CicaTavernAn agent-style tavern for SillyTavern character cards — import cards, world books and presets, and play them on your own model API. Prompts are laid out for caching (a median 97% cache hit per turn in long chats); "good role-play" is written down as preset rules and card-writing checks, and bad replies are traced to their causes with a small eval.
Hold the LineA 1v1 online card battler — Hearthstone-style mana tempo layered over a 5×4 grid battlefield, where minions deploy, advance and block, and you win by pushing them past the enemy line.
Ninja Gaiden 4Engine support and performance work for PlatinumGames' flagship action title — software occlusion culling, multi-platform quality presets and GPU stability.
nestA multi-platform AI bot app I wrote — one background process runs three QQ group-chat bots, each with its own persona. Its project Q&A was designed from eval results — a local reranker decides whether the docs cover a question, an LLM picks which sections to read — taking correct answers on real questions from 79% to 98%.
EatWhat TonightA pixel-art survivors-like where a slime evolves by eating — fight, snack, pick evolutions, and let AI cook up foods that exist only in your run. It is also a methodology experiment: when almost all the code is written by AI, how do you make its output trustworthy?
Liberty Engine Ocean SystemThe open-world ocean module of PlatinumGames' in-house engine — FFT seas, shoreline waves, whitecaps and water interaction, shipped in Ninja Gaiden 4 and more.
EdenaAn in-development UE5 first-person action game — summoning, combat, interaction and inventory, with architecture as the selling point.
PodEchoAn AI podcast digest service — subscribe to your favorite podcasts and creators, and get every new episode as a digest email you can read in minutes.
Former OceanA VR environmental education game starring a dolphin — use sonar to sense danger and clues, and cross polluted waters back home. National First Prize winner.
DeskPetA desktop companion app — a transparent, always-on-top cat lives at the edge of your screen and gently reminds you to drink water and stretch.
MissingA roguelike × ARPG action demo — enemy AI that adapts its strategy to player behavior and surroundings, plus a combat system built for feel.
