Frontend-leaning Full-Stack Developer · Aachen, Germany

Building reliable web products, one careful component at a time.

I build fast, accessible web experiences with a strong frontend focus — currently at FEV Europe GmbH in Aachen.

02 — About

Building for the web — one careful component at a time.

I’m a junior full-stack developer based in Aachen, frontend-leaning, with a focus on clean implementation and interfaces that feel effortless to use.

Alongside my role at FEV Europe GmbH, I’m completing a B.Sc. in Computer Science at FH Aachen and building production-oriented internal tooling.

My thesis explores GenAI observability and monitoring — how to track, evaluate, and explain LLM behavior in real-world systems.

Where I’ve built things.

FEV Europe GmbH · 15 Jan 2026 – Present (contract until 14 Jun 2026)

Bachelor Thesis: GenAI Observability & Monitoring

  • Research Focus: Investigating practical approaches to track, evaluate, and explain LLM pipeline behavior in production.
  • Platform Evaluation: Assessing observability tooling such as Langfuse for tracing, latency, and feedback visibility.
  • Implementation: Building a telemetry SDK prototype and integrating it into internal workflows.
  • Data Architecture: Designing a unified telemetry model for usage, latency, and feedback signals.

Frontend Developer — Working Student (External at FEV)

  • Performance Engineering: Optimized a backend-heavy review pipeline, reducing analysis runtime from ~4.5 min to ~1 min by parallelizing independent AI/API calls.
  • Feature Ownership: Integrated chat-based exploration features for AI-generated reports and analysis outputs.
  • Cross-Tool Impact: Maintained and refined responsive UI components (complex steppers and proprietary workflows) across 10+ internal tools in total across internship + working-student periods.
  • Backend Quality: Refactored Flask components and improved API interaction performance for analysis pipelines.

FEV Europe GmbH · 14 Apr 2025 – 29 Aug 2025

Frontend Developer — Intern

  • Full-Stack Development: Built an end-to-end internal finder tool with map visualizations, advanced filtering, and skeleton loaders.
  • Latency Optimization: Reduced perceived pagination latency from ~1.5s to nearly 0ms using caching and prefetching strategies.
  • Real-Time Systems: Solved timeout issues by moving long-running checks to background Python threads and sending progress updates via WebSocket (Socket.IO).
  • Data Pipeline: Implemented dynamic backend querying with chunked/streamed responses for large filtered datasets.
  • Architectural Prototyping: Prototyped a React-based pilot to evaluate migration paths from vanilla JavaScript.
  • Team Enablement: Supported onboarding of new team members into internal tools and workflows.
