About

I’m Mirko Miličević, a Senior Software Engineer focused on building scalable, reliable systems and data-driven applications. I design backend architectures, optimize data flows, and deliver production-grade services with high performance and stability.

I specialize in Python, Go, Ruby on Rails, and Node.js, and have hands-on experience with RESTful and GraphQL APIs. I work with relational and NoSQL databases, implement caching, asynchronous processing, and efficient data handling, and design distributed systems for real-world reliability. I enjoy working across the stack when needed—frontend frameworks like React.js, Vue.js, and Next.js are within reach, and I also bring a grounding in C/C++ and exposure to ML/NLP concepts to support pragmatic problem solving. I’m passionate about clean, maintainable code and collaborating with cross-functional teams to ship impactful features quickly.
