Technical Program Manager

Google — Core Data, Machine Learning & Infrastructure

New York, NY · November 2025 – Present

  • Co-lead multi-year compute, storage, and accelerator efficiency strategy across large-scale cloud and AI/ML infrastructure, driving 4–5% fleet-wide resource-efficiency targets with 80%+ high-confidence attribution coverage.
  • Architect automated capacity-governance workflows and analytical models that reconcile financial spending plans with physical cluster allocations.
  • Design and deploy production multi-agent AI orchestration systems, background event-stream daemons, and automated quality gates.
  • Drive technical program management across AI/ML, personalization, serving, and infrastructure-efficiency workstreams, with standardized RAID tracking and automated executive briefings.
  • Guide delivery of modular project-chartering, automated issue-tree health-monitoring, and continuous documentation-synchronization tools.
  • Mentor TPM interns and cross-functional contributors from system design through production launch.

Technical Program Manager (Contract)

Google

New York, NY · April 2025 – August 2025

  • Directed a search indexing modernization program for Google Drive — an 8,000+ engineering-hour initiative migrating legacy systems to a unified, sharded ST-Spanner backend.
  • Resolved a critical performance bottleneck by identifying resource contention, coordinating additional compute capacity, and eliminating service throttling.
  • Launched a unified request management system for a core authorization service, streamlining feature intake from Google Drive, YouTube, and other major teams.
  • Authored the official project management framework for the 100+ employee Storage Ecosystem, standardizing planning, estimation, and OKR alignment.

Projects

Muse Voicemail

Open Source — Android / Java

November 2026 · github.com/jonathancruzate/muse-visual-voicemail

  • A sideloaded Android reader for visual voicemail in the shared Android voicemail provider (VoicemailContract): list, playback, and transcription display, with a diagnostics screen that separates permission-blocked, empty, and source-scoped states instead of collapsing them.
  • REA (jadx) evidence against Samsung's Visual Voicemail showed its inbox is signature-walled in its own provider, so the app is built against the platform provider — with an optional default-dialer mode (dial pad, InCallService, VisualVoicemailService with the carrier-correct OMTP / Verizon VVM3 SMS filter) that is the only supported way to unlock voicemail read access on modern Android.
  • Framework-only, no AndroidX, built on a direct aapt2/d8 pipeline; includes the full REA dossier and Android VVM API research in the repo docs.

Muse–Gemini Spark A2A Bridge

Open Source — Google Sheets / Apps Script

November 2026 · github.com/jonathancruzate/muse-gemini-a2a-bridge

  • Event-driven agent-to-agent communication between two personal AI agents — Muse and Gemini Spark — with no human relaying messages and no hourly polling.
  • A shared Google Sheet is the mailbox (Requests / Results / Notes); a bound Apps Script On change trigger sends an "A2A-Event" alert email the moment a request lands, and an email-triggered Gemini Spark schedule processes the queue immediately.
  • Both directions ride the Sheet because custom-MCP write calls stall unattended Gemini runs on Allow/Deny prompts; requests stay structured JSON, matched and deduplicated by a per-request token.

Google Location Sharing Connector

Open Source — Python / Reverse Engineering

October 2026 · github.com/jonathancruzate/google-location-sharing-connector

  • Command-line reader for Google Maps Location Sharing — who is sharing with you, where, how fresh, and their phone battery — through the same internal RPC the Maps web app calls; no official API exists for this data.
  • Contract reverse engineered from the open-source locationsharinglib client with REA plus live probes; cookie-session auth with the session minted in a dedicated local Chromium, including a stdin-only password pipe that shreds its Password Manager export before parsing.
  • Corrected the source client's session-validation rule with live evidence — a live session still redirects through Google's SetOSID flow — so the connector validates against the RPC payload shape instead.

One UI 9 Meta Muse Widget

Open Source — Android / Java

October 2026 · github.com/jonathancruzate/oneui9-meta-muse-widget

  • Home-screen widgets and an ask page for Muse from Meta on Samsung One UI 9: the search bar reproduces the Finder bar from values decomposed out of One UI Home, and its pill composites a blurred wallpaper sample for a true frosted-glass read.
  • Reverse-engineered Muse's deep-link handling with jadx — payload deep links are gated by a Meta code-signing TrustedCaller check, so the app routes through the ungated ASSIST surface to land typed text in Muse's composer.
  • Includes an ask page with recent and predictive suggestions, a 71-destination link library, and a One UI-styled customize screen; built without Gradle on a direct aapt2/d8 pipeline.

Google Health Connector

Open Source — Google Health API

October 2026 · github.com/jonathancruzate/google-health-connector

  • Write path for Google Health and Health Connect built on the Google Health API v4 and the open-source ghealth CLI: reads and writes sleep, weight, and body fat.
  • Built as the migration path after the legacy Fitbit Web API shutdown (support ended September 30, 2026; endpoints off November 2, 2026) — verified by static analysis of the Google Health Android app that entries created through the API export to Health Connect as manually entered.
  • Documents the production-publishing fix for the 7-day Testing-mode OAuth refresh-token expiry, plus provenance rules for estimated health data.

Muse Connectors

Open Source — Python

October 2026 · github.com/jonathancruzate/muse-connectors

  • Custom connectors for Muse (Meta's personal AI agent) — the unofficial-API shelf.
  • Resy, Winix, SmartThings Find, and Google Location Sharing connectors, built and run in production.

Cronometer CLI

Open Source — Python

October 2026 · github.com/jonathancruzate/cronometer-cli

  • Command-line interface for Cronometer: diary logging, food search, nutrient targets, and biometrics from the terminal.
  • Reverse-engineered the Android app's private mobile API (Dart AOT binary reconstruction) to recover its token-based auth flow after no public API existed.
  • Date/time-pinned, read-back-verified writes with dry-run mode and a full offline test suite.

Muse File Search

Open Source — Python

October 2026 · github.com/jonathancruzate/muse-file-search

  • One search across local files, Google Drive, OneDrive, Dropbox, Google Keep, Google Photos, and email headers.
  • Prebuilt local indexes (~240k records) answer queries in about a second with zero model calls and no network — a deterministic script, not an LLM.
  • Watermark-incremental index refresh with a live CLI fallback on index misses.

Muse Smart Home

Open Source — Python

October 2026 · github.com/jonathancruzate/muse-smart-home

  • Smart-home automation patterns for Muse users, generalized from a real working home: one automation engine driving home, away, and night modes.
  • Three-source presence voting, spoken-alert routing over Google Home, SmartThings device control, and a universal MacroDroid macro for phone control.
  • Published as a fully scrubbed edition — every example device, name, and value is a fictional placeholder.
