ABOUT ME
Full Stack Software Developer
Full Stack Software Developer
Senior Software Engineer with 15+ years of experience working with US-based companies, specializing in React-driven frontend systems with strong Node.js backend foundations.
I focus on building product-driven, scalable web applications, translating business requirements into maintainable technical solutions with clear trade-offs.
I’ve worked end-to-end on modern web platforms, contributing to system design, performance optimization, and architectural decisions in distributed teams.
My strength lies in frontend-leaning full-stack work, bridging UI, backend, and infrastructure considerations without over-engineering.
Currently exploring AI-enabled workflows to enhance developer productivity and product capabilities.
