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 optimize video stream processing and storage, significantly reducing cloud ingress costs while maintaining real-time livestock monitoring.
• Fintech & Escrow System (clear.frontiersmarket.com): Designed and shipped a secure auction payment rail using Stripe Connect. Implemented "separate charges and transfers" logic to hold funds in escrow until delivery verification, replacing legacy check-based workflows with a compliant digital ledger.
• 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.

Founder & Chief Technology Officer

Firefly Events Inc

September 2023 – Present• 2 yrs 8 mo• Entrepreneur / Side Project

Bootstrapped and launched a comprehensive event ecosystem comprising three distinct SaaS and consumer products processing 8,000+ daily events.

• 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.
