Colorado → San Francisco, Jan 2027

I build backends that have to be right under load: queue-driven AI pipelines, Solana data ingestion and pricing, game economies. Most recently I led a team of six at Step Finance.

    Ingestooor

    High-throughput Solana transaction ingestion, typed end to end.

    Solana transactions arrive over RabbitMQ. Parsers for Jupiter, Raydium, Orca, Kamino and more filter by program ID and turn matches into typed records called Dooots, batched into ClickHouse and Postgres on per-table flush timers.

    DojoPacks

    A Pokémon TCG collecting game that lives in Discord.

    Open a free booster every 10 minutes from a rotation of 125 sets, trade, grade cards into slabs and spend DojoTokens. The owner dashboard flags any rarity whose pull rate drifts more than 3σ from its odds.

    ArchipelaPal

    A bot that plays its own world in an Archipelago multiworld.

    In a co-op randomizer where your items hide in other players' games, ArchipelaPal plays a world of its own: it unlocks regions with keys, checks locations on a timer, chases hints, and says when it's stuck waiting on others.

    VATMissions

    Career-style missions for pilots flying live on VATSIM.

    Air traffic facility admins author missions between real airports. A Go worker polls the VATSIM feed every 30 seconds, walks each pilot through a forward-only state machine stored in Redis, and writes the reward to Postgres on landing.

    Veritas

    Graph-based BFS pricing across any kind of market.

    Token mints are nodes and pool liquidity relations are edges. From oracle-priced seeds, a BFS derives every other price as a liquidity-weighted average of its neighbours, skips high-impact relations, and emits when a price moves. It consumes Ingestooor's Dooots.
