Rust Engineer — Miami

ZION
MELSON

Markets leave gaps. I build systems that close them.

Currently engineering Quidity, a DeFi quant desk for Solana. Before that, I turned a Discord server into a hiring desk for startups and FAANG-caliber talent.

// About

I've spent my career closing the distance between people who have what the other side needs. First it was startups and talent — Learnmutiny turned a Discord server into a hiring desk, no recruiters, no cold DMs, just a vetted room where the right people found each other. It grew past 8,000 members and had its own Product Hunt moment as "Tinder for startups."

Now it's value. Quidity is the quant desk that pulls liquidity, yield, and arbitrage back under one roof across Solana DeFi. I write the Rust that finds the gap between Kamino, Orca, Meteora, Raydium, and half a dozen other venues — and closes it before anyone else does.

Quidity

Engineer

A DeFi quant desk from your MacBook — built because value is too scattered across Solana DeFi, and someone needed to build the room where it all comes back together. Invite-only, live on mainnet.

  • Built the core low-latency arbitrage engine in Rust 🦞
  • Live integrations with Kamino, Orca Whirlpools, Meteora DLMM, Raydium, Fusion AMM, and BYREAL
  • Designed an LP strategy covering fee capture, funding-rate harvesting, and trend-following perpetual futures

Learnmutiny

Founder

A hiring desk built natively on Discord. "mu" let approved startups, VCs, and FAANG-caliber engineers talk directly, with a weekly-reviewed approval gate instead of a recruiter pipeline.

  • Grew the server to 8,000+ members from zero
  • Designed tiered access across candidates, startups, and hiring companies
  • Shipped the web app and companion Chrome extension behind the application flow
  • Launched on Product Hunt — "it's like Tinder for startups"
