About Me

As a Software Engineer, I transform complex challenges into high-performance web applications and resilient cloud architectures. My expertise spans modern full-stack development with React and Node.js, complemented by a deep specialization in Python for Machine Learning and advanced AI integrations using LangChain & LangGraph.

I thrive on building scalable, efficient, and user-centric solutions that drive tangible business value.
