Designed the blockchain transaction flow for investor participation, wallet integrations, and token claiming systems.
Developed the admin panel for managing users, token sales, analytics, and platform operations.
Built the user dashboard where investors could track purchases, manage allocations, and monitor token-related activity.
Developed backend systems using Node.js for secure API management, user authentication, transaction tracking, and dashboard operations.
Built frontend systems using React.js to create fast, scalable, and user-friendly investor experiences.
Integrated wallet connection systems and payment workflows for seamless token purchases.

Built and optimized WordPress websites for marketing and organic growth with strong technical SEO foundations.
Improved SEO performance through optimized architecture, Core Web Vitals improvements, structured data, metadata systems, and search indexing optimization.

This experience allowed me to combine blockchain engineering with product development and SEO strategy, building systems that were both technically strong and growth-focused.
Working across smart contracts, backend systems, frontend dashboards, and SEO-focused web platforms strengthened my expertise in full-cycle Web3 product development.
