As a Principal Engineer, I architect and deliver partner-facing platforms — from secure API ecosystems to intelligent AI-powered chatbots.

My expertise spans Node.js, Python, .NET/C#, React, AWS, Azure, DevOps, and conversational AI using LLMs, Retrieval-Augmented Generation (RAG), and the Model Context Protocol (MCP).

I build platforms that bridge business goals and engineering execution, integrating serverless APIs, custom knowledge bases, and microservices architectures at enterprise scale.

With over 14 years of hands-on engineering experience, I've led initiatives at a Fortune 500 software company and a global gaming leader, delivering solutions that accelerate partner onboarding and adoption.

I thrive on creating clean, secure, and resilient systems — whether it's backend performance, frontend usability, cloud infrastructure, or AI automation pipelines. I enjoy mentoring teams and solving complex integration and scalability challenges.

Delivering results through expertise, collaboration, and a commitment to excellence.
