Jenish Vavadiya

Blockchain Developer specializing in Solana, DeFi, and MEV research, with hands-on experience building arbitrage bots, on-chain programs, and decentralized applications. Currently developing live Solana arbitrage strategies at Whistler Trading, capturing price discrepancies across DEX pools with optimized Compute Unit (CU) budgets and Jito bundle execution. Strong expertise in smart contract development using Rust and Anchor, DeFi protocol design, validator infrastructure, and real-world Web3 deployments.

SDE Intern - Whistler Trading

• Building and maintaining a live Solana arbitrage system targeting price discrepancies across All the DEX's pools including Raydium and Orca's CLMM, and AMM and Meteora DLMM-AMM and Pumpfun AMM in real-time.
• Engineered dynamic CU budget selection by profiling transaction compute requirements per route and setting precise ComputeBudget instructions to minimize fee overpay while ensuring inclusion in validator leader slots.
• Designed a priority-fee oracle that reads recent fee percentiles on-chain and auto-adjusts tip and priority-fee bids based on mempool congestion and profit margin thresholds.
• Integrated Jito block-engine bundles for atomic multi-leg execution: forward swap, backward swap, and Jito tip, eliminating sandwich exposure on profitable routes.
• Implemented profit estimation pipeline that simulates each swap leg off-chain, applies slippage models, deducts CU fees and Jito tips, and only submits bundles above a configurable net-profit floor.
• Stack: Rust, Solana, Jito SDK, Geyser Yellowstone gRPC, Pinocchio.
