Full-stack engineer building high-performance Web3 applications, AI-powered systems, and scalable products that reach thousands of users globally.
Who I Am
I'm a self-driven software engineer with over 3 years of experience building high-performance applications across full-stack, Web3, and AI domains.
As Frontend Lead at Funavry Technologies, I architect and ship large-scale decentralized applications for the ChainGPT ecosystem — from multi-chain NFT platforms to DeFi launchpads — serving thousands of users globally.
Beyond blockchain, I'm deeply invested in AI engineering — building RAG systems, agentic workflows with LangGraph, and tool-calling pipelines that bridge intelligent models with real-world data.
I thrive at the intersection of complex architecture and clean user experience — turning ambitious ideas into fast, scalable, and delightful products.
