Professional Summary⚑

Python engineer and AI-First practitioner with 19+ years of experience architecting production-grade software across cloud-native platforms, enterprise API ecosystems, and AI-powered backend systems.

Deep expertise in Hexagonal Architecture, multi-tenant security patterns (3-Factor Identity), and resilience engineering (Circuit Breaker state machines achieving ~40% cascading failure reduction). Demonstrated track record of delivering high-quality, audit-ready features in Agile environments — from designing and deploying FastAPI applications on GKE to architecting framework-agnostic domain cores with zero technical debt.

Core Competencies⚑

  • Architectural Patterns: Hexagonal Architecture (Ports & Adapters), Dependency Injection, Domain-Driven Design (DDD), Framework-Agnostic Core Isolation, SOLID.
  • Python Engineering: FastAPI, Pytest (BDD/TDD), Playwright, Pandas, NumPy, Matplotlib, Pydantic, Strongly-typed Python (frozen dataclasses).
  • Resilience & Fault Tolerance: Circuit Breaker state machines (CLOSED → OPEN → HALF_OPEN), Exponential Backoff with Jitter, Cascading Failure Mitigation.
  • Security & Identity Governance: 3-Factor Multi-tenant Isolation (JWT + Header + Infrastructure), Zero-Trust Architecture, Okta SAML/OIDC Federation.
  • AI-First Development: GitHub Copilot (Certified), Google AI Professional (Feb 2026), GCP ADK, LLM-assisted engineering workflows, Prompt Injection Threat Modeling.
  • Cloud & Deployment: Google Cloud Platform (Professional Architect), GKE Autopilot, Cloud Run, AWS Migration, Terraform/Terragrunt, GitHub Actions.

Professional Experience⚑

Aumovio (Formerly Continental) | Taguig City, Philippines⚑

Lead Developer (Platform Architecture Scope) | Jul 2025 – Present⚑

  • AI-Powered Feature Delivery (Python/FastAPI): Designed and deployed a Secure FastAPI Broker on GKE as a multi-protocol reverse proxy for Okta-integrated applications, enabling centralized inspection of OIDC, SAML, and OAuth2 flows.
  • AI-First Engineering Practice: Championed AI-augmented engineering workflows using GitHub Copilot and Google AI tooling; led LLM-assisted engineering pilots that accelerated internal platform development velocity.
  • AEC AI Agent (GCP Vertex AI / ADK): Built a production AI agent orchestrating Jira, Gitea, and GCP Secret Manager via FastMCP; enforced multi-tenant security via Okta Private Key JWT and prefix-scoped Secret Manager access.
  • Cloud-Native Deployment & CI/CD: Provisioned and automated GCP/AWS environments using Terraform and GKE Autopilot; led ground-up GCP rebuild delivery for legacy AWS platform capabilities.
  • AI Agent Architecture & Quality Governance: Designed and validated an Okta-governed, identity-centric AI agent architecture for GCP ADK; evaluated threat mitigations including prompt injection and data exfiltration.

Senior Consultant – MES Integration & Product Owner | Jul 2014 – Jun 2025⚑

  • Python Automation Framework: Architected and delivered a Python-based BDD automated testing framework (Playwright/Pytest) enforcing data contract validation; delivered an 80% reduction in manual QA labor.
  • Agile Product Delivery at Scale: Led SAFe 6 Product Ownership for Core MES modules across APAC/EMEA/NAFTA; managed backlogs and PI Planning across global Agile Release Trains.
  • Parallel Platform Engineering: Managed functional parity of application modules across VM and Kubernetes-based environments during a high-stakes migration; enforced zero data-loss standards.
  • Data Analysis & Reporting (Python): Leveraged Python (Pandas, NumPy, Matplotlib) and Power BI to produce operational quality dashboards and compliance reports.

Manufacturing Application Integration Consultant | May 2010 – Jun 2014⚑

  • API & Interface Engineering (C#, SQL, TCP/IP): Developed critical system interfaces bridging shop-floor equipment with enterprise data layers, establishing end-to-end traceability.
  • Regional Platform Standardization: Led migration of APAC pilot production lines to standardized MES platform across a distributed multi-site environment.

Texas Instruments | Baguio City, Philippines⚑

Test Product Engineer | Nov 2005 – Apr 2010⚑

  • Improved manufacturing yield by 6% and operational efficiency by 5% by developing a real-time IDDQ monitoring and thermal runaway prevention tool (Perl, SQL/Oracle).
  • Accelerated production ramp-up for new semiconductor devices by optimizing test programs and conducting rigorous Gauge R&R studies.

Selected Projects⚑

Hardened Architecture & Multi-Tenant Security⚑

Stack: Django 5.x, Next.js 14, PostgreSQL, TypeScript, PlantUML

  • Framework-Agnostic Core Domain: Isolated 100% of business logic into a core/ package with zero framework imports; decoupled domain models via Dependency Injection.
  • 3-Factor Multi-Tenant Isolation: Implemented strongly-typed tenant identity validation with fail-closed enforcement; zero violations across full test suite.
  • Circuit Breaker State Machine: Designed a full state machine (CLOSED → OPEN → HALF_OPEN) reducing cascading failures by approximately 40%.
  • PlantUML Architectural Documentation: Produced high-fidelity diagrams for Hexagonal Architecture, 3-Factor security, and Circuit Breaker patterns.

AI-Powered Identity Broker (Personal Python Project)⚑

Stack: FastAPI, Okta, OpenTelemetry, Docker

  • Built a FastAPI multi-protocol identity broker intercepting Okta OIE OIDC (PKCE, JWKS verification) and SAML flows; exposes data to AI agents via FastMCP.
