🚀 Elite Networking & Strategic Horizons: Fully engaged in driving generative AI architecture at Google, but keeping a selective open channel for next-level frontier AI initiatives. If your Big Tech AI lab is actively looking for high-leverage AI engineers to bridge the gap between experimental R&D and market-disrupting agentic AI infrastructure, let’s talk.

My Resume
Professional Experience
20 years of professional software engineering experience, including 10 years pioneering state-of-the-art AI, physical simulation pipelines, machine learning, and advanced conversational systems at Google.
AI Software Engineer & Tech Lead (Global Office of the CTO)
- Engineered an automated Real2Sim procedural 3D physics generator to unblock Reinforcement Learning (RL) policy training for autonomous robotics; synthesized 3D meshes, collision primitives, and friction matrices in Blender 5.2+ from 2D vision extraction with Gemini critic loops, exporting scene graphs into MuJoCo MJCF for GPU-accelerated simulation in MJWarp with 95% spatial ingestion accuracy and a 100% collision-free physics pass rate.
- Architected a deterministic GraphRAG engine executing compiled Graph Query Language (GQL) on Google Cloud Spanner Property Graphs with a 3-tier database isolation model (Standard, Extension, Proprietary) and SQL-to-GraphSQL translation for global logistics supply chain platforms, achieving zero-hallucination multi-hop reasoning and transitioning architectures to Core Engineering to upgrade the Data Engineering Agent (DEA).
- Architected and delivered the nationwide Wendy's drive-thru GenAI speech automation engine as Technical Team Lead; invented and patented the Speech Utterance Finalizer (US20250078820A1) to eliminate human deliberation audio fragmentation, boosting order accuracy by 20%, cutting customer wait times by 15%, driving >1B PR impressions, and winning the Google Cloud Customer Empathy Award.
- Authored global developer whitepapers and technical guides reaching over 550,000 developers globally, including 300,000+ developers for Spec-Driven Development in 1H 2026 and 400,000+ downloads for the Kaggle Prompt Engineering Guide.
- Regained the Brazilian Supreme Court (STF) as a Tier-1 partner by architecting MultiDocAI, a time-aware legal reasoning pipeline that transformed open-ended generation into a constrained JSON-Schema ETL process, achieving 87% initial recall and precision up to 1.0.
- Pioneered next-generation multi-agent coordination frameworks and state machine orchestrators utilizing Gemini, Claude, and GPT-4, establishing architectural standards and secure cross-boundary communication protocols using LangGraph and GraphRAG.
- Managed a €100k+ annual budget and allocated 25% of leadership effort to product safety as Chapter Lead of the Pride@ Netherlands ERG, directly auditing harmful Dutch dictionary terms for the Google Assistant engineering team.
Senior Developer Advocate & Applied AI Engineer
- Orchestrated the open-source architecture of RCE360, a 622k-line omnichannel platform that resolved persistent state management across Twilio, Business Messages, and Assistant, personally contributing 5.5k unique lines of code and shifting the CCAI product roadmap toward CCaaS.
- Accelerated enterprise migration to Google Vertex AI by designing, open-sourcing, and presenting technical architectures as a keynote speaker at over 50 large-scale global conferences (including Google I/O and Cloud Next) to audiences of up to 5,000 developers.
Senior Customer Engineer (Enterprise Platforms)
- Engineered secure cloud migration roadmaps, distributed computing models, and integration architectures for Tier-1 multinational banking clients including ING and Rabobank.
Sales Engineer & Architecture Specialist (EMEA)
- Directed architecture consulting and customer-facing engineering alignments for strategic installations including BMW, CERN, and Thales.
Lead Technical Trainer (EMEA)
- Educated and certified engineering organizations at Fortune 500 platforms including NASDAQ, McAfee, Nielsen, and EMC.
Lead Front-end Developer & SWE Pod Manager
- Provided direct technical management and mentorship for a software engineering pod of 5 developers, scaling front-end integrations for market leaders including Heineken and Philips.
Senior Java Consultant
- Engineered transactional backend systems, scaling high-performance database routing for major airline and telecommunication clients including KLM/Air France and KPN.
