01 / About
Self-taught, shipping on-chain.
I build the full stack — from Solidity and Anchor contracts to React front-ends — with a deep interest in how the EVM & SVM actually work under the hood.

Currently pursuing a Computer Science degree at RGUKT Nuzvid. I started building on Ethereum in 2022 and on Solana a year later, with a working knowledge of Merkle trees, Solana Pay & Blinks, and applied cryptography.
I move comfortably across NFTs and DeFi protocols, and I'm always adopting new tools that make a protocol safer and a build faster.
