About
I’m a mobile application developer who enjoys building sleek, high-performance apps with a strong focus on user experience. I specialize in Flutter-based mobile development and love turning ideas into reliable, end-to-end solutions that feel smooth to use.
On the backend side, I build robust systems using Spring Boot and use Python for data-driven insights. I’ve worked across fintech and real-world consumer apps—integrating APIs, improving app functionality, and shipping features that support secure, dependable financial and messaging experiences.
