- Otaku Web3 Crowdfunding: Project Manager leading Otaku Web3 Crowdfunding end to end—driving discovery, scoping, and roadmapping for a platform where teams pitch IP-licensed anime projects (e.g., a One Piece event), route proposals to rights holders for review/approval with profit-share terms, and—once approved—automatically deploy a fundraising token. I defined token economics and a price-priority auction (investors bid; higher prices win allocations up to a fixed supply, e.g., 1,000 tokens with $0.10 floor), specified smart-contract flows for minting, allocation, and vesting/claim schedules that stream tokens over periods and distribute pro-rata profits at each claim. I coordinated product/design/engineering, ran sprints and delivery, and oversaw architecture for wallet connectivity, KYC/AML gating, allowlists, and on-chain/off-chain services (indexers/subgraphs, notifications, dashboards).

I defined domain models and RBAC, content moderation/workflows for editors, and notification rails (match start, upset alerts, favorite team updates) using Telegram’s APIs. I set non-functionals—observability (logs/metrics/traces), rate limiting and abuse protection, privacy and data retention, HA/DR, and cost controls—while establishing CI/CD, infra-as-code, automated tests, and performance budgets.
