OpenMeter (YC W23) eliminates the heavy lifting of real-time and accurate metering for AI, API, and DevOps applications. We enable billing, product, and analytics use cases for the next generation of data-intensive applications. Usage-based pricing with per-second granularity, per API, or token usage is streamlined with OpenMeter.

Part of the internal CORE team we are specialising in DevOps tasks for setting up and managing mission critical microservices of Trace, our Node.js monitoring and debugging solution, running with containerised technologies like Docker and Kubernetes. I worked on the on-premises version of Trace. My main responsibility was to design and implement the Terraform script, which sets up the infrastructure on AWS.

I have been working on Trace, our Node.js monitoring and debugging solution, including all parts of the development stack: designing, implementing and operating microservices, creating frontend user interfaces, developing internal tools.

I was working for two companies based in the United States. One of them included a full rework and further development of an existing Node.js application. On the other project we took over an open- source Angular application and developed new features. Both times I was in direct communication with the clients.

I wrote my diploma thesis at RisingStack on "Challanges and solutions in data retrieval for modern applications". Part of the research I authored an open source project for GraphQL called Graffiti. It has over 1000 stars on Github.

My project was to optimize the communication between the backend and the frontend for Buildbot, a continuous integration framework. This project included the re-implementation of the client side AngularJS data service as a standalone module and the elaboration of various data flow optimizations.

My project was to reimplement the Console and the Waterfall views for the new version (nine) of Buildbot, a continuous integration framework. The client side of the web UI is written in AngularJS. I've used the following technologies: AngularJS, D3.js, CoffeeScript, Jade, Less, Grunt.
