Design-minded engineer. I care about performance, polish, and the small decisions that separate good software from great. I've been building across crypto and fintech, exchange platforms, trading terminals, and tools that handle real money at scale.

Milkshake
An embeddable crypto-to-crypto cross-chain swap widget built with React. Allows for custom themes, configurable networks / assets, and supports multi-network wallet connections.

Merkle Mines
A provably-fair Bitcoin mines game with a full double-entry ledger, Web3 auth, and Lightning Network support. Every round is cryptographically verifiable.

Aeven
An isometric pixel-art MMORPG built entirely in Rust. Features real-time multiplayer combat, skill progression, Lua-scripted quests, and cross-platform support via native and WebAssembly builds.

Swappage
A cross-chain swap platform built with Next.js, Radix UI, Redux, and Supabase. Supports all EVM-compatible networks and Solana.
Frontend Engineer
Led a full platform rewrite from a legacy Create React App codebase to a modern stack with TanStack Start and Zedux for state management, optimizing for low latency and high performance across an all-in-one crypto trading terminal.
Frontend Engineer
Fixed bugs, shipped new features, and improved page load speeds and SEO observability. Architected system protection measures to mitigate DDoS attacks and significantly cut infrastructure costs.
Support Lead → Project Manager
Grew from front-line support into managing the team, then into project management over three years. As PM, shipped key revenue projects for exchange and fiat services. Led partner policy overhauls that significantly reduced transaction fees.
