Fynn Fischbach
Full Stack Developer
6+ years of experience in agile software development and production-grade AI engineering.
I build reliable applications across the entire stack — from React, Next.js, and Angular frontends to Java/Spring Boot and Python backends, plus cloud infrastructure with Azure, AWS, and Terraform.
Currently working on platforms in the automotive sector, building agentic systems with MCP, A2A, and LangGraph, and contributing to open source projects.
I enjoy working directly with stakeholders to turn complex requirements into clear technical concepts and maintainable code.
