Executive Technology Leader/CTO specializing in data platforms, AI agents, and e-commerce/payments

Los Angeles, CA23y exp

“Engineering leader with hands-on coding time who has driven major commerce and data-platform transformations: defined goop’s omnichannel strategy, unified payments to Square, and rebuilt real-time NetSuite inventory flows plus forecasting tools. Currently reorganized engineering into Product/Data/Support teams to hit aggressive seasonal roadmaps, and led a data-lake/medallion ELT refactor feeding embedded analytics (Tinybird) with improved reliability and cost efficiency; also accelerates onboarding via AI coding tools in a serverless, event-driven architecture.”

“Engineering/technology leader with experience tying roadmaps to OKRs/KPIs, scaling cross-functional engineering teams, and driving go-to-market execution for Managed IT Services revenue growth. In an early-stage company setting, personally stood up core systems (CRM, lead gen, website) and multi-cloud infrastructure (GCP/AWS) while building investor materials (pitch deck, VDR, financials), resulting in an investor LOI within 8 months. Also led an on-prem deployment architecture redesign for a network monitoring (NPM) product to improve compatibility, scalability, and security.”

Executive Game Systems & Animation Engineering Leader specializing in console and Unreal/Unity

California, USA26y exp

“Unity/C# engineer with AAA and social MMO experience who owned and shipped a marquee VR gameplay system for Meta Quest, using advanced 3D math and closed-form optimization to maintain a solid 60 FPS on constrained hardware. Also builds LLM systems from first principles and integrates native inference into C# pipelines, and has deep multiplayer architecture experience (Photon/Netcode/frame sync) including fault-tolerant WebSocket messaging for mobile connectivity dropouts. Prefers contract work; time zone flexible (EST).”

“Hands-on architect/executive who built a virtual sales platform from scratch with real-time video delivery and autoscaling global video nodes, while also operating at the stakeholder/roadmap level.

“Engineering/technology leader (CTO-style) with experience scaling orgs and running distributed teams across four continents for over a decade. Led a high-stakes modernization of a securities trading platform at Wedbush—migrating from monolith to microservices on AWS with zero-downtime constraints—driving 45% execution performance improvement and enabling 25% market share growth. Emphasizes business-aligned roadmaps, build-vs-buy rigor, and scalable engineering practices/culture.”

“Engineering/product leader who builds business-aligned technology roadmaps and scales pod-based orgs with strong delivery discipline (OKRs, CI/CD, QA automation). Led a SaaS supply-chain application adopted by Fortune 100 customers, citing ~$4M MRR and ~87% gross profit, and has hands-on experience standardizing LLM + cloud/MLOps architectures with security/compliance guardrails. Also created the PISEK methodology and used it to run distributed innovation sprints (e.g., an AI ETA predictor moved from pilot to production).”

“Gameplay engineer with hands-on ownership of a computer-vision body-tracking system that powered Dance Break, a full-body dance game shipped across Windows, Mac, iOS, and Android and used at large live events like EDC Las Vegas and Alibaba CoCreate. Particularly strong in performance-sensitive Unity systems, cross-platform optimization, and multiplayer architecture decisions, with experience spanning mobile, VR, and deterministic networking.”
