I'm a software engineer in New York. I build agent infrastructure, protocol systems, and products where the backend has to hold up under real use.
Right now I'm at Towns Labs / Here Not There, working on Slashtalk: a desktop app that shows what a team is shipping by pulling together Claude/Codex sessions, PRs, file-conflict signals, and MCP-accessible project context.
Before that I worked on Towns Protocol, an open-source decentralized E2EE messaging protocol built with Go, TypeScript, and Solidity. Before Towns: DeFi software at Aave, and real-time interactive web systems at Active Theory.
- Slashtalk — desktop app + backend for live coding sessions, PR activity, conflict warnings, and MCP-based team context.
- Towns Protocol — decentralized E2EE messaging protocol with programmable on-chain spaces and cross-chain entitlements.
- harness-mcp — TypeScript starter kit for MCP servers with typed tools, stdio/HTTP transports, model-facing errors, and model-based tests.
- pi-goals — Pi extension for persistent goals, queues, budgets, and safer long-running agent sessions.
- software-factory — Bun/TypeScript CLI for turning an idea into plans, prototypes, reviews, QA passes, and retros with isolated agent work.
- wiki — LLM-maintained markdown wiki that ingests sources, rewrites linked pages, and keeps durable context useful across sessions.
- local-autoresearch — local-first research CLI with a cheap local loop and occasional frontier-model review.
- solveit — Claude Code plugin for small verified checkpoints, narrow diffs, and human-in-the-loop coding discipline.
- Agents: MCP, skills, memory, workflows, evals, harness design.
- Product/backend systems: TypeScript, Node/Bun, Go, APIs, WebSockets, Postgres, Redis.
- Protocols: Solidity, Foundry, EVM, tokenomics, cross-chain validation, indexing, security.
- Product craft: making complicated systems feel simple enough that people actually use them.
