I design and operate complex, low-latency systems — trading infrastructure, distributed backends, and smart-contract security tooling. From real-time Go execution engines to fuzzing tools used across the audit community.
// 01 — about
I architect and operate complex, low-latency systems — from real-time ingestion to live execution.
Senior software engineer with 5+ years building production systems across high-performance backends, real-time data pipelines, and distributed infrastructure. Today I run my own quantitative trading firm as sole engineer — architecting low-latency Go execution engines and multi-service backends, live on Hyperliquid & Binance.
Before going solo I led engineering at blockchain-security firm Recon and drove product as a technical owner at Code4rena, building tooling now relied on by hundreds of auditors.
Prior to engineering, a decade leading international B2B sales teams of 10+ with $50M+ budgets — where I learned to ship outcomes, not just code.

Things I've built.
Hyperblitz
End-to-end autonomous quant trading system. A custom algorithm trained on limit-order-book data executes live on Hyperliquid — no human in the loop.
PumpSonar
Production Telegram bot letting users create wallets and trade any Solana token. Air-gapped key storage via hash-fragment distribution, Jupiter DEX + Helius RPC for real-time execution.
Arbitrage Detection Bot
Real-time order-book aggregator identifying cross-exchange arbitrage opportunities across multiple venues with sub-second latency.
