Justin Rudio Systems Architect & Engineer
Google Cloud & Systems Architecture

Architecting resilient cloud systems and high-craft native software.

I am a systems architect and software engineer with extensive experience across Google Cloud Platform, the Google Cloud Agent Platform, declarative infrastructure, and edge-computed consumer applications.

Background

Engineering Ethos & Leadership

With over 4 years of specialized experience in Google Cloud architecture alongside more than 12 years of full-stack and systems programming, I focus on building high-reliability platforms that eliminate operational friction and unnecessary complexity.

My work spans containerized serverless microservices on Google Cloud Run, declarative Infrastructure as Code with Terraform and Pulumi, and the Google Cloud Agent Platform for deterministic enterprise agentic workflows.

In parallel, I am the founder of PotatoDog LLC, an independent software studio building privacy-first consumer applications that run machine learning models directly on client hardware.

Competencies

Core Systems & Architecture Domains

Deep technical experience spanning high-throughput cloud infrastructure, deterministic agentic engineering, and native client software.

Google Cloud Platform & Serverless

High-throughput architectures on GCP Cloud Run (Gen2), Cloud Firestore, Cloud Pub/Sub, Artifact Registry, IAM security policies, VPC Service Controls, and Google Kubernetes Engine (GKE). Focused on sub-50ms p99 latency and efficient concurrency calibration.

Cloud Run Cloud Pub/Sub Firestore GKE IAM / VPC

Google Cloud Agent Platform & AI

Designing agentic workflows with the Agent Development Kit (ADK), hosting on Agent Engine, integrating Model Garden foundation models, and implementing deterministic tool-calling, RAG architectures, and evaluation pipelines.

Agent Platform ADK & Agent Engine Model Garden RAG

Infrastructure as Code & Zero-Drift

Declarative cloud infrastructure provisioning via Terraform and Pulumi (Go SDK). Enforcing immutable container SHA256 digest pinning in Artifact Registry to guarantee zero-drift deployments and clean supply chain security.

Edge Computing & Native Mobile

Compiling quantized Small Language Models via native `llama.cpp` runtimes with GPU acceleration (Metal/Vulkan). Native iOS engineering with SwiftUI and Swift Concurrency, paired with NIST P-256 hardware cryptography over Bluetooth Low Energy.

Systems Architecture & Case Studies

Engineering teardowns dissecting performance optimization, declarative infrastructure, and on-device model runtimes.

CLOUD RUN & SERVERLESS OPTIMIZATION CASE_01

Eliminating Cloud Run Cold-Starts & Tuning p99 Concurrency

Detailed breakdown of CPU throttling behaviors in containerized serverless runtimes. Explores how converting bloated multi-layer images (450MB) to scratch/distroless multi-stage builds (14MB), combined with calibrated instance concurrency and always-on CPU allocation, reduces p99 scale-out latency from 2,800ms to sub-50ms.

CPU Idle Tuning Distroless Multi-Stage Concurrency Calibration
DECLARATIVE INFRASTRUCTURE CASE_02

Zero-Drift Pipelines with Terraform, Pulumi & SHA256 Pinning

Preventing split-brain production releases caused by mutable container tags. Demonstrates how type-safe IaC models in Go and Terraform resolve immutable SHA256 container image digests from Artifact Registry to establish verifiable cryptographic provenance in CI/CD workflows.

Artifact Registry Immutable Hashes Supply Chain Security
AGENT PLATFORM & ADK CASE_03

Deterministic Agentic Systems via Agent Development Kit

Architecting production agents on the Google Cloud Agent Platform. Covers tool-calling schemas, state synchronization with Agent Engine, and evaluating response quality and grounding using automated evaluation suites.

Agent Development Kit Agent Engine Model Garden
EDGE AI & EMBEDDED SILICON CASE_04

Compiling Native SLMs (`llama.cpp`) for Mobile & Automotive Edge

Embedding quantized Small Language Models directly onto iOS and Android runtimes. Pairs local inference with Apple Secure Enclave / Android Keystore for NIST P-256 cryptographic command signing over Bluetooth Low Energy without cloud dependencies.
