AutoDroid
An Android app builder that runs entirely on the phone, for people who don't code. Apps are data executed by one runtime inside the app.
I build multi-agent harnesses that do real work and show their sources.
I'm the Founding AI Engineer at BuildMarshal, where I build Marshal, a set of agents behind one orchestrator that read a team's email, meetings and tens of thousands of documents, answer with page-level citations, read CAD/BIM drawings and LiDAR scans, and act only after a person approves.

Harness engineering
Agents that read everything, cite everything, and wait for a yes
A harness is everything around the model, from orchestration and retrieval to memory, tools, approvals and cost control. That layer is where a domain product beats a generic chatbot.

Marshal
A multi-agent harness for project managers in construction and prefab. Many action agents and read/write services sit behind one orchestrator, on web, iPhone and Mac. Nothing changes until a person approves.
buildmarshal.aiAmbient processing
Email, documents and meeting recordings read in the background, matched to projects, classified, with respond-by dates.
Cited RAG
Vector, keyword and knowledge-graph search. Each citation opens the exact PDF page or drawing. No citation, no claim.
Approval cards
Tasks, reply drafts and schedule changes arrive as cards with iPhone push. Writes never run twice.
Agent memory
A nightly consolidation cycle refreshes memory for every project, person and vendor.
CAD/BIM, LiDAR, photos
DXF, IFC and STEP read as rooms and prefab lists, plus LiDAR room scans and GPS-matched site photos.
Cost engineering
Small-model skip gates, deduplication, batch APIs and capped structured outputs.
