Jenish Vavadiya
Defi Engineer

I'm a software engineer focused on blockchain infrastructure, quantitative trading systems, and Defi.

Built a solana arbitrage infrastructure, researching mev, and studying how execution, validator behavior, and market microstructure interact at scale.

I enjoy understanding how things work under the hood—from transaction scheduling and compute optimization to auction mechanisms and exchange design. most weekends are spent reading protocol code, experimenting with trading strategies, or building tools in rust.
