Hi, I'm Niklas

Software Engineer · Java & Spring Boot · TypeScript & React · Python agent systems · Cloud-native
LinkedIn · Dev.to

I design, ship, and operate end-to-end software, from architecture and API contracts to deployment and observability. My core stack is Java/Spring Boot and TypeScript/React, and I am extending that foundation with typed Python services that turn natural-language and voice requests into testable application actions.

Projects

  • IMDb Clone (current focus) - A live Spring Boot and React movie discovery platform with PostgreSQL, OpenSearch hybrid search, and semantic recommendations. I operate it on a self-hosted k3s cluster using Argo CD and Grafana. I am currently adding a Python agent service that translates voice commands into typed application actions, allowing the React client to navigate and render the appropriate UI.
  • GitHub Trending API - A FastAPI service with typed OpenAPI responses, caching, operational endpoints, CI and coverage, and automated Docker releases.
  • JobLens - An LLM tool built for my own Swiss job search that turns job-posting matches into structured, explainable relevance scores.

Open-source focus: Reliable Python agent services with typed tools, structured outputs, evaluation, observability, and explicit control over side effects.
