Project details
Looking for a Zero-Knowledge Proof (ZK) expert to build privacy-focused Web3 solutions?
I specialize in designing and implementing scalable, secure, and production-ready applications using cutting-edge ZK technologies such as ZK-SNARKs, Groth16, Plonk, Circom, and Noir.
I can help you with:
✅ Custom ZK circuit design and implementation
✅ Proof generation and verification (Groth16, Plonk)
✅ Integration with SnarkJS, Halo2, zkSync
✅ Smart contract integration on Ethereum, Solana, Polygon, and other chains
✅ ZK-based encrypted chat systems with Poseidon Hash, ECDH, and access control
Whether you need a Tornado Cash-style mixer, anonymous voting platform, private messaging app, or any custom ZK-powered dApp, I can deliver a solution tailored to your needs.
With 2+ years of full-stack and blockchain development experience, I ensure your project is secure, optimized, and ready for production.
🚀 Let’s bring your Zero-Knowledge-powered application to life!
