TECHNICAL CO-FOUNDER

Ten years of taking products
from idea to production.

I design, architect, and ship software end to end: AI systems, real-time multiplayer infrastructure, consumer platforms, and developer tools. Fifteen products over the past decade, each owned across the full lifecycle, from product strategy and system design through engineering, deployment, and iteration.

Currently building Aftlog, an open-source flight recorder for AI coding agents.

SELECTED WORK · 2018 TO PRESENT

Products

Aftlog repository
2026 Code ↗

Aftlog

A local-first flight recorder for AI coding agents. Records every shell command and file modification an agent makes, generates session reports in Markdown, JSON, and HTML, and provides a two-step revert workflow with backups. Git-aware diffing separates agent changes from pre-existing work; heuristics flag secret exposure and dependency risks.

Everby

A native macOS accountability companion, chat-first and notification-driven. Layered memory architecture with transcripts, rolling summaries, and durable facts; local tool calling for reminders and commitments; voice dictation and inline notification replies.

Scrute Labs website
2025 Live ↗

Scrute

AI document intelligence for commercial real estate compliance. TitleCheck AI reconciles title commitments against ALTA surveys with page-level evidence reports; PermitCheck AI reviews architectural plan sets against NYC building, zoning, and fire codes with exact code citations. A multimodal pipeline combining legal text extraction, survey vision, and spatial analysis.

Commentrix website

Commentrix

Real-time AI sports commentary. A vision pipeline reads live game footage, a commentary engine generates play-by-play, and neural text-to-speech delivers it in multiple languages. Designed for platforms running many simultaneous games.

Python · FastAPI · Gemini · ElevenLabs

Aiditor website

Aiditor

A chat-based editing agent for video, audio, and images. Natural language instructions compile to FFmpeg operations and sandboxed Python execution, collapsing a multi-application editing workflow into a single conversational interface.

TOOLING AND INFRASTRUCTURE

TECHNICAL RANGE

Capabilities

AI systems

LLM pipelines, multimodal vision, and voice in production: agent architectures, tool calling, document intelligence, real-time speech. Claude, Gemini, and OpenAI APIs; ElevenLabs synthesis; STT/TTS systems.

Real-time infrastructure

WebSocket architectures, Redis-backed state, multiplayer game loops, and live leaderboards, operated at tens of thousands of concurrent players.

Native and systems

Rust CLIs and daemons with filesystem-level instrumentation; native macOS applications in Swift 6 and AppKit; game engineering in Unity and C#.

Web platforms

Next.js, Node.js, Python, and Flask applications on AWS and Cloudflare: serverless pipelines, email infrastructure, entitlement systems, MySQL, DynamoDB, Redis.

CURRENTLY

Building, and open to the right partnership

IN DEVELOPMENT

Aftlog, in the open

AI coding agents change code and run commands at machine speed; teams need an audit trail. Aftlog records every command and file change locally, produces reviewable session reports, and makes any change revertible. Rust, MIT licensed.

CO-FOUNDER / FOUNDING CTO

A hard problem worth solving

I partner best with operators and domain experts who know an industry deeply. If a problem can be solved with software, I can architect and build the solution, from first prototype to production system.
