I’m a full-stack & Blockchain developer with a strong focus on Next.js and Node.js, and I specialize in building clean, scalable applications from frontend to backend.

Here’s how I match your requirements:
✅ Frontend: I work with Next.js/TypeScript , React, Material UI, TailwindCSS, and Sass to build fast, responsive interfaces. I also use Redux for state management and work in design systems using Storybook to maintain UI consistency.
✅ Backend: I use Node.js/TypeScript and create RESTful APIs. I'm also comfortable setting up secure API routes in Next.js.
✅ Blockchain: Solana, Solidity, Web3, hardhat, ethers.js, etc.
✅ Database: Experienced with both SQL and NoSQL systems, especially Supabase, PostgreSQL, MySQL, and MongoDB.
✅ Testing: I use Jest and related tools for frontend/backend testing to ensure functionality and stability.
✅ DevOps & Deployment: Familiar with deploying apps on Vercel (including setting up environment variables, preview deployments, and GitHub integrations). I also work with Jenkins, Docker, CI/CD pipelines, and GitHub Actions for PR checks and automated testing.
✅ Other tools: I am focusing on improving communication skills in design and API development by using tools such as postman and Insomnia and integrating with swagger.

I’m used to tight timelines and iterative development, and I always aim for clean code and practical delivery.

I am open to work for you.
