contributing to free software
Education: Taking MOOC & language classes, watching Laracasts, reading or listening to podcasts

Memberships

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

Travel
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. I write about my travels on my Instagram and Travel Blog.

repat.de - my blog

On my personal blog I've been writing about programming, Linux and all things tech for over 15 years.

webchangedetector.com - visual regression testing

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 you what changed. I rewrote the backend and API as a Laravel app.

droid-break.info - high quality open source Android apps

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