About

I am a pragmatic software engineer with an entrepreneurial mindset who understands your product and crafts with a user-first approach, delivering clean architecture using cutting-edge technology.
I love prototyping and building complex web applications from scratch. I also get excited when it comes to "replacing all the parts of a rusty airplane on the fly and safely landing with a new shiny jet."
I am looking for projects with a clear product vision where I can take responsibility and create a positive impact with my technical solutions and expertise.

Experience

GeoSphere

Austrian Weather Services

Vienna, Austria

2018 - Present

Software Engineering Consultant (freelancer)

My collaboration with ZAMG, the Austrian Weather Services (now known as GeoSphere), began in 2017. Since then, our compact yet highly effective freelance team of three software engineers has collaborated with meteorologists and scientists on several interesting and challenging software projects.

Our most exciting project so far is the European Weather Warning System. It aggregates warnings from EU member countries and provides them to data reusers such as Apple, Google, IBM, Foreca, and others. Our system is the source of all severe weather warnings displayed in native weather apps (iOS, Android), Google Search, Google Maps, AccuWeather, and many other platforms.

I have learned about the specialized and scientific domains of meteorology, GIS, online maps, and the programming language Elixir.

Built the official European Weather Warning System, Meteoalarm.org (Vue.js, Elixir)
Prototyped a weather observer data collection platform (Vue.js, Elixir, Json Schema).
Created a new Weather Warning Reporting SPA for Myanmar (Vue.js).
Built the production-ready version of Wettermelden and Trustedspotter services (React.js)
Built Ansible playbooks to automate the deployment of the Meteoalarm.org platform (Ansible, Docker)
Built sophisticated monitoring and alerting services (Grafana, Prometheus, Alertmanager)

2023 - 2024

Senior Frontend Engineer (freelancer)

Originally joined V7 to work on their AI-powered annotation platform, which was tech-wise in the sweet spot of my interests (performance-intensive rendering and drawing on canvas). However, I later had the opportunity to work on the company's newest GenAI automation tool, V7 Go, and embraced the challenge to run a marathon at a sprinter's pace, successfully bringing it to production.
