Head of Engineering & Principal Architect

Frontiers Market

January 2025 – April 2026• 1 yr 3 mo• full-time

Leading the technical vision for an AI-driven platform digitizing the cattle industry. Orchestrating the convergence of Edge AI hardware, native mobile interfaces, and complex financial settlement systems.

• Agentic Operating Model & Swarms: Architected and deployed full agentic swarms with multi-level orchestrators. Designed swarm leaders to act with minimalized context, automating complex decision-making pathways and significantly improving operational efficiency without human-in-the-loop bottlenecks.
• Proprietary Edge AI Architecture: Engineered a custom, local-first NVR solution using Raspberry Pi clusters and local RTSP streams. Bypassed off-the-shelf limitations to process video stream handling and storage locally, reducing cloud dependency while maintaining real-time livestock monitoring.
• Fintech & Escrow System (clear.frontiersmarket.com): Designed and built a secure auction payment rail using Stripe Connect with "separate charges and transfers" logic to hold funds in escrow until delivery verification — designed to replace legacy check-based workflows with a digital ledger. Built but not yet live in production.
• Offline-First Native Mobile (app.frontiersmarket.com): Led the development of a native Swift application (Frontiers Market AI) capable of estimating cattle weight via on-device computer vision, ensuring functionality in low-connectivity rural environments via store-and-forward data sync.
• Marketplace Engineering: Built the core registry and management application, enabling disparate ranchers to manage records, track livestock lineage, and transact securely using PostgreSQL for transactional integrity, utilizing Redis caching to optimize high-frequency inventory lookups.

Co-founder & Chief Technology Officer

Firefly Events Inc

September 2023 – Present• 3 yrs 2 mo• entrepreneur

Bootstrapped Firefly Events and built a suite of products — Shindig (aggregating 8,000+ daily events), Reserved, Tabletop Archive, and Flayr — live or launching. Adoption is still early: not yet enough signups to call any a fully proven product.

• Agentic Swarm Orchestration: Architected autonomous agent swarms to manage complex cross-repository dependencies and third-party integrations (Stripe, Shippo, Maps). Automated critical workflows — from deep linking and website updates to sales tracking — optimizing API context usage and significantly reducing operational overhead.
• "Shindig" (Consumer Discovery - https: //shindig.ff.events): Engineered a high-performance native mobile aggregator (iOS/Android) using Kotlin Multiplatform (KMP). Aggregates data from Ticketmaster, Eventbrite, and Facebook to serve as the "Travelocity of Events," utilizing geo-spatial queries for real-time discovery.
• "Reserved" (Venue SaaS - https: //demo.reserved.ff.events): Architected a Next.js venue management platform backed by MongoDB, utilizing flexible schema design to power a complex dynamic rules engine. Solved for intricate NYC "block laws" by allowing venues to configure conditional booking logic (e.g., "Food purchase required for alcohol service").
• "Tabletop Archive" (P2P Marketplace - https: //tta.games): Built a rental platform using Convex DB and Next.js. Implemented inventory state machines, Stripe financial logic, and fraud prevention using Shippo to manage asset depreciation and restrict shipping actions.
• "Flayr" (https: //flayr.social): Built an AI-driven B2B content engine — automated content creation, scheduling, and cross-posting across multiple social accounts. In active internal use (dogfooding) and launching.

Senior Software Engineer (Supply Chain Tech)

Wayfair

May 2022 – January 2025• 2 yrs 8 mo• full-time

Led critical initiatives within the supply chain technology group, driving operational efficiency for a global e-commerce giant.

• Supply-chain initiatives: Led and shipped supply-chain data work within the team's assigned scope — several initiatives self-originated — designing event-driven fixes for data failures driving lost and disappearing product in returns and inventory reconciliation. The business credited the broader supply-chain effort with about $5M/year in reduced lost-inventory cost; this was one of several contributing initiatives, and impact wasn't tightly instrumented.
• Cross-Functional Leadership and Platform Standardization: Acted as a technical mentor for junior engineers and collaborated across Product and Data Science teams to standardize API documentation and microservice deployment protocols.
• Supply Chain Tooling: Built internal tools that rectified supply chain workflows, improved image pipelines, reduced fraud, and optimized day-to-day operations and mobile experience.
