🚀 Principal Full-Stack & Agentic AI Systems Architect • US Remote

Shipping Production Multi-Agent Systems at 10x Velocity with Google Antigravity CLI

I am a hands-on principal full-stack and platform architect who designs, builds, and operates real production software ecosystems. Rather than relying on slow chat-only autocomplete boxes, I pair-program daily with Google Antigravity CLI (agy), Vertex AI (Gemini / Imagen / Veo), Python (FastAPI / WhisperX / FFmpeg), and Node.js/JavaScript using spec-driven rules, custom agent skills, and automated verification loops.

6 Real Systems Running in Production

Each card starts with a plain-English summary followed by the technical architecture. Use the quick-jump bar below to hop directly to any system or expand/collapse details.

FLAGSHIP INFRASTRUCTURE Google Antigravity CLI (agy) Python + Node.js + SQLite Distributed Mutex & Rate-Limit Control

1. Cross-Service Google Antigravity CLI Orchestrator & 3-Lane Async Queue Engine

Unified agent orchestration backbone coordinating autonomous agy CLI runs, Vertex AI calls, and GPU/CPU media workers across multiple Node.js and Python production services without OAuth token collisions or rate-limit lockouts.

▾ Expanded

💡 In Plain English: Running multiple AI agents across different servers at the same time usually causes login tokens to overwrite each other or triggers rate-limit bans. I built a central traffic controller with three dedicated express lanes (AI Reasoning, Image Generation, and Video Rendering) so users never wait on a slow video render just to run an AI prompt.

🎯 Architectural Challenge & Solution

Cross-Process OAuth & Cooldown Safety: Engineered a file-backed cross-service mutex (GlobalAgyLock) with PID liveness verification, stale-lock recovery, and a strict minimum 10s-15s inter-command cooldown.
3 Independent Parallel Queue Lanes: Separated workloads into 🤖 AGY (CLI agent reasoning/choreography), 🚀 Vertex (high-speed Imagen/Veo API generation), and 🎬 Video (FFmpeg rendering).
Access-Scoped Multi-Tenant Visibility: Real-time per-lane queue telemetry (lane_position, ahead_in_lane) scoped by user role and project collaboration permissions.

🛠️ Key Engineering Highlights

Custom .agents/rules & Skills Architecture: Codified strict architectural invariants, local-to-VPS rsync deployment hooks, and subagent delegation rules so agents execute complex refactors deterministically.
Remote Web CLI Console: Built an owner-only, TOTP/MFA-protected web terminal on Creative Breath that streams live agy CLI execution and tracks rolling 5-hour sprint and weekly quota usage.
Hot-Endpoint Zero-I/O Caching: Eliminated cloud-mount filesystem scans (rclone) on high-frequency polling routes using an in-memory + SQLite metadata cache.

AI VIDEO & CHOREOGRAPHY Python / FastAPI / SQLite WhisperX + Vertex AI + FFmpeg

2. BMDS - Beat Match AI Director Studio

End-to-end AI music video production studio that aligns audio stems to word-level timestamps, choreographs visual storylines across 60+ slides using an overlapping AI Director window, and renders beat-accurate 16:9 and 9:16 videos.

▾ Expanded

💡 In Plain English: When AI generates 60+ images for a music video in separate batches, characters and scenes often change outfits or settings abruptly between batches. I solved this by overlapping every batch by one frame (1-5, 5-9, 9-13...) so the last image of one batch visually anchors the first image of the next, keeping the story seamless from start to finish.

🎯 Overlapping 1-Image Continuity Director

Sliding Window Context Engineering (1-5, 5-9, 9-13...): Engineered execute_auto_choreograph_logic with a strict 1-image overlap (step = batch_size - 1) so the final frame of batch N anchors the visual state of batch N+1.
Clean-Slate Regeneration with Atomic .bak Rollback: When regenerating an existing slide, the old asset is moved to .bak and excluded from ImagePaths so the multimodal model generates a fresh composition rather than copying the old slide, while automatically restoring .bak if retries fail.

🛠️ Performance & Media Pipeline

WhisperX Forced Alignment: Sub-second word and lyric boundary detection driving automated beat-matched slide transitions and multi-language .srt subtitle tracks.
Immutable Browser Disk Caching: Per-slide image_version timestamps and _collab_revision state paired with Cache-Control: private, max-age=31536000, immutable so unchanged slides load in 0ms from local disk cache.

MULTI-PLATFORM STUDIO EXTENSION YouTube • TikTok • Suno • DistroKid Zero-Disk Video Streamer & 13-Lang .srt Bridge

3. Creative Breath Companion Extension & DistroKid Mastering Suite

Custom Manifest V3 Chrome Extension and mastering pipeline that streams rendered videos directly from BMDS into YouTube Studio and TikTok Studio without disk downloads, automates multi-language .srt subtitle management at zero API quota cost, extracts multitrack stems/MIDI from Suno, and packages DistroKid-ready mastered albums.

▾ Expanded

💡 In Plain English: Publishing a song and music video across Suno, DistroKid, YouTube, and TikTok normally takes hours of downloading giant files, renaming tracks, uploading videos, and pasting translated subtitles for 13 languages. I built a custom Chrome extension and mastering suite that streams the finished video directly into YouTube and TikTok in memory, fills out every title/mention/thumbnail, uploads all multi-language subtitles in one click without touching YouTube API quotas, and exports a mastered DistroKid album ZIP.

