About

I'm a software engineer with 10+ years of production experience and a deep passion for building robust, scalable, and efficient systems, leveraging Go for its performance and clarity. My core strength lies in designing backend architectures that are not only high-performance but also maintainable and reliable. I thrive in end-to-end development, from early planning and architecture to hands-on implementation and optimization. Open to long-term, meaningful collaborations where I can contribute deep backend expertise and architectural insight.
