Build AI Products From Scratch — From Zero to Production
AI products, live class platforms, and distributed systems built from the ground up. 9+ years of turning complexity into clarity.
The Engineering Journey
For nearly a decade, I have been building systems that scale. My evolution from traditional fullstack development to AI engineering represents a deliberate pivot toward the future of software. I focus on production-grade Retrieval-Augmented Generation (RAG) pipelines, LLM integrations, and ensuring the architecture underneath is unshakeable. It is not just about writing code — it is about engineering clarity from complexity.
