Sean Traynor
AI Systems Architect
AI Systems Engineer. 18 months building agentic systems — from Cursor at MakenaAI (enterprise PropTech) through a custom multi-agent OS framework — culminating in 18 days on Claude Max: 1,005 tickets merged (1,458 processed), 52 agents deployed across 9 repos. Tufts CS. 2019 NCAA National Champion.
Current focus
- 01 Agentic orchestration at OS scale — 7-domain multi-agent OS: 52 agents, ticket-executor FSM, pre-merge-gate hooks, verifier/executor trust boundaries, and daily wiki distillation across 9 interconnected repos. 1,005 tickets merged (1,458 processed) in 18 days on Claude Max.
- 02 Production iOS engineering — Swift, SwiftUI, ARKit. Columbia University research platform (NIH grant, published in European Journal of Neuroscience), MakenaAI enterprise mobile (2,000+ subscribers onboarded in week one).
- 03 Applied AI for high-stakes domains — production pipelines for education, music, trading, and enterprise property tech — where correctness and auditability matter as much as velocity.
- 04 Targeting senior AI roles — open to AI Engineering, AI Operations, and Solutions Architecture positions at frontier-AI companies (Anthropic, W&B, Scale AI, Harvey AI, Cognition AI).
Selected work
Master OS
7-domain agentic operating system: Phase 6 orchestration, ticket executor FSM, pre-merge-gate hooks, and daily wiki distillation. 241 tests, A 19/19.
Read case study →Agentic Orchestration Patterns
Five design patterns from building a production multi-agent OS: hooks as trust boundaries, agent contracts, hybrid orchestration, and distillation as compounding memory.

Swift engineering across Columbia University research (NIH grant, published in European Journal of Neuroscience, 4,000+ patients) and MakenaAI enterprise property tech (ARKit, 2,000+ subscription clients).
View iOS work →Sandbox
AI-native content and curriculum engine (Sandbox Creative LLC). Three delivery layers: University ($49/mo), Labs (custom AI systems for businesses), and a parent brand co-led with Daniel Fitzgibbons. Flagship: SandboxOS — 9 agents, 72-lesson curriculum.
View project →VioletStudios
Bloom AI mixing and mastering platform, Production Services for artists and labels, Petals Plug-in Suite (C++ DSP), and Sample + Blog GTM. Bloom POC in one weekend. Production Services active; Bloom V2 in development.
View project →Blockwise Intelligence
Autonomous AI-native quantitative finance research lab. Co-built with Finn Westerink. Fresh-start brand as of May 2026 — designing research infrastructure for agentic operators, not legacy quant teams.
