// 01. About

Engineer with end-to-end ownership

I'm a senior engineer who works at the intersection of smart contracts and production backend systems. Most of my recent work has been about owning a feature all the way through — from Solidity design and Foundry tests, through audit, to the API and indexer layer that consumes it.

I've shipped on Base, Ethereum, BSC, Polygon, Arbitrum, Optimism, Solana, and Aptos/Move. My contract suites have passed third-party audits including Hacken (10/10 security) and AstraSec. On the backend, I work daily with TypeScript, Node.js (Hono / Express), PostgreSQL, ClickHouse, Kafka, Redis, and AWS.

Outside of work I spend a lot of time on on-chain research — tracing transaction flows through smart contracts, reverse-engineering protocols, and running a small arbitrage system on BSC and ETH. It keeps my engineering instincts sharp and my security perspective grounded in how attacks actually happen.

Things I've built for fun

🐱 Catapult
Live · Sepolia
An EVM cat-coin launchpad in the style of Pump.fun. Users launch a custom ERC-20, trade it on a bonding curve, and once the curve graduates (hits target raise) liquidity migrates to Uniswap V2 and LP tokens are burned permanently. Multi-chain by chainId. Comes with a King-of-the-Hill hero, wallet-only comments, live-updating token feed, editable profiles, and GeckoTerminal chart embeds for graduated pools.

🎮 LOL Fantasy Arena
Testnet · Base
A just-for-fun fantasy League of Legends esports game. Pro players are ERC-20 tokens trading on bonding curves quoted in a main LOL token. Users field a lineup by locking an eligibility escrow, distribute a 100-point conviction budget across their picks, and win a LOL prize pool based on pros' real match performance (kills, assists, wins, pentakills, baron steals). Skill decides the pot, not wallet size. Every player token is simultaneously a speculative asset and a fantasy game piece — that dual use is the core of the design.
