My work at trivago involved the following tasks:* Maintain our fully containerized infrastructure.* Build systems that work reliably and run at scale.* Advice teams on how to create robust web-services and follow the best practices (e.g. twelve factor app, continuous integration, testing,...)* Help make sure that our data pipelines keep working reliably in our multi-cloud infrastructure (GCP, AWS, Nomad).Key areas of responsibility:* Maintaining trivago's Docker image infrastructure.* Built and shipped tools for orchestrating and monitoring Docker containers at scale(in Go and Rust).* Hands-on knowledge on Google Cloud and the HashiCorp stack (Nomad, Consul, Vault).* Advocate and advisor for Open Source development* Co-maintaining the trivago techblog and its infrastructure* Developer-relations with other companies and external usergroupsIn my spare-time, I ran a YouTube channel about Rust development (https://hello-rust.show/).I also gave workshops for beginner and intermediate Rust programmers.

At trivago I worked as a Senior Backend Engineer on the Website Performance team.On a daily basis I focused on improving site reliability and response times of our various services (such as our core product, the hotel search). I helped scale the platform to hundreds of millions of users. I wrote and maintained larger codebases running on PHP 7 (using the Symfony and Silex frameworks), Python (Data Science, monitoring applications), Golang (Microservices, tooling for operations) and - eventually - Rust (internal tooling only).Key skills:- Language-agnostic coding skills. Golang, Rustlang, Python, PHP.- Hands-on skills in Systems Design and Software Architecture.- Experience in monitoring, performance optimization.- Experienced with Docker at scale. Good understanding of the internals & challenges.- Solid Linux knowledge - tools, file systems, networking, system libraries.- Exposure to and understanding of CI/CD (Gitlab, Jenkins, Concourse).- Familiarity with Kafka, Elasticsearch, Kubernetes, Marathon, Mesos, Docker, Saltstack, Zipkin, NGINX and InfluxDB.Additionally I supported students and junior engineers with their projects. I was the supervisor for the following final papers:- Real-Time Anomaly Detection in Time Series Data Streams (Master Thesis, 2017)- Refactoring a Monolith into Microservices - An Engineering-Driven Approach (Bachelor Thesis, 2017)- Container Based Deployment of Complex Web-Applications (Bachelor Thesis, 2015)

When starting at trivago, my first goal was to improve our caching infrastructure to handle the rapidly-increasing amount of traffic. This required an in-depth analysis of our Redis/Memcached usage and optimizing Database requests. I helped introduce consistent hashing for Redis.Additionally I created and improved internal tools for trivago engineers. For example I made the Vagrant-based development environment more reliable and user-friendly.Technical advisor for Bachelor thesis about Database Migration tools.Programming Languages: PHP, Python, Ruby, CTools/Frameworks: Symfony, Vagrant, Redis, Memcached, Flyway

During my studies, a friend and me founded a company to help our clients improve their business infrastructure. We did consulting and tool development for medium-sized businesses.For example, I modernized the software and hardware infrastructure of a mid-sized medical company by creating a distributed, cloud-based, mobile-first work environment for all employees. All data can be accessed remotely. This greatly simplified the companies workflows.Programming Languages: Python, PHPTools/Frameworks: macOS (clients), Linux (server)
