At BitTasker, I built a decentralized freelance marketplace combining user-owned cryptographic identity, verifiable reputation, and escrow-based payments. I led front-end development and contributed across authentication, messaging, contract management, and payment settlement.
I implemented passwordless WebAuthn authentication and Nostr integration, and developed a multi-chain wallet SDK supporting HD key derivation, atomic swaps, EVM transactions, and gasless claiming. I also built a reputation system tied to proof of completed on-chain settlements and automated web and mobile releases through GitLab CI.
At KJR TeleCom (YooDooGood), I built a rewards platform where users earn in-app currency and redeem it for physical prizes. I developed 13+ casual games, integrated Stripe subscriptions and gift card redemption, and built an administrative dashboard for platform operations.
