Building AI applications and reliable infrastructure

I work with teams to understand their needs, evaluate technical options, and build software they can use and maintain. My experience spans enterprise presales, global infrastructure, and production AI applications.

Current product engineering and contributions from prior roles.

RaceControl

Grid Logic / Founder & Principal Engineer / 2025–present

RaceControl motorsports platform

Motorsports operations bring together people, telemetry, video, setup information, and decisions made under time pressure. I designed and built a mobile and SaaS platform that connects those workflows, with an offline-first application and AI grounded in team data.

Product and platform ownership

  • Flutter application delivery across iOS, Android, and web, with an encrypted offline cache.
  • GCP and Firebase services, tenant isolation, authentication, subscriptions, and deployment operations.
  • Asynchronous video processing and publishing pipelines using Cloud Run, Cloud Tasks, and FFmpeg.

AI workflows and reliability

  • A stateful operations agent that gathers pipeline health, recommends corrective actions, and dispatches only actions allowed by application controls.
  • A separate multimodal retrieval pipeline that grounds coaching reports in telemetry, video, documents, and prior analyses.
  • Retries, model fallback, structured-output validation, and deterministic degradation when AI is unavailable.

Engineering decisions behind the system

The model recommends an action; application code validates and executes it. This keeps authority in a controlled execution layer. Team-scoped retrieval and data-attribution checks protect context boundaries, while duplicate-work prevention and audit records make asynchronous operations easier to investigate.

The retrieval pipeline combines Vertex AI embeddings with Firestore vector search and a chronological fallback. A shared model gateway handles timeouts, retries, JSON parsing and repair, and model routing. The operations agent can preserve its output contract with deterministic rules when Gemini is unavailable.

Workday

Senior Infrastructure Systems Engineer
Network Observability & Edge

Network visibility across six global data centers

I architected and operated a packet-capture and network-observability ecosystem indexing 9 TB per hour across six global data centers. I owned the lifecycle of more than 240 network tap and aggregation devices, from evaluation and architecture through deployment and migration.

As a final escalation point for critical incidents, I worked across application, network, platform, and security teams to turn ambiguous symptoms into actionable findings. That work helped reduce critical-incident resolution time by approximately 80% while sustaining 99.9%+ availability.

2017–2019

Loom Systems

Senior Solutions Engineer
AIOps & Log Analytics
Later acquired by ServiceNow

Enterprise AIOps evaluations and customer enablement

I owned 15+ Fortune 1000 technical engagements spanning discovery, qualification, architecture, demonstrations, proofs of concept, implementation, and enablement. I mapped workflows, established evaluation criteria, and built parsers, API integrations, and telemetry pipelines.

I authored proposals and statements of work, trained more than 200 customer stakeholders, and contributed to a 40% increase in enterprise deployments. The through line was helping customers understand what the technology could do for their operations and how to put it to work.

2008–2015

The Common Application

Director, IT Services
Secretary of the Association

Technology and institutional relationships at national scale

I combined presales work, technology leadership, and high-touch relationships with admissions leaders during growth from 346 to 615 member institutions. The work required balancing individual institutional needs with a shared national platform.

I led infrastructure and service-delivery strategy, managed operational and project budgets exceeding $10 million, and represented the organization at national higher-education conferences. This experience continues to shape how I listen, explain tradeoffs, and steward consequential client relationships.

Working approach

Customer discovery through operational support

Understand customer needs

Start with the people, the workflow, and the outcome. Establish what success means before deciding what to build or buy.

Evaluate technical options

Use demonstrations, real data, and explicit evaluation criteria to help technical and business stakeholders make informed decisions.

Plan for production and handoff

Design for failure, access boundaries, and handoff. Documentation, enablement, and production troubleshooting are part of delivery.

Motorsports

Trackside work with racing teams

My motorsports work connects the software I build with the people who use it.

Trans Am TA2

RACEMarketingUSA

Owner/driver Bob Accardo

I serve as Spotter and Engineer with RACEMarketingUSA in Trans Am TA2 competition. Working directly with Bob and the team keeps me close to the communication and operational demands of race weekends.

Red Panther Motorsport

Owner/driver Reto Baumann

I also work with Red Panther Motorsport and owner/driver Reto Baumann in the US Touring Car Championship. That team connection brings another perspective to the day-to-day work of motorsports operations.

Background

A career in engineering and customer delivery

My career connects customer work with hands-on systems ownership. I’ve led technology and service delivery, guided enterprise evaluations, investigated production incidents, and built a product from its data model through mobile release.

My work with RACEMarketingUSA and Red Panther Motorsport informs the problems I choose to solve with RaceControl. It gives me a direct connection to the teams, conversations, and workflows behind the product.

I’m interested in senior individual-contributor work where technical depth, client trust, and collaboration matter. I hold an MS in Strategic Technology Management from Marist College and a BA in Computer Science from Vassar College.
