I keep the world's reference plant-biology database running by day — and ship AI products, games, and agent tooling at night.

Senior Software Engineer @ Phoenix Bioinformatics · SF Bay Area

Now — July 2026

  • Shipped Counterpoint for OpenAI Build Week — paste a lesson passage, an agent compiles it into a playable 2.5D mission. Playable now.
  • Running DesignForYou and WriteForYou, my two production AI studios.
  • Benchmarking scene-placement geometry so game characters stand believably in generated worlds.

Products

Everything below is live, with real users and real billing, shipped from Molty — my agent-powered studio.

  • DesignForYou — AI design-template generator, listed on the official MCP Registry.
  • WriteForYou — an MCP-first AI fiction studio; ~100 tools behind a planner→writer pipeline.
  • JobsForYou — resume-aware job alerts with a browser autofill agent; web, iOS, and MCP.
  • VN Creator — generate a playable visual novel: story, sprites, scenes.

Playground

  • Counterpoint — a mission compiler for teachers: lesson passage in, playable history game out.
  • 3D Car Assembler — an R3F playground that grew a car configurator, a stealth heist game, and a physics demolition yard.
  • TORN City — a GTA-style text crime RPG, built in three days.
  • Problem Recall — a LeetCode pattern trainer with hand-animated algorithm visualizations.

Open source

  • three-box3d — three.js / React Three Fiber bindings for the box3d physics engine. (npm)
  • mcp-core-auth — shared auth, billing, and logging for MCP servers; runs under three of my production servers. (PyPI)
  • browser-harness — a ~600-line CDP harness that lets an AI agent drive a real browser and extend its own tools mid-task.

Day job

Since 2018 I've been at Phoenix Bioinformatics, the nonprofit that runs TAIR — the reference genomics database for plant biology, used by researchers worldwide. I led TAIR's migration from a legacy monolith to modern cloud architecture, and built PhyloGenes, an NSF-funded gene-function tool used by 17,000+ researchers. Co-author of “The Arabidopsis Information Resource in 2024” (Genetics). BOSC 2024 organizing committee.

Molty

Most of what I ship comes out of Molty — my agent-powered studio: a stack of AI agents that build, test, record, and market alongside me. It has its own page → molty.swapp1990.org
