About

I’m a Software Engineer at UBS focused on building scalable systems and high-performance backend applications. In my current role, I work on designing and developing backend services, with a strong focus on system design, performance, and maintainability. I enjoy breaking down complex problems and building solutions that are efficient, reliable, and easy to scale. My primary interests lie in distributed systems and backend engineering, where I focus on designing systems that handle real-world complexity while maintaining performance and reliability. Outside of work, I actively engage in competitive programming (Codeforces Specialist, LeetCode Knight), which sharpens my problem-solving skills and strengthens my understanding of algorithms and data structures. I also build projects centered around real-world system design, including applications in finance and data-intensive systems, with an emphasis on clean architecture and practical engineering. I’m looking to contribute to teams building large-scale, high-impact systems, particularly in domains like financial technology and distributed platforms.
