What I'm looking for

I’m looking for a role where I can build scalable, high-performance web apps with React, deliver responsive and accessible UX, and integrate APIs for data-rich experiences. I want a collaborative team that values clear communication, quality, and continuous improvement.

I’m a Front-end Developer with 5+ years of experience building scalable, high-performance web applications across the full development life cycle. I focus on responsive, accessible, user-centric interfaces—and I enjoy connecting the UI to real data through APIs.

In my projects, I’ve built interactive dashboards and WebGIS experiences that feel fast and intuitive. I integrated aviation and weather data via external APIs, created map-based visualizations, and improved user experience with thoughtful UI/UX and accurate time conversions.

My background also blends frontend engineering with hands-on data and backend skills. I’ve delivered REST/GraphQL/WebSocket-driven features, developed CI/CD-enabled ETL pipelines for live Germany datasets, and worked with PostgreSQL/PostGIS and MongoDB Atlas for reliable storage and geospatial querying.

I’m known for creative problem-solving, clear communication, and a collaborative approach to high-quality delivery. Whether optimizing performance, improving accessibility, or refining data workflows, I’m motivated by building solutions that are both technically solid and genuinely useful.
