What I do best?

I build production systems across frontend, backend, blockchain, and AI — from Figma to production, serving 1M+ users.

Core capability

01. Frontend Architecture

I own frontend end-to-end — React, TypeScript, MFE, Three.js — with a focus on performance, component systems, and Core Web Vitals.

Blockchain native

02. Smart Contract Engineering

I build production Solidity systems — DEX contracts, Merkle airdrops, vesting, NFT marketplaces — across Ethereum, BNB Chain, Polygon, and zkSync.

AI-powered

03. AI & LLM Integration

I ship AI-powered features using OpenAI APIs — real-time 3D asset generation, prompt pipelines, and LLM-driven interfaces serving 1M+ users.

State & data

05. State Management & APIs

I architect complex client-side state and data layers — Redux, React Query, WebSockets — for responsive, real-time UIs.

Performance

06. Web Performance & Testing

I optimize Core Web Vitals, bundle size, and TTI. E2E testing with Synpress for Web3 wallet flows and Cypress for UI coverage.
