Hi, my name is Klaus Breyer.

Klaus Breyer

I am a CTO and Startup Founder/Advisor, living in Berlin.

I started the social media agency buddybrand and the Influencer Marketing Software BuzzBird some time ago.

Currently I am fighting climate change, by working on how Software Engineers can understand and reduce their co2 footprint and I plan to start a slow business in this area.

Craft

I build full stack products by myself and also lead whole teams with the responsibility for product and technology.

For startups in the scaling phase, I am available as an advisory board member or as interim CTO.

I am a mentor and coach to Software Engineers and first time startup founders.

I do not only build software – I take ownership: For business model, product and technology.

Development

When building stuff by myself, I prefer serverless with NodeJS, supplemented by JAM Stack (vanilla Javascript / react / material ui). But I am also experienced with PHP (WordPress / Symfony) and Ruby on Rails in Production.

My Stack is optimized for fast prototyping / goto market while having a lot of experience with the integration of other services: Facebook Graph API (Insights, Pages, .. – I even wrote a book about it!), Instagram Analytics API, YouTube Analytics API, Twitter API, Github API, Sign in with Google, Stripe, Paddle, Firebase – and of course AWS: IOT Core, SQS, SNS, RDS, s3, STS, IAM, SES, Route53, Cloudwatch, Cloudfront, Elastic Beanstalk & Cloudformation.

Philosophy

Good software is always used but never finished.

The goal is to always build the next v01. In software and in life. Zen philosophy puts it like: Nothing exists in its present form or color except in this moment. A beginners mind is free of any possessions, as it knows that all is in a state of fluid change.
