What I'm looking for

I am looking for opportunities that allow me to leverage my backend development skills while working in a collaborative environment that values innovation and continuous learning.

I am a dedicated Golang Developer with a strong focus on building scalable, high-performance systems. My experience includes working with Germany's largest retail company, where I contributed to the delivery team by leveraging my expertise in Golang, PostgreSQL, and Kafka. I have successfully developed a high-load Competitor Price Aggregation system that handles over 100K products, showcasing my ability to manage complex data flows and optimize performance.

My passion for clean architecture and modern DevOps practices drives me to continuously improve my skills. I have built ETL pipelines and parsers that stream structured data to machine learning teams for price analysis and experimentation. Additionally, I have enhanced delivery admin panels with new features and improved job execution through SQL optimization. I thrive in dynamic environments where I can apply my knowledge of distributed systems, data pipelines, and performance optimization.
