About

I’m a software engineer focused on building scalable backend systems and AI-powered platforms used in production at scale. Over the last 4+ years, I’ve worked across AI, supply chain, real estate, and automation products — designing systems handling 1M+ API calls/day and AI voice platforms processing 100K+ interactions daily. My work primarily revolves around: backend architecture distributed systems performance optimization developer infrastructure AI integrations I enjoy solving engineering problems involving scale, reliability, latency, and system design — especially where product impact and infrastructure efficiency intersect. Tech stack: Node.js, React, Redis, Docker, AWS, MongoDB, WebSockets, microservices, GenAI/LLMs.
