Full-stack engineer with a product-first mindset and a background in finance.
I build end-to-end web products, from UI and APIs to auth, data models, and deployment. I’m comfortable owning features from idea to production in small, fast-moving teams.

Business registration & management on blockchain.

• Led a 4-person team: scoped MVP, broke work into issues, assigned ownership, and drove daily shipping
• Owned core product flow: onboarding → entity creation → management dashboard
• Implemented frontend + backend integrations for blockchain interactions
• Shipped a demo-ready end-to-end experience under hackathon constraints; project is still actively developed
