Has shipped/implemented stealth gameplay systems including power-ups (notably an invisibility mechanic) and iterated features through internal cross-discipline playtests, documentation, and Figma-driven inventory system alignment.”

“Game/content designer with experience at EA and on a mobile title (Ultimate Fishing), owning PvP mode UX/gameplay improvements and building UE5 Blueprint systems (state machine + modular weapon/ability architecture) to support multi-developer teams. Also designed College Football 2025/2026 challenge content grounded in real football culture and research, improved broken data-driven toolsets via spreadsheet formula work, and partnered with economy to rebalance rewards by rapidly shipping additional challenges.”

“Lead game designer/producer who shipped a Fortnite TMNT-themed rogue-like dungeon crawler, owning progression, economy, and tuning. Improved retention measurably by replacing a linear points system with an exponential economy formula, increasing playtime by ~50%, and iterated quickly via playtests (mini-boss pacing, weapon drop-rate balance). Also built UE Blueprints for FPS animation montages and state transitions to address clunky movement feedback.”

“Data Software Tools Analyst at Q.ai through rapid growth and a $2B Apple acquisition who led an internal CMS for participant/PII workflows using Next.js (App Router) + FastAPI/Postgres with strong security controls (JWT + Postgres RLS). Also drove a major frontend architecture shift toward React Server Components, reporting ~4x faster page loads, and has experience building durable realtime collaboration systems with Supabase/SvelteKit and server-centric state management.”

“Lead hardware/integration engineer on a high-speed autonomous drone for adversarial drone tracking and surveillance, owning the full stack from custom electronics and flight-controller tuning to ROS2 SLAM and GPU-accelerated computer vision. Built a custom USB-based ROS2 LiDAR driver and migrated SLAM from SLAM Toolbox to Google Cartographer, while boosting YOLOv5 tracking from ~2 FPS to ~45 FPS on an NVIDIA Jetson through CUDA/dependency optimization.”