🎯 Multi-Platform Video Upload & Automated Subtitles

Zero-Disk BMDS Video Streamer (YouTube & TikTok Studio): Streams rendered 16:9 and 9:16 .mp4 videos and custom cover.png thumbnails directly from BMDS into YouTube Studio and TikTok Studio file inputs in browser memory, then syncs the published YouTube Video ID right back to BMDS.
Zero-Quota Multi-Language .srt Subtitle Uploader: Public YouTube Data API v3 caption uploads quickly exhaust daily free quotas. I built youtube_bridge.js to hook directly into YouTube Studio's internal Wiz (Hlm) and Polymer (J9) dependency-injected services, auto-translating and publishing localized titles, descriptions, and .srt subtitle tracks in one click.
Automated @YouTuber Channel Mention Resolver: Resolves @handle mentions into canonical /channel/UC... IDs and injects native YouTube Studio mention chips automatically.

🛠️ Suno React Bridge & DistroKid Album Mastering

Suno WAV, Multitrack Stems & MIDI Auto-Exporter: Human-paced state machine on suno.com that exports master WAVs, full multitrack Stems.zip + MIDI files, auto-matches 01_-99_ track numbers from local .md lyric files, and inspects React Fiber state to restore hidden model versions.
DistroKid-Ready Album Sequencer & Mastering Suite: Sequences full albums in STEMS Studio, applies audio mastering and metadata tagging, extracts plain-text ## DistroKid lyric blocks, and exports a single distribution-ready Album ZIP for DistroKid, Spotify, and Apple Music.
Live DOM & Controller Diagnostics: Built a 1-click snapshot extractor that dumps Wiz controller maps and DI service keys whenever YouTube updates its frontend, enabling same-hour fixes via Antigravity CLI.

ENTERPRISE WORKFLOW INNOVATION SharePoint REST API CRUD Zero-SPPKG Bookmarklet Bootstrapper Human-in-the-Middle Agentic Patcher

6. SharePatch - Zero-SPPKG SharePoint Live Patching & Human-in-the-Middle CLI Pipeline

When corporate IT restrictions blocked SPFx .sppkg package deployments and restricted AI tooling to a chat-only Copilot window without CLI access, I engineered a self-hosted JavaScript IDE and batch-patching CRUD pipeline running directly inside SharePoint.

▾ Expanded

💡 In Plain English: At work, IT locked down SharePoint package deployments and only gave us a basic Copilot chat box with no command-line access. Instead of copying and pasting code snippets by hand all day, I built an in-browser patching tool (SharePatch) launched via a browser bookmarklet that lets me apply verified batch updates directly to live SharePoint files in one click.

🎯 Routing Around Enterprise Gridlock

Eliminating .sppkg Tenant Catalog Bottlenecks: Built a bookmarklet bootstrapper that dynamically loads and executes full JavaScript applications directly from the SharePoint SiteAssets document library inside any authenticated SharePoint site context.
Full Same-Origin SharePoint REST CRUD: By executing inside an active SharePoint origin, the application inherits native session authentication and X-RequestDigest tokens to perform full Create, Read, Update, and Delete (CRUD) operations across both SiteAssets source files and SharePoint List databases (/_api/web/...).

🛠️ Turning Chat-Only Copilot into a Batch CLI Pipeline

Human-in-the-Middle Structured Patching (SharePatch): Designed a strict batch-patch protocol so even a restricted, chat-only assistant (Copilot) outputs deterministic patch snapshots rather than vague prose.
Interactive Side-by-Side Validation & Live Apply: Pasting a batch snapshot into SharePatch validates target file lines against the live SharePoint file in one pane and applies multi-block updates directly to SiteAssets in one click.

Engineering Philosophy

Why Spec-Driven Antigravity Engineering Wins

There is a massive gap between pasting snippets out of a restricted chat box and operating an autonomous, verification-driven CLI agent environment.

Dimension	Chat-Only Assistants (e.g. Locked-Down Copilot Chat)	My Production Workflow (Google Antigravity CLI + Spec-Driven Architecture)
Context & Codebase Awareness	Fragmented single-file snippets; forgets cross-service invariants and hallucinates off-the-wall tangents.	Persistent `.agents/rules` & Skills: Full-repo grep/AST exploration, enforced architectural invariants, and zero unrequested regressions.
Execution & Verification Loop	Manual copy-paste-test loop where the human acts as a clipboard mule between browser and terminal.	Direct CLI Execution & Automated Verification: Multi-file atomic edits, syntax/unit test verification, and live local-to-VPS synchronization in one loop.
Complex Debugging	Guesses blindly when upstream APIs or DOM structures change.	Empirical Telemetry Inspection: Captures real runtime snapshots (e.g. YouTube Wiz DI state or SQLite locks) and fixes the exact root cause.
Delivery Velocity	Days of back-and-forth bikeshedding for medium features.	Principal-Level 10x Throughput: Full-stack endpoints, UI portals, and production deployments shipped and verified in minutes.
