At Rowship, I built LiquiCrowd end to end, a platform for crowd-funded on-chain credit vaults on Flare. I also integrated KYC/KYB onboarding with Sumsub and created an admin diligence workflow with document review, decisions, and an audit trail.

At Rowship, I automated the vault lifecycle with scheduled jobs and shipped three React Native apps to the App Store and Google Play. I also built HackAlerts, a real-time DeFi exploit alerting service with LLM-based triage and a human review step.

Previously, at CloudnonicCorp., I built backend services in Python and Node.js and developed React features for AI productivity tools. Across earlier roles, I contributed to projects involving prediction markets, subscriber migration, REST APIs, and client websites.
