Ai & Web3 Full Stack Developer

Full-stack developer focused on AI applications, SaaS platforms, and Web3 products.

My core stack includes Next.js, React, TypeScript, Supabase, PostgreSQL, Tailwind CSS, and modern AI tooling such as OpenAI, Claude, and AI agent workflows.

Over the past few years, I have built production-ready web applications including AI sales systems, SaaS comparison platforms, workflow automation tools, Web3 dashboards, and subscription-based products. I enjoy turning ideas into working products quickly while maintaining clean architecture and long-term maintainability.

I am particularly interested in remote opportunities involving:

• AI-powered products and agent systems
• SaaS platforms and startup MVPs
• Web3 applications and blockchain tooling
• Product-focused frontend and full-stack development

I work well in fast-moving startup environments, communicate clearly, and enjoy collaborating directly with founders to transform concepts into scalable products.

Currently available for remote contract, freelance, and long-term opportunities worldwide.
