snipe-dev | Backend & Web3 Engineer

About

Focused on EVM infrastructure, real-time on-chain systems, DeFi execution and wallet-connected dApps.

I build:

Mempool monitoring & transaction decoding systems
Whale alerts and real-time on-chain notifications
MEV-aware trading & execution bots
Wallet-connected frontend + backend infrastructure (dApps, NFT platforms)

Currently open to Remote Web3 Fullstack / Backend / DeFi Infrastructure roles (full-time).
