Co-led development of Orb, Helius’s Solana block explorer, driving the project from initial architecture through to a successful public launch. Built trading-oriented features including token swap, staking components, and market data tables, integrating multiple external and internal APIs with JWT authentication, Cloudflare Turnstile verification, and analytics tracking. Contributed to the Helius monorepo - Orb backend API routes (Node.js), implementing secure data-fetching patterns, caching strategies, and rate limiting to handle high-traffic Solana RPC and archival queries at scale. Collaborated daily with designers, core infrastructure engineers, and public beta testing groups in an async-first environment to ship iteratively and respond to user feedback. Represented Helius at blockchain conferences and events, delivering technical talks on Solana infrastructure and developer tooling.

Built the Arcana Markets web app, a full-featured DeFi dashboard with live orderbook visualization, interactive charts, token swap interface, and real-time market data for Solana DEXs including OpenBook v2 and Phoenix; deployed and hosted on Vercel. Developed and shipped an automated market-making trading bot (Java, Spring) with a local web GUI, Docker support, and 12 production releases - deployed on VPS for persistent uptime across Solana DEX pairs. Contributed to an on-chain market-making vault program written in Rust using the Anchor framework, deployed to Solana devnet for secure, decentralized token storage and automated liquidity provision.

Contributed to the OpenBook v2 monorepo (Rust program + TypeScript client), improving developer tooling for Solana’s leading community-driven central limit order book DEX. Designed and built openbook.ag (Next.js, TypeScript), the official community landing page for the OpenBook DEX, published under the openbook-dex GitHub organization.

Contributed to the SolApe DEX frontend, building new components and pages, updating designs, and optimizing the existing codebase for the community-bootstrapped exchange. Experimented with on-chain Solana program development, building a coinflip game and a VRF-powered raffle system (Rust, Anchor, TypeScript) using Switchboard oracles for provably fair randomness – early hands-on experience that laid the foundation for deeper blockchain engineering work.
