- Pegasus (production runtime agent swarm for marketing reporting): built a 7-layer architecture harness (Context, Harness, Handoff, Verification, Cost, Orchestration, Learning) on AG-UI for streaming agent events and A2UI for generative UI surfaces. Orchestrator plus sub-agents fill weekly performance templates from Meta Ads and Google Ads data with audit-trail provenance and journal-based wire assertions
- Playground (9M-user AI image generation platform): shipped new image tools, hardened payments lifecycle, contributed to core product reliability
- Alice (SMS-based AI assistant with persistent memory, voice, and tool use): led production-readiness overhaul (Cloud Run, BullMQ, pgvector), built multimodal messaging (images, voice memos, TTS), waitlist/upgrade flow, eval framework, and CI pipeline
- Cross-product infrastructure: unblocked production deploys by fixing Docker builds, Cloud Build secrets, and PGBouncer auth across all three products

Overview
Senior software engineer with 4 years shipping production DeFi systems at scale: 80K peak DAU, ~3M users, $70B+ cumulative volume across 6 chains. Sole owner of a 4-product portfolio (12 repos, 121 releases, 4,226 commits), handling frontend, API, indexer, and observability with no PM, designer, or architect required. CTO: "The kind of engineer you build a company around." Ph.D. Mathematics. Built a Claude Code agent swarm (100+ subagents) for engineering throughput and architecture enforcement.
Experience
- Building AI systems for blockchain analysis on the AI Core team, applying production DeFi engineering and agentic tooling to on-chain investigation at scale
- Primary engineer for Maverick Protocol (DeFi AMM) and 3 additional DeFi products. 80K peak DAU, ~3M users, $70B+ cumulative volume, 6 chains, 12 repos, 121 production releases, 4,226 commits
- Sole owner of V2 stack: 98% of API and 73% of frontend by code volume. CTO: "He effectively owned the entire stack."
- Built V1 API from scratch under live production traffic as app grew from 500 to 22K DAU. Ran dual-track V1-to-V2 migration without downtime while V1 served 15K+ DAU
- Built 49 Datadog dashboards (cron health, swap analytics, pricing data, RUM). Served external API consumers including CoinGecko, EtherFi, and Dune Analytics
- Hardened Ponder indexer: 4x speedup, crash loop fixes, memory leak patches. Consolidated multi-repo codebase (585 commits)
- Built 3 additional DeFi products: ve(3,3) voting/incentives platform, ERC-4626 vault protocol with cross-chain support, and an AMM frontend (sole author, 18 days)
- Built a Claude Code agent swarm (100+ subagents) for engineering throughput and architecture enforcement
