About

I am a Full-Stack Software Engineer with hands-on experience building production-grade mobile applications, scalable backend systems, and AI-powered features.

Currently working as a Software Engineer, I build high-performance React Native applications, design secure and scalable backend APIs, and integrate AI systems using LLM-based workflows.

I enjoy owning features end to end — from mobile UI and system architecture to backend logic and intelligent AI pipelines — with a strong focus on performance, maintainability, and real-world impact.
