Agentic Engineer for practical web systems and automation.

I am a full-stack web developer building local-first tools, AI workflow infrastructure, media pipelines, and client-side automation with clear evidence, safety gates, and resumable delivery.

AI Workflow Tooling

Mark Project Builder

Codex-first project operating system for turning ideas and repos into plans, tickets, sprints, review packets, and approval-gated release work.

  • Local artifacts track intake, planning, tickets, sprints, status, gates, and handoff packets.
  • ClickUp is treated as a visibility mirror rather than the source of truth.

Media Automation

Twitch Content Grabber

Pipeline for turning selected Minecraft Twitch VODs into reviewed YouTube Shorts with quality gates before publishing.

  • VOD-centered review flow keeps quality checks before publication.
  • Worker pipeline covers download, transcription, scoring, rendering, and upload preparation.

Local Desktop Automation

PhotoDrain and PhotoVault FreeUp

Local desktop assistants for Google Photos backup and cleanup with explicit confirmation before destructive actions.

  • Manual Google login avoids password storage and security bypass behavior.
  • Local validation and dedupe reporting happen before cleanup.
