Mid-level Design Engineer specializing in product design and front-end implementation

New York City, NY4y exp

“Product designer-builder who codes, with a rare end-to-end profile spanning product strategy, UX, design systems, frontend engineering, and AI integration. Built PetCloud/PetClub as a fully solo product in Next.js/TypeScript/Supabase and has also driven measurable UX gains in company settings, including 25% higher engagement, faster design-to-dev handoff, and fewer UI bugs.”

“Full-stack developer with seven years of experience who has built production systems across AWS serverless infrastructure, Django applications, and user-facing web products in domains like emergency response, fintech/investing, recruiting, and conference management. Particularly notable for combining technical architecture with product thinking—e.g., modernizing a crash-tracking platform for emergency responders and materially improving trust-driven conversion in a trading-card fractionalization product.”

“Unity gameplay engineer who has shipped mobile and Meta Quest VR titles, leveraging DOTS/ECS for large-scale war/rts-style scenes and mobile performance. Built multiplayer features using Photon PUN 2 with PlayFab matchmaking/backend and implemented live network debugging/recovery strategies. Also prototyped an AI/LLM-assisted pipeline for generating and validating gameplay/level content via structured JSON with fallbacks and caching to control reliability and cost.”

“Backend/AI engineer with deep healthcare experience building production Python microservices that turn raw clinical audio into structured notes and insights. They owned systems end-to-end across architecture, launch, monitoring, and incident response, with measurable impact including 40% lower operating costs, 22% better latency, and 99.9% uptime in a regulated environment.”

“Backend engineer (Encore) who led the evaluation and redesign of a high-volume, low-latency real-time retrieval/ranking and inference platform on AWS, shifting from tightly coupled services to a modular architecture for better fault isolation and independent scaling. Strong focus on production reliability, observability, and security (JWT/RBAC, multi-tenant scoping, Postgres/Supabase RLS), with disciplined migration playbooks (feature flags, shadow traffic, dual writes/reconciliation).”

“Backend engineer who has led redesigns and migrations for a real-time logistics platform, improving scalability and resilience while managing eventual consistency tradeoffs. Demonstrates strong distributed-systems rigor (idempotency, transactions, async queues, monitoring) and builds secure, versioned FastAPI APIs with JWT/OAuth2, RBAC, and database row-level security.”

“Unity game developer who single-handedly coded and designed a physics-based ski simulator for MAE Content, including a custom spring-like skiing model built on Rigidbody physics. The simulator was deployed in a museum setting and became the most frequently visited exhibit, with strong player satisfaction reported.”

“Unity gameplay programmer who built a high-impact "furniture influence" system for a RimWorld-like base builder, adding spatial synergy that changed how players approached building.
